Ten questions and ten answers about stem cells, and I will learn about her magic with you.

Through ten groups of questions and answers, this paper gives you the function and application of popular science stem cells, and shows you the important position of stem cell therapy in modern medical care.

Mother, the pilot of the boat of life, not only gave birth to us, but also promoted the reproduction of mankind. She is a great inheritor of life and a transmitter of love.

Cells, the weavers of the web of life, constitute the cornerstone of the human body, which is a miracle exhibitor with various forms and complicated functions.

The human body is a magnificent movement interwoven with countless cells, the harmonious resonance of 240 kinds and 60 trillion cells, and the subtle fusion of 4 major organizations, 36 organs and 8 major systems.

She is a special cell, but also the guardian of the source of life. She can regenerate new cells, replace aging cells and repair damaged tissues and organs. She is the mother of the cell world.

This kind of cell is the root of our life-stem cells.

With the progress of science, stem cell research has become one of the most advanced and active research directions in the global medical field.

However, for the general public, what exactly are stem cells? What does it do? What kind of people are suitable for repair intervention through stem cells? What are the risks even in treatment? This article will help you understand these questions easily through ten groups of questions and answers.

Ten questions and answers about stem cells

01

What are stem cells?

Stem cells are cells with self-renewal function and multi-directional differentiation ability.

Under certain conditions, these cells can differentiate into more than 220 different functional cells in human body. Because of its remarkable homing effect, stem cells can repair and replace damaged cells and promote organ regeneration. They are the basic cells that constitute various tissues and organs of the human body, so they are known as "the source of life" and are often called "universal cells" in the medical field.

02

What are the classifications of stem cells?

Scientific research shows that stem cells exist not only in embryos, but also in adults, which can be extracted from cord blood, umbilical cord, placenta, bone marrow, fat and other tissues.

Stem cells are divided into totipotent stem cells, pluripotent stem cells and unipotent stem cells according to their extensive differentiation ability.

Stem cells can be divided into embryonic stem cells and adult stem cells according to their stages of embryonic development.

According to the tissue type of stem cell differentiation, it can be divided into hematopoietic stem cells and mesenchymal stem cells.

03

What is stem cell therapy?

"Stem cell therapy" refers to a medical intervention that extracts stem cells from patients or uses other stem cells, cultivates them under laboratory conditions, and then transfuses them into patients through specific transplantation techniques, so as to repair the cells and tissues that have lost their functions, thus promoting their regeneration and improving their symptoms. At present, hematopoietic stem cells and mesenchymal stem cells are widely used in clinic.

04

What is the difference between autologous and allogeneic stem cells?

Autologous stem cells are derived from patients themselves, which have perfect tissue compatibility, no need for matching, high utilization rate of transplanted cells and no rejection.

Allogeneic stem cells are derived from individuals other than patients and have low immunogenicity. Autologous stem cells are not recommended for people with infectious diseases, major genetic diseases or other health problems.

05

How can stem cells be used to treat diseases?

Cells are the basic unit of life. Human life is accompanied by the process of self-replication and differentiation of stem cells from birth to growth. The ability of stem cells to treat diseases mainly stems from their biological characteristics, which include:

The ability of long-term survival and continuous self-replication;

It can differentiate across different lines and germ layers, showing high plasticity;

And its chemical tendency, that is, homing effect, provides an important biological basis for cell therapy.

06

Is stem cell therapy risky?

Compared with conventional drug therapy, stem cell therapy is considered safer and has fewer side effects. But this does not mean that the risk is zero. Looking at stem cell therapy objectively, the following are some main risks of stem cell therapy:

Tumor development: If stem cells divide or differentiate into abnormal cells uncontrollably, it may lead to cancer. This mainly applies to embryonic or fetal stem cells, or reprogrammed stem cells, because the risk is based on their pluripotency.

Immune rejection: The body may regard foreign stem cells as a threat and attack them, leading to inflammation and injury. This is more likely to happen in hematopoietic stem cells (HSC).

Infection or complications related to invasive medical procedures: Stem cell therapy may lead to infection or complications related to invasive medical procedures.

Drug interaction: Stem cell therapy may have unpredictable interactions with other drugs taken by patients, which may lead to adverse drug interactions.

Unconfirmed or untested stem cell therapy: There is also the risk that unscrupulous practitioners provide unconfirmed or untested stem cell therapy, which may be unsafe or effective.

The effect of treatment is uncertain: patients should also realize that stem cell therapy does not guarantee a cure, and in some cases, it may not be effective at all. Stem cell therapy may not provide lasting results, and patients may need additional treatment.

It should be noted that these risks may be different due to individual differences, treatment methods, stem cell types and other factors. Before receiving stem cell therapy, patients should fully discuss these risks with doctors and weigh the potential benefits and risks of treatment.

07

What diseases can stem cell therapy treat?

Stem cell therapy is mainly used in the fields of treatment, health care and beauty, and it is also used to improve some refractory diseases.

Heart disease: Stem cells can regenerate damaged heart cells and maintain the health and vitality of the heart through a specific process of induced differentiation in the treatment of heart disease.

Prevention and treatment of Alzheimer’s disease: Injecting induced differentiated stem cells can replace aging brain cells and improve cognitive function.

Treatment of liver cirrhosis: generate liver cells through differentiation, and promote the regeneration and repair of liver cells.

Cancer treatment: Directionally differentiated stem cells can enhance the body’s immune function and help fight tumors.

Treatment of premature ovarian failure: Stem cell therapy can restore ovarian function, promote the repair of damaged tissues, improve ovarian microenvironment, enhance reproductive capacity, prevent follicular atresia and promote follicular renewal.

Male hypofunction: Stem cell therapy can repair the aging of reproductive system, improve sexual function, maintain the balance of sex hormones, reduce nocturia, relieve the symptoms of prostatic hyperplasia, and help prevent prostate hypertrophy and other problems.

Enhance muscle function: with the increase of age, muscle function weakens, strength and relaxation function decline, and the body is bloated. Stem cell therapy can improve muscle function, enhance strength, improve body shape and show youthfulness.

08

What is the effect of stem cell therapy?

Stem cell therapy can be carried out by systemic infusion or fixed-point intervention. Clinicians adopt appropriate cell types and treatment strategies according to patients’ health status and disease needs.

Because this treatment can directly intervene in the cause of disease, avoid other physical injuries that may be caused by drugs and surgery, and help regulate the sub-health state, the effect is usually not limited to treating diseases, but also improving the overall function.

09

Is there an age limit for stem cell transfusion?

Traditionally, some types of stem cell transplantation, such as allogeneic bone marrow transplantation, often have age restrictions, and it is usually recommended to be 50 years old or under 45 years old. However, with the progress of medical technology, this limitation is being broken.

For example, it has been reported that a 71-year-old patient successfully received autologous hematopoietic stem cell transplantation, and a 69-year-old woman also successfully received her son’s hematopoietic stem cell transplantation.

These cases show that under proper medical conditions and monitoring, elderly patients may also successfully receive stem cell transfusion therapy, which proves that the age limit is gradually relaxing.

10

What are the taboo populations of stem cells?

Patients with advanced malignant brain tumors, especially brain tumors;

Patients with shock or general failure with abnormal vital signs (requiring disease correction) and those who do not cooperate with the examination;

Patients with heart, lung, liver, kidney and other important organ dysfunction (multiple organ dysfunction syndrome);

Patients with dysfunction of coagulation mechanism;

Patients with severe local infection;

Patients with positive serological results (such as HIV, hepatitis B, syphilis, etc.);

People with high allergic constitution or severe allergic history;

People with nervous system diseases or diseases that have not been diagnosed;

This group is in a special situation and has uncontrollable risks, so it needs careful diagnosis and treatment.

Write it at the end

Stem cells have excellent regeneration and repair functions, and these abilities will gradually weaken with age. Therefore, it is an increasingly popular choice to store healthy stem cells as early as possible, which will provide the possibility for future health management and disease treatment.

The 21st century will be the era of cell therapy, and the application of stem cells and immune cells is expected to play an important role in clinical treatment.

However, at present, except for the mature clinical application of hematopoietic stem cell transplantation, other types of stem cell therapy are mostly in the research stage, and strictly designed clinical trials are needed to prove their clinical advantages, safety and effectiveness, which need further study.

Moreover, non-compliant and eager stem cell therapy and research not only threaten the safety of patients, but also hinder the improvement of stem cell therapy and its research level, which needs the attention of legal supervision, and patients with hope in stem cell therapy should also be alert to fraud and pay attention to its development and related policies and regulations.

Some dating software is still "undefended" for minors.

  Multiple social apps can still be used normally without "real-name authentication". Insiders suggest that the youth mode should be turned on by default.

  Recently, many netizens found and reported that some dating software is not strict with the use of minors. The Beijing Youth Daily reporter found that when using multiple strangers’ dating software, there is no need for real-name authentication, and minors can use these strangers’ social software "unimpeded". It is particularly noteworthy that in terms of function, there is no difference between unauthenticated accounts and other accounts, and accounts without real-name authentication can also purchase adult products at will. In this regard, many people in the industry have suggested that the youth mode can be turned on by default when the user does not log in with an ID card.

  find

  Multiple social App users can also be rewarded without real-name authentication.

  The reporter of Beiqing Daily recently found that many social apps, such as soul, Detective, Momo, etc., can be used normally by simply choosing to log in with WeChat or mobile phone number without "real-name authentication".

  These platforms all suggest that users must be over 18 years old when registering. For example, after soul registers, users need to choose the date of birth, but users can enter the interface without hindrance by filling in a date over 18 years old at will. Among them, soul needs to use a virtual avatar, and exploration and Momo need to add a real and clear avatar.

  In the process of use, the above App will send a pop-up window in teenager mode to the user. The reporter of Beiqing Daily noticed that the youth mode entering Soul needs real-name authentication, and people’s faces will be dynamically recognized during the authentication process. After the tester enters his real name information, he can’t enter the teenager mode again. The teenage mode of exploring and momo is to set the password directly.

  In view of the fact that it can be used normally without real-name authentication, Momo customer service responded: "Some functions need real-name use." When asked which functions will be affected by not having a real name, the customer service did not give a positive answer. In addition, regarding whether the real name will restrict consumption, the customer service said: "No real name will not restrict consumption."

  When using the live reward function of Detective and Momo, even the account without real-name authentication will automatically jump to WeChat or Alipay.

  In terms of recharge, none of the above three softwares has relevant restrictions or secondary verification for minors. And there is no real name account and unlimited consumption, which can recharge the highest amount of soul coins, exploration coins, momo coins and VIP recharge.

  experience

  Push content is undifferentiated, making friends and shopping are not affected.

  The reporter of Beiqing Daily used an account without real-name authentication on a dating software, and marked "the second day" in the introduction. After searching for keywords such as "making friends in junior high school", "sexy underwear" and "adult products" on the home page, a lot of related push content appeared. The purchase of goods can automatically jump to WeChat or Alipay. In other words, if minors are not authenticated in this platform, it will not affect their use.

  After several keyword searches, Beiqing Daily reporter used the test account to open the above-mentioned dating software again, and the homepage push also became the corresponding content related to keywords, in which minor dating also appeared directly and many times. In the shopping column, most of the products pushed also meet the previous keywords.

  In the actual measurement, the reporter of Beiqing Daily also found that there are multiple video platforms in the youth protection mode, and the platforms will impose restrictions on young users in terms of content, usage duration and consumption.

  For example, the daily use time should not exceed 40 minutes, and it is forbidden to use the software from the evening to the next morning, and it is impossible to open or watch the live broadcast, reward, recharge, cash withdrawal and so on. For example, a survey shows that in the youth mode, except for the functions of mobile phone recharge and city service, other functions of life service, transportation and shopping consumption are all disabled, while the functions of financial management are directly hidden. Aauto Quicker and Tik Tok, short video applications, banned teenagers from watching live broadcasts, which fundamentally prevented the risk of teenagers’ recharge and reward. Tik Tok also closed Tik Tok Mall. Video platforms Iqiyi, Tencent, Youku and Mango TV have closed the membership center and all other consumption channels such as financial welfare and games. Bilibili has also closed consumer operations such as membership purchase and top-up rewards.

  suggestion

  Directly open the youth mode for the unauthenticated netizen platform.

  In response to the measured results of the reporter of Beiqing Daily, Professor Shang Jianhui, deputy dean of the School of Journalism and Communication of Hebei University, believes that the platform practice that has not yet imposed restrictions on young users does not conform to the norms. "According to the explicit requirements of the Regulations on the Protection of Minors’ Network (Draft for Comment) and the Regulations on the Protection of Children’s Personal Information Network, the network platform should formulate special rules and user agreements for the protection of children’s personal information. Therefore, this practice of the platform should be improved, otherwise it may cause harm such as premature maturity of children and deception of the network. "

  Professor Shang suggested how to improve the platform’s protection measures for minors. "At present, there are some voices in academic circles. The index system of minors’ network protection includes 19 indicators in six dimensions, including information prompt, technical protection, anti-addiction (comprehensive) management, emergency complaint and reporting mechanism, privacy and personal information protection system, scientific popularization and publicity and education."

  "Technical protection, information tips, scientific popularization and publicity and education are the weak links in the protection of minors on the Internet platform. The platform should first strengthen technical security protection and realize standardized management of the platform; Secondly, construct an omni-directional information prompt matrix to optimize the use environment of minors; Furthermore, practice the concept of multi-knowledge inclusiveness and do a good job in popular science and publicity and education; Finally, improve the youth model and enrich the content pool for minors. " Professor Shang said.

  Some operators who did not want to be named told the reporter of Beiqing Daily that "registering with a mobile phone number does not mean real-name authentication. Operators will not synchronize all users’ personal information to all platforms at will. It is not excluded that operators cooperate with some larger platforms to authorize the platforms to identify information through mobile phone numbers, but only if both parties sign an agreement to ensure the other party’s safe storage and standardized use of personal information. Therefore, it cannot be said that registering with a real-name mobile phone number is equivalent to real-name authentication. "

  Earlier, Jiang Yaodong, member of Chinese People’s Political Consultative Conference and former vice president of China University of Mining and Technology (Beijing), also suggested that "for users who have not been authenticated, the platform can default the user to enter the youth mode, which can protect minors from browsing age-appropriate content to the greatest extent."

  interlinkage

  According to public data, in 2021, the number of underage netizens in China reached 191 million, and the Internet penetration rate of minors reached 96.8%. According to a survey released by Beijing Internet Court, from June 2022 to May 2023, Beijing Internet Court accepted a total of 143 civil disputes involving minors, and the number of cases increased year by year, with game recharge and live rewards accounting for the largest proportion. Among them, the phenomenon that minors involved in litigation evade family supervision and anti-addiction measures is more prominent, and most minors evade family supervision and platform authentication measures. At the same time, minors are easily influenced by bad information. Some minors use the Internet to browse pornographic, bloody and violent bad content, and some minors are influenced by the online war and the "network water army" and learn to imitate bad online behavior.

Seven experts called for paying attention to supporting the development of rice oil industry and improving the self-sufficiency rate of edible oil in China

  Harbin, China Economic Net, July 6 (Reporter Wu Xuan) One of the reasons that have restricted the development of rice oil in China for many years is that rice bran is easy to rancidity and difficult to preserve. Now this technical bottleneck has made a new breakthrough. Yihai Kerry, the parent company of Arowana, has created a brand-new rice oil production model of decentralized preservation, centralized collection and centralized refining. "The remaining problem now is to study the policies and measures to support the development of rice bran oil industry." Wang Ruiyuan, chief expert of China Cereals and Oils Association and president of the Oil Branch of China Cereals and Oils Association, called on the "Seminar on the Integrated Development of Rice Circular Economy Industry Chain and Rice Oil Industry" held in Harbin on July 6, hoping that the state would pay more attention to the rice oil industry and give support in policies, funds and taxes, so as to accelerate the development of rice oil industry and improve the self-sufficiency rate of edible oil in China. Experts attending the meeting actively put forward suggestions and suggestions on exploring a new model of rice circular economy industrial chain, strengthening the implementation of China’s rice oil series standards, and improving rice oil production technology.

  Rice oil, with its balanced nutritional proportion, has the reputation of "golden rice" and is a healthy edible oil recommended by the World Health Organization. In Japan, a big rice producer, the utilization rate of rice bran is nearly 100%. Rice oil has become the designated oil for nutritious lunches of primary and secondary school students in Japan. The production of rice oil in China began in the 1950s, and in the 1970s and 1980s, the work of increasing oil production, represented by the promotion of rice bran and corn germ oil extraction, was carried out nationwide, with remarkable results. However, due to various reasons, the utilization rate of rice bran in China is less than 20%. Most rice bran is used as feed, or even discarded as waste, which is a sad waste of resources. The data shows that the self-sufficiency rate of edible oil in China in 2015-2016 was 32.3%.

  Experts believe that as the largest country in rice production and consumption, the nutritional value and resource benefit of rice bran by-products in China have not been fully exerted. If the rice bran, a by-product of rice with an annual output of 200 million tons in China, is used to extract oil, it is equivalent to about 13 million tons of soybean oil, which is equivalent to saving 110 million mu of soybean cultivated land for the country, which will greatly improve the self-sufficiency rate of edible oil in China. Developing rice oil industry is one of the effective ways to improve the self-sufficiency rate of edible oil in China without competing with fertile land. Experts attending the meeting said that actively developing rice oil industry in China is a necessary move for the supply-side structural reform of edible oil processing industry.

  At present, there are three main reasons that restrict the development of rice oil in China: first, the rice processing enterprises in China are small and scattered, and it is difficult to concentrate rice bran; Second, rice bran is prone to rancidity and deterioration, and the preservation technology is not easy to solve; Third, the policies and measures to support the development of rice oil industry are not strong enough.

  At present, the technical bottleneck has been broken. According to reports, Yihai Kerry, the parent company of Arowana, has created a brand-new production mode of rice oil with decentralized preservation, centralized extraction and centralized refining. It has used a series of advanced production technologies such as 6-hour expansion preservation, low-temperature extraction and internationally advanced green enzymatic degumming, so that natural cereal active nutrients such as oryzanol, vitamins and sterols can be retained to the greatest extent.

  Rice bran oil production is an important link of rice circular economy in Yihai Kerry. Since entering the field of rice processing in 2006, Yihai Kerry has started to research and develop a new model of comprehensive utilization of rice. In the past ten years, the accumulated investment has reached several billion yuan, and gradually built a new circular industry model of "order planting-intensive processing-product brand-name-making-comprehensive utilization of by-products-high-tech product research and development". Through the order base, the purity of rice varieties and the quality of arowana rice are guaranteed; At the same time, independently research and develop rice bran preservation technology to improve the yield and quality of arowana rice oil. Fatty acids, rice bran wax, rice bran fat, oryzanol, ferulic acid and other high value-added products extracted from rice bran oil by-products and rice bran meal are widely used in food special oils, grease chemicals, cosmetics and other industries; At the same time, rice husk combustion was realized to generate electricity, and activated carbon and white carbon were prepared from rice husk ash. At present, the rice husk silica produced by Yihai Kerry has achieved cross-industry cooperation with tire production giants and is being popularized and applied worldwide.

  Yihai Kerry’s rice circular economy model has truly realized the transformation from the traditional extensive rice processing model to the "eat dry and squeeze clean" processing model with intensive processing and high-efficiency and energy-saving utilization of by-products, which has increased farmers’ rice planting income and increased the added value of rice products, and realized the integration of order agriculture, intensive processing of agricultural products, brand product sales and service. Nowadays, the utilization rate of rice bran in Yihai Kerry rice circular economy model reaches 60-70%, which is much higher than the average ratio of rice bran utilization rate of less than 20% in the whole industry.

  Jiang Yuanrong, a researcher at Fengyi (Shanghai) Biotechnology R&D Center Co., Ltd., said that this model can fully develop and utilize the economic value of rice. If it can be replicated and promoted throughout the country, its economic and social benefits will be considerable.

  In April 2017, Yihai (Jiamusi) Cereals and Oils Industry Co., Ltd., a subsidiary of Yihai Kerry, was officially approved by the National Development and Reform Commission as the "National Pilot Unit for Standardization of Rice Processing Circular Economy", which is the only pilot enterprise in the rice processing industry in China, marking that this global leading rice circular economy model has been incorporated into the national green development plan. "Perfecting and popularizing it will be beneficial to the sustainable development of rice processing and rice oil industry in China." Zhang Guifeng, chairman of China Cereals and Oils Society, fully affirmed Yihai Kerry’s active exploration and practice in the industrial chain mode of rice circular economy.

  On October 25th, 2016, at the 3rd ICRBO- International Rice Oil Conference held in Tokyo, Japan, Arowana rice oil from China won unanimous praise from oil experts from China, Japan, India, Thailand and Vietnam, and won the only "International Rice Oil Quality Award" selected by the Conference. The award indicates that China’s independently innovated rice oil production technology has completely surpassed Japanese and advanced the international level.

  The 13th Five-Year Development Plan of Grain and Oil Processing Industry formulated by the State Grain Administration proposes to "actively develop rice bran oil", and to "achieve the utilization rate of by-products such as rice bran above 50%" by 2020, and cultivate a number of leading enterprises in the integration of grain and oil processing industry. At this stage, increasing policy support has become a booster to accelerate the integration and development of rice, oil and three industries in China.

  The meeting was jointly sponsored by the Oil Branch of China Cereals and Oils Association, the Technical Committee of Oils and Oils of National Cereals and Oils Standardization Technical Committee, and undertaken by Fengyi (Shanghai) Biotechnology R&D Center Co., Ltd. The meeting aims to further promote the development of China’s rice oil industry and deepen the transformation and upgrading of China’s grain processing industry. 

Regenerative Medicine Breakthrough China Scientists Induce Human totipotent Stem Cells.

  Recently, researchers from China Academy of Sciences, Shenzhen Huada Institute of Life Sciences and other institutions have cultivated human pluripotent stem cells in a state similar to that of fertilized eggs developing for three days through somatic cell induction. This is the "youngest" human cell cultured in vitro in the world at present, and it is another subversive breakthrough in the field of regenerative medicine after scientists successfully induced human pluripotent stem cells. Related research results were published in the international academic journal Nature in the early morning of March 22nd, Beijing time.

  It is understood that researchers have developed a non-transgenic, fast and controllable "cocktail" cell reprogramming method, which can transform human pluripotent stem cells into totipotent 8-cell embryonic-like cells, that is, totipotent stem cells equivalent to the three-day development of fertilized eggs. This achievement will help to realize the in vitro regeneration of human organs in the future, and it is of great significance to solve the problems of organ shortage, allograft and xenotransplantation rejection.

  In 2012, the Nobel Prize in Physiology or Medicine was awarded to shinya yamanaka, a Japanese scientist who successfully induced mature somatic cells into pluripotent stem cells in blastocyst stage. The cells in human blastocyst stage are fertilized eggs developing 5-mdash; In the state of 6 days, its ability to further develop is limited.

  However, this study has made a big step forward in this field, and for the first time, embryonic cells with fertilized eggs divided for only 3 days were obtained. In the early stage of fertilized egg development, great changes have taken place every day, and it is these 2-mdash; In 3 days, scientists obtained human 8-cell embryonic-like totipotent stem cells through in vitro induction for the first time. This is the "youngest" human cell induced in vitro so far, and it has very strong development potential. This study will also help to unlock the key to the early development of human embryos.

  According to reports, these totipotent 8-cell embryonic-like cells reconstructed the embryonic state of fertilized eggs after only three times of division. Compared with pluripotent stem cells in the past, these cells can differentiate into placental tissues and may develop into more mature body tissues.

  "This progress is also a model of the combination of regenerative medicine and single cell sequencing technology." Dr. Liu Longqi from Shenzhen Huada Institute of Life Sciences, one of the authors of the paper, said, "The efficient identification and mechanism analysis of cells or tissues obtained by stem cell technology in vitro or in vivo will greatly accelerate the development of regenerative medicine."

  This is the first time that researchers have "transformed" human pluripotent stem cells into pluripotent embryonic cells in a real sense, so that people can reverse the "adult" version of cells into "infant" versions with more possibilities. At the same time, because the totipotent cells obtained this time are closer to the original state of early embryos, if they are used in regenerative medicine, the cultivated organs will be closer to the state of real organs, which is more conducive to transplantation.

  This breakthrough is due to the progress of single cell sequencing technology. In the past, researchers may have to process and culture thousands of cells, and the probability of success is less than 10%. Nowadays, based on the single-cell library sequencing platform (DNBelab C4) independently developed by Huada University, combined with the DNBSEQ sequencing technology created by Huada Zhizhi, scientists can conduct multidimensional single-cell analysis with high sensitivity and accuracy, quickly obtain cells with important development potential, and study the development direction of these cells.

  In this study, the research team also classified the induced pluripotent stem cells and injected them into mice for further development, and then used the single cell sequencing technology of Huada to conduct large-scale cell map analysis. Finally, the researchers confirmed that the experimental totipotent stem cells were highly similar to human 8-cell embryonic cells, which proved the totipotency of the cells. This provides a scientific basis for organ culture using patients’ own cells in the future and for organ transplantation and replacement.

  The research was led by China Academy of Sciences and Shenzhen Huada Institute of Life Sciences, with the participation of several research teams including Cambridge University, Jilin University and rajshahi University. This study has passed the ethical review and strictly followed the corresponding laws and regulations and ethical standards.

Many places in the country have successively adjusted the endurance category of the senior high school entrance examination to be exempted or selected.

  On March 10th, the Education Bureau of Hengyang City, Hunan Province issued a notice saying that after comprehensive research, it was decided to adjust the items and time of the physical education examination of Hengyang junior high school academic level examination in 2023: the middle and long-distance race (1000m for men and 800m for women) in the basic test items was adjusted from compulsory examination to exemption examination, and all candidates in this project were given full marks.

  This year, many places in the country have successively adjusted the plans for the senior high school entrance examination for physical education, and some places have adjusted endurance events such as long-distance running and swimming as optional items.

  Among them, on March 8, Hangzhou Education Bureau released the latest adjustment plan for the 2023 senior high school entrance examination physical examination. So far, 11 districts and cities in Zhejiang Province have officially announced the sports programs for this year’s senior high school entrance examination, and the 1000-meter running (boys) /800-meter running (girls) projects have been adjusted to "can run or not".

  The Paper noted that Lishui Education Bureau mentioned in answering questions from the public that candidates infected with novel coronavirus should carefully apply for physical endurance events such as 1000m (male) or 800m (female), and candidates who apply for such events should do a good job in personal health risk assessment.

  Lishui City Education Bureau also reminded that candidates who have been infected with novel coronavirus and other special physique should pay attention to the recovery training of physical skills and gradually increase the difficulty intensity when preparing for the exam. Warm-up exercises should be done before training, physical condition should be paid attention to during training, and rest should be paid attention to in time after training. If necessary, give feedback to the teacher or parents about your physical condition. If you have difficulty breathing, abnormal heart rate or excessive fatigue, you should consult a professional doctor in time.

  In Ji ‘an, Jiangxi Province, the notice issued by the Ji ‘an Municipal Education and Sports Bureau on March 6 stated that in 2023, there will be no compulsory items in the entrance examination for junior and middle school graduates, and the compulsory items (1000m for men/800m for women) will be adjusted to optional items. Candidates choose two items from five selected items for testing.

  The Education and Sports Bureau of Ji ‘an said that all localities should fully understand the background and significance of the adjustment of this year’s physical examination items in the province, that is, from three items of the original examination to two items of the examination, and from the original compulsory examination items to optional examination items, so as to take effective measures to prevent major risks.

  In addition, the "Notice on Doing a Good Job in the Physical Education Examination for Junior and Middle School Graduates in 2023" issued earlier by the Guangdong Provincial Department of Education also adjusted the compulsory items (men’s 1000 meters/women’s 800 meters and swimming) in the unified test project to optional items. The "Notice" pointed out that in view of the current epidemic situation in Guangdong Province and the physical health status of students, in order to effectively ensure the scientific, safe and smooth progress of the physical education examination for junior and middle school graduates in 2023, after in-depth analysis, comprehensive judgment and careful consideration, it was decided to make corresponding adjustments to the physical education entrance examination in Guangdong Province in 2023.

Keep enough cars and prepare enough people to go all out to ensure the express delivery "Spring Festival travel rush"

  CCTV News:Every year before the Spring Festival, it is the peak season for all kinds of express delivery. Since Spring Festival travel rush started on January 7th, the daily postal express delivery volume has been over 300 million pieces, with a peak of over 400 million pieces. What changes have been made to the express delivery capacity that will be tight in previous years? Can the express delivery business be guaranteed during the holidays? Is the way home by express delivery smooth?

  At 6: 30 in the morning, at this express outlet in Zhongguancun, the person in charge, Lei Liping, simply said a few words, and the express buddy immediately threw himself into the sorting work.

  As the nearest express terminal service point to customers, from 4: 00 in the morning, there are trucks coming into the field one after another, and express parcels sent from all over the country to nearby areas are pulled from the transit point. The express parcels waiting to be sorted and delivered quickly piled up a hill.

  "hurry up! Hurry up! " This is the word that reporters hear the most frequently at the scene. Lei Liping told reporters that near the Spring Festival, the peak of express delivery has been ushered in recent days. Because most of them are fresh food, gifts and other new year’s goods, in order to ensure the timeliness, the express delivered from all over the country in the morning should be delivered to customers before noon. Nearly 50 courier brothers in this outlet have to arrive at their posts before 6: 30 in the morning, and breakfast can only be solved.

  Less than 8 o’clock, the five express parcels sent in the morning have been sorted.

  Go all out to ensure the express delivery "Spring Festival travel rush", the grass-roots outlets at the end of delivery operate efficiently, and the circulation at the end is smooth. Then, what is the transition in express delivery with a wider business scope?

  The reporter saw in a courier transfer near the Capital Airport that dozens of unloading ports were full of trucks. On the other hand, there are long queues of vehicles waiting for unloading.

  Handling 600,000 peak packages per day is definitely not possible by manpower alone. The reporter saw at the scene that the automatic sorting equipment helped a lot. After unloading, these parcels were transported to the automatic sorting machine, and more than 600 sorting ports could be automatically divided into different parcel bags according to the area codes on the face sheet.

  Save enough cars and people. In order to cope with the peak of express delivery during the Spring Festival, recently, many express delivery companies have proposed "no fighting during the Spring Festival" to ensure the smooth flow of express logistics.

  In Beijing Xinfadi Fruit Wholesale Market, Wei Dongwen, who is in charge of contacting the truck service for merchants, asked about the shipment of merchants and contacted the truck by phone.

  Wei Dongwen told reporters that people have been going home for the New Year these days, but they have also left enough manpower to ensure the delivery needs of customers. During the Spring Festival, there are still many courier brothers who are ready to stick to their posts to ensure that the courier service during the festival is not interrupted.

  Shi Jianting and Zhang Huanrong, couples from Linfen, Shanxi, have stayed at the delivery line for four consecutive Spring Festival. The couple planned that after the 14th day of the first month, the list was running out, and they would go home at the wrong peak.

  The reporter learned in the interview that a number of measures have been introduced in various places to actively respond to the express delivery demand during the holiday season. Some express delivery companies start the "night delivery" mode, extend the delivery time at night, and give priority to timely delivery of drugs, epidemic prevention materials and food. Jiangsu issued 35 million yuan of government subsidies for the postal express delivery industry to stabilize and return to work, helping the postal express delivery industry to accelerate its recovery. In Luzhou, Sichuan, the bus driver undertakes the task of delivering the express delivery. After receiving the express delivery from the postal transport vehicle, the bus driver sorts and delivers the express delivery to the Jintong Post Express Station in each village to get through the "last mile" of the parcel entering the village.

Improve the implementation and supervision system of the Constitution (study and implement the spirit of the Fourth Plenary Session of the 18th CPC Central Committee)

  The Fourth Plenary Session of the 18th CPC Central Committee is a very important meeting held at the decisive stage of building a well-off society in an all-round way. The plenary session adopted "the Central Committee of the Communist Party of China’s Decision on Several Major Issues of Comprehensively Promoting the Rule of Law" (hereinafter referred to as the "Decision"), which made a top-level design and strategic deployment for comprehensively promoting the rule of law, clearly outlined the grand blueprint for the construction of China ruled by law, and specifically defined the road map and task book for comprehensively promoting the rule of law in various fields. It is a landmark programmatic document. The "Decision" makes an incisive exposition on safeguarding the authority of the Constitution, strengthening the implementation of the Constitution, and carrying forward the spirit of the Constitution, and puts forward clear requirements, which will surely raise the full implementation of the Constitution to a new level.

  1. The Constitution is the fundamental law of the country, and it is the general charter for governing the country and safeguarding the country.

  The "Decision" pointed out: "The Constitution is a concentrated expression of the will of the party and the people and a fundamental law formed through scientific and democratic procedures." We should fully understand the important position and role of the Constitution in the political and social life of the country, and earnestly enhance the consciousness and firmness of observing and safeguarding the Constitution.

  The constitution is the concentrated expression of the common will of the party and the people. China’s Constitution is closely linked with the arduous struggle and brilliant achievements made by the Party and the people, the road ahead opened by the Party and the people and the valuable experience accumulated. As early as 1940, Comrade Mao Zedong pointed out that "after the success of the revolution had democratic facts, a fundamental law was promulgated to recognize it, which is the Constitution". Since the founding of New China, especially since the reform and opening up, the major principles and policies determined by the Party’s previous congresses have been fully reflected in the Constitution. For example, the 1982 Constitution and its four subsequent amendments timely wrote the Party’s major theoretical achievements such as Deng Xiaoping Theory, Theory of Three Represents’s Important Thought, Persistence in Reform and Opening-up, Primary Stage of Socialism, Socialist Market Economy, Ruling the Country by Law and Builders of Socialist Cause into the Constitution. The current constitution, in the form of the fundamental law of the country, establishes the development achievements of Socialism with Chinese characteristics’s road, theoretical system and system, reflects the common will and fundamental interests of the people of all ethnic groups in China, and is a high degree of unity of the party’s ideas and the people’s will. Safeguarding the legal authority of the Constitution means safeguarding the authority of the common will of the Party and the people, safeguarding the dignity of the constitutional law means safeguarding the dignity of the common will of the Party and the people, and ensuring the implementation of the constitutional law means ensuring the realization of the common will of the Party and the people. It is necessary to fully understand that only by earnestly respecting and effectively implementing the Constitution can the development of the cause of the party and the state and the happiness and well-being of the people be fundamentally guaranteed by law.

  Constitution is a direct reflection of people’s democratic rights and wishes. The "Decision" pointed out that "the CPC Central Committee proposed constitutional amendments to the National People’s Congress and carried out constitutional amendments in accordance with the procedures stipulated in the Constitution." This fully embodies the organic unity of the party’s leadership, the people being the masters of the country and governing the country according to law, and highlights the distinctive characteristics of China’s socialist democracy. In the process of formulating and amending the constitution of our country, democracy is fully promoted, and procedures are strictly followed to ensure the extensive participation and high recognition of the whole party and society. When China’s first constitution was formulated in 1954, more than 8,000 representatives from state organs, Chinese People’s Political Consultative Conference, democratic parties, people’s organizations and all walks of life were organized to participate in the discussion, and more than 6,000 opinions were put forward after sorting out. In the subsequent national discussion, 150 million people participated, and more than 1 million amendments and suggestions were received from all over the country. In 1982, the draft amendment to the current constitution was fully discussed by the whole people for four months, and the opinions and suggestions from all sides inside and outside the party were widely solicited for the next four amendments. It can be said that the formation and development of the Constitution is a process in which the people directly exercise their democratic rights and reflect their democratic will, and it is also a process in which the wisdom and consensus of the whole party and the people of the whole country are highly condensed. It is necessary to fully understand that the constitution is formed and developed through scientific and democratic procedures, and it is the most extensive and true embodiment of socialist democracy in China.

  The constitution is the highest code of conduct that the whole society must strictly abide by. Since the reform and opening up, China’s current constitution, with its supreme legal status and strong legal power, has guaranteed the people to be masters of their own affairs, promoted reform and opening up and socialist modernization, promoted the process of a socialist country ruled by law, and safeguarded national unity, national unity and social stability. Practice has proved that this is a good constitution that conforms to the national conditions, reality and the requirements of the development of the times. The Decision emphasizes that "all organizations and individuals must respect the legal authority of the Constitution" and that "people of all ethnic groups, all state organs and armed forces, all political parties, all social organizations, and all enterprises and institutions in China must take the Constitution as the fundamental criterion for their activities, and have the responsibility to safeguard the dignity of the Constitution and ensure its implementation", which further demonstrates the clear attitude and firm determination of the CPC Central Committee with the Supreme Leader Comrade as the general secretary in upholding the rule of law and governing the country according to the Constitution, and establishes the Constitution in the national governance system and institutions. We must always uphold the supremacy of the Constitution and fully understand that the Constitution, as the fundamental law to ensure the prosperity and long-term stability of the Party and the country, has the highest authority and must be fully respected and resolutely safeguarded.

  Two, the life of the constitution lies in the implementation, and the authority of the constitution lies in the implementation.

  The strength of the constitution is not only due to its lofty status, but also due to its effective implementation. Otherwise, the constitution can only stay at the level of "political declaration" and text. The "Decision" puts forward clear requirements for strengthening the implementation of the Constitution. We must persistently strengthen the implementation of the Constitution as the primary task and basic work of building a socialist country ruled by law, and pay close attention to it to ensure that the leading role of the Constitution in national governance and social governance is fully exerted.

  Conscientiously fulfill the constitutional mission and work together for the prosperity of the country, the rejuvenation of the nation and the happiness of the people. The Constitution confirms the brilliant achievements made by our Party in leading the people’s long-term struggle, stipulates the nature and fundamental system of state power under the people’s democratic dictatorship, and defines the fundamental task and general goal of the country’s future construction and development. It is the highest embodiment of the central work, basic principles, major principles and important policies of the Party and the country in the new period. We should bravely shoulder the historical heavy responsibility and sacred mission entrusted by the Constitution, persist in emancipating our minds, comprehensively deepen reform, make overall plans to promote the construction of socialist economic, political, cultural, social and ecological civilization, and strive to achieve the goal of "two hundred years" and the great rejuvenation of the Chinese dream by the Chinese nation. We must adhere to the constitutional concept that all state power belongs to the people, adapt to the new requirements of promoting economic and social development and expanding people’s democracy, and mobilize and organize the people to manage state and social affairs, economic and cultural undertakings through various channels and forms in accordance with the provisions of the Constitution and laws, so as to jointly build, enjoy and develop together, so as to maximize the realization and maintenance of the people’s yearning for a better life.

  Always abide by the constitutional principles and adhere to equality before the law. Equality is the basic attribute of socialist law. China’s Constitution stipulates: "All citizens of People’s Republic of China (PRC) are equal before the law." All citizens in China are equal in the application of laws, regardless of nationality, sex, occupation, family background, religious belief, education level and property status. The "Decision" once again reaffirms this important principle, emphasizing that any organization or individual "must operate within the scope of the constitutional law, must exercise power or rights, perform duties or obligations in accordance with the constitutional law, and must not have privileges beyond the constitutional law". It is necessary to safeguard the unity, dignity and authority of the national legal system and effectively ensure the effective implementation of constitutional laws. No one will be allowed to substitute words for laws, suppress laws and bending the law with power under any pretext or in any form. It is necessary to focus on standardizing and restraining public power, strengthen supervision, make sure that the right must be held accountable, the right to use it is supervised, and those who violate the law must be investigated, and resolutely correct those who fail to abide by the law, enforce the law lax, and fail to investigate the law.

  Vigorously carry forward the spirit of the constitution, and effectively embody and run through the whole process of governing the country according to law. The core of the spirit of the Constitution is that the people are the masters of the country. The "Decision" emphasizes that it is necessary to "improve the socialist legal system with Chinese characteristics with the Constitution as the core" and "make every legislation conform to the spirit of the Constitution, reflect the will of the people and win the support of the people". This is an important premise and foundation for the correct and unified implementation of the Constitution. By the end of 2013, there were 243 effective laws, 731 administrative regulations and 9347 local regulations (including autonomous regulations and separate regulations) in China. It is important to keep these laws and regulations consistent with the spirit of the Constitution. The basic principles and systems established by the Constitution, the basic spirit of regulating state power and realizing citizens’ rights, etc., need to be refined through laws, regulations and other normative documents, and more importantly, the state administrative organs, judicial organs, procuratorial organs, all social organizations and all citizens need to consciously abide by them to implement them. It is necessary to regard the Constitution as the highest legal norm, strictly follow the clear statutory authority and requirements of the Constitution, scientifically legislate, strictly enforce the law, justly administer justice, and abide by the law by the whole people, so that the spirit of the Constitution can be fully reflected in all aspects of the rule of law.

  Effectively safeguard the authority of the Constitution and resolutely investigate and correct all acts that violate the Constitution. It is the basic requirement of governing the country according to law and an important embodiment of the implementation of the constitution to abide by the law and prosecute those who violate the law. The current constitution meets the needs of building a well-off society in an all-round way and realizing the Chinese nation’s great rejuvenation of the Chinese dream, and its core position in the socialist legal system with Chinese characteristics has been formed. However, in real life, some departments just regard the Constitution as a supreme law. Many people think that the Constitution has little to do with ordinary people, and violations of the Constitution occur from time to time. In view of these problems in the implementation of the Constitution, the Decision emphasizes that "all acts that violate the Constitution must be investigated and corrected". It is necessary to formulate and improve the system of investigating the violation of the constitution, make clear provisions on the constitutive requirements, responsibilities, measures and procedures of investigating the violation of the constitution and strictly implement them, so that violations of the constitution can be stopped and corrected in time and the supreme authority of the constitution can be respected and safeguarded.

  Adhere to the party’s leadership and unify the party’s leading the people in formulating and implementing constitutional laws with the party’s adherence to activities within the scope of constitutional laws. This is a profound summary of our party’s experience in governing the country, a deepening understanding of our party’s ruling laws, a fundamental embodiment of constitutional principles with people’s sovereignty, basic human rights, power restriction and socialist rule of law as the main contents, and the key to the implementation of the constitution. Our party leads the people to formulate the constitution, and leads the people to abide by and implement it. To govern the country according to law, we must first govern the country according to the constitution; The key to governing according to law is to govern according to the constitution. To strengthen the implementation of the Constitution, we must always adhere to the leading core role of the Party in taking the overall situation into account and coordinating all parties, adhere to the organic connection between the internal laws and regulations of the Party and constitutional laws, be good at making the Party’s ideas become the will of the state through legal procedures, be good at making the candidates recommended by the Party organizations become the leaders of state organs through legal procedures, be good at implementing the Party’s leadership over the country and society through state organs, and be good at using the principle of democratic centralism to safeguard the central authority and the unity of the whole party and the whole country.

  Three, improve the supervision mechanism and procedures for the implementation of the Constitution, and effectively enhance the effectiveness of constitutional supervision.

  Constitutional supervision is an important institutional form to ensure the implementation of the constitution and safeguard its authority and dignity. The implementation of the constitution cannot be separated from the constitutional supervision. Since the promulgation and implementation of the 1954 Constitution, especially the 1982 Constitution, China has continuously explored and gradually established a constitutional supervision system with China characteristics. Promoting the rule of law in an all-round way and strengthening the implementation of the constitution have put forward new and higher requirements for constitutional supervision.

  Improve the constitutional supervision system of the National People’s Congress and its Standing Committee. China’s Constitution stipulates that the National People’s Congress and its Standing Committee are responsible for supervising the implementation of the Constitution. This reflects the system design that the National People’s Congress is the highest organ of state power and exercises state power on behalf of the people. Practice has proved that it conforms to China’s national conditions. The "Decision" emphasizes "improving the constitutional supervision system of the NPC and its Standing Committee", which not only highlights that the NPC and its Standing Committee have the highest constitutional supervision power, but also points out the direction of efforts to promote the institutionalization of constitutional supervision. It is necessary to improve the supervision mechanism and procedures, further clarify the object, scope and methods of constitutional supervision by the National People’s Congress and its Standing Committee, and make the principle requirements specific and procedural, so as to make the constitutional supervision more standardized and effective.

  Give full play to the role of constitutional interpretation. According to the spirit of the Constitution, it is very important to explain the contents, meanings and boundaries of the Constitution, so as to ensure and supervise the full implementation of the Constitution. In the face of the complicated international situation and arduous domestic tasks, especially in the decisive stage of building a well-off society in an all-round way, it is necessary to pay attention to the use of constitutional interpretation and strengthen the function and effectiveness of constitutional supervision to solve the new situations and problems faced by reform and development according to law and safeguard national unity, national unity and social stability. In order to promote the concretization and institutionalization of constitutional interpretation, the "Decision" emphasizes "improving the procedural mechanism of constitutional interpretation". It is necessary to establish and improve the system of constitutional interpretation, clarify the conditions for submitting constitutional interpretation, the initiation and acceptance of requests for constitutional interpretation, the deliberation, adoption and publication of constitutional interpretation cases, ensure the implementation of constitutional interpretation, complement the advantages of constitutional amendment, and advance with legal interpretation, so that our constitution can keep pace with the times and keep pace with the times on the basis of maintaining stability and authority.

  Strengthen the record review system and capacity building. It is an important content and link of constitutional supervision to record and review laws, administrative regulations and local regulations. According to statistics, by the end of 2013, the National People’s Congress Standing Committee (NPCSC) had received a total of 502 administrative regulations, 22,253 local regulations (including autonomous regulations and separate regulations) and 189 judicial interpretations. For the problems found in the review that are inconsistent with the constitutional laws, the enacting organs have been urged to amend or abolish them. The "Decision" emphasizes strengthening the record review system and capacity building, including all normative documents in the scope of record review, revoking and correcting unconstitutional and illegal normative documents according to law, and prohibiting local governments from issuing documents with legislative nature. It is necessary to improve the filing and review mechanism, improve the execution and binding force of the system, strengthen the cooperation between legislative supervision institutions, establish and improve the coordination and communication mechanism, effectively improve the filing and review ability, enhance the actual efficiency of filing and review, and safeguard the unity of the Constitution and the law.

  Guide all sectors of society to actively participate in constitutional supervision. All power in our country belongs to the people, and every citizen has the responsibility of consciously respecting and maintaining the constitution itself, as well as the right and obligation to participate in supervision. According to statistics, since 2004, there have been 1,137 censorship suggestions put forward by citizens and organizations, of which 475 are within the scope of filing and censorship in the National People’s Congress Standing Committee (NPCSC). It is necessary to give full play to the important role of socialist deliberative democracy in constitutional supervision, pay attention to the democratic supervision role of the CPPCC and the United front, organize and guide democratic parties, people’s organizations and people from all walks of life to conduct in-depth investigations and studies on major issues related to the implementation, revision and interpretation of the Constitution, and actively make suggestions and suggestions. It is necessary to expand the channels for citizens to participate in constitutional supervision in an orderly manner, explore the establishment of an opinion processing and feedback mechanism, and fully mobilize the enthusiasm of all sectors of society to participate in constitutional supervision, so as to have a broader consensus and a solid foundation.

  Fourth, the foundation of the constitution lies in inner support, and the power of the constitution comes from sincere belief.

  Only when the constitution is deeply rooted in the hearts of the people and enters the masses of the people can it truly become the conscious action of all the people. It is necessary to enhance the conscious awareness of the whole society to be loyal to, abide by, safeguard and apply the Constitution, establish the belief and awe in the Constitution, and provide spiritual motivation and ideological guarantee for comprehensively promoting the rule of law and building a socialist country ruled by law.

  Constitutional education is widely carried out in the whole society. The constitution is "a piece of paper with people’s rights written on it", which should be mastered, observed and used by the people. The "Decision" clearly designated December 4th, when the current Constitution of China was promulgated and put into effect, as the "National Constitution Day" every year, which provided an important opportunity for the centralized publicity and popularization of the Constitution. It is necessary to further improve the legal education system, highlight and strengthen constitutional education, make full use of various media to popularize constitutional knowledge, explain the spirit of the constitution, spread constitutional ideas, form a strong atmosphere for studying the constitution, and make the constitution a household name. It is necessary to bring constitutional education into the whole process of national education, starting with dolls and cultivating constitutional awareness from an early age. Through constitutional education, all the people should realize that the constitution is not only the highest code of conduct that must be observed, but also the most powerful weapon to protect their rights, fully believe in the constitution, actively use it, and become loyal advocates, conscious followers and firm defenders of the constitution.

  Party member cadres should take the lead in safeguarding the dignity of the Constitution. Party member cadres and state functionaries have an important leading and exemplary role in observing and maintaining the Constitution. The "Decision" requires that party organizations of people’s congresses, governments, CPPCC, judicial organs and procuratorial organs at all levels should lead and supervise their units to abide by the constitutional laws. It is necessary to establish and improve the system for party and government leading cadres at all levels to study the Constitution, regard the Constitution as the study content of the theoretical study center group of the Party committee (party group), as an important aspect of cadre education in party member, and list it as a compulsory course for Party schools and administrative colleges, so as to comprehensively strengthen the study and mastery of the contents and basic spirit of the Constitution. It is necessary to educate party member cadres, especially leading cadres, to take the lead in establishing constitutional consciousness, cultivate constitutional thinking, and take the constitution as the criterion for judging right and wrong; Take the lead in acting in strict accordance with the Constitution and enhance the ability to observe, analyze and solve practical problems according to the Constitution; Take the lead in promoting constitutional practice, conscientiously perform the duties entrusted by the Constitution, and fight against all acts that undermine the authority and trample on the dignity of the Constitution, so that the Constitution truly becomes the highest rule of state governance and the fundamental principle that must be followed in carrying out its work.

  Establish a constitutional oath system. The "Decision" clearly stated that "a constitutional oath system shall be established, and all state functionaries elected or appointed by the National People’s Congress and its Standing Committee shall publicly take an oath to the Constitution when they officially take office". The oath ceremony of the constitution strengthens the spirit of the constitution through solemn forms, which helps to enhance the sense of awe of the constitution and remember the solemn commitment made to the constitution; It is helpful to improve constitutional consciousness and cultivate constitutional belief. This innovative measure is of great significance for carrying forward the spirit of the Constitution and showing its authority. At present, among the 142 countries with written constitutions in the world, 97 countries have stipulated the oath system, and China is constantly exploring and practicing it. In March 2013, General Secretary of the Supreme Leader said at a meeting of the 12th National People’s Congress: "We will faithfully perform our duties entrusted by the Constitution, be loyal to the motherland, be loyal to the people, fulfill our duties, stay up all night in public, serve the people and do our best for the country." In December of the same year, 501 judges in the Supreme People’s Court solemnly swore allegiance to the Constitution and laws facing the national flag in accordance with the Provisions on Judge People’s Republic of China (PRC)’s Oath (Trial). We should conscientiously implement the constitutional oath system, clarify the specific procedures, contents, supervision and legal responsibilities of the oath, and make it a new important institutional form to ensure the implementation of the constitution and safeguard its authority and dignity.



  People’s Daily (November 11th, 2014, 06 edition)

Guangzhou has built the first expressway mileage in the province, and the main skeleton road network of "Three Rings+Nineteen Shoots" has basically taken shape.

Guangzhou has built a high-speed highway, ranking first in the province. The "three-ring+nineteen-shot" main skeleton road network basically formed the northern section of the second airport expressway. On December 30, the northern section of the second airport expressway invested and constructed by Guangzhou Jiaotou Group passed the handover acceptance and was open to traffic. After this section is opened to traffic, a second high-speed passage will be added directly to Baiyun Airport, so that citizens in the north and east of Guangzhou will not need to detour by plane. The North Section of the Second Airport Expressway connects the North Second Ring Expressway, Huaguan Expressway and other national highways such as G106 and S118, forming a closed-loop regional traffic pattern of Guangzhou Airport and a new northbound exit passage, which will further enhance the distribution capacity of Baiyun Airport and accelerate the development of the airport economic zone, and play an important role in improving the layout of Guangzhou expressway network, alleviating the "bottleneck" of northbound exit traffic in Guangzhou, constructing the Pan-Pearl River Delta expressway pattern centered on Guangzhou, and promoting the interconnection of Guangdong-Hong Kong-Macao Greater Bay Area. Up to now, Guangzhou has built a high-speed highway with a mileage of over 1,100 kilometers, ranking first in the province in terms of construction scale, and the "three-ring+nineteen-shot" main skeleton road network has basically taken shape. Avoid congestion and bypass to build a second high-speed passage through the airport. "Driving to Baiyun Airport, the airport expressway is the only way." Mr. Li told reporters. However, on holidays, the traffic volume increases, and the airport expressway is often congested. "Leave some time in advance for holidays in case the traffic jam can’t catch up with the plane." With the opening of the northern section of the airport’s second expressway, Mr. Li’s worries will be effectively alleviated.The second expressway of the airport starts from Shanqian Interchange on the north extension line of the airport expressway and ends at Huangcun Interchange on Guangzhou-Shenzhen Expressway, with a total length of 44.46 kilometers. The project is roughly bounded by the North Second Ring Expressway and is divided into the northern section and the southern section. The northern section of the project is 22.11 kilometers (including 1.36 kilometers of connecting lines), with the construction standard of 8 lanes in two directions and the design speed of 100 kilometers per hour, with 7 interchanges and 1 management center. After the opening of the North Section of the Second Airport Expressway, the high-speed network around Baiyun Airport forms a closed loop, and citizens have one more route to choose from to go to the T1 and T2 terminals of Baiyun Airport or the surrounding area. They can drive from the North Section of the Second Airport Expressway to Fanghua Road and then to the T1 terminal via T3 interchange. In the future, after the planned road at the airport is completed and opened to traffic, the accessibility of the road network will be further improved. Citizens can switch from the airport north interchange to the T2 terminal and from the T3 interchange to the T3 (planned) terminal, which will effectively alleviate the traffic congestion of citizens during holidays, and citizens in Huadu District and Baiyun District can also reduce road detours when going to the airport. It is reported that the south section of the second expressway of the airport has started construction in an all-round way. When it is completed and opened to traffic, it will connect the northern section of the project and China Unicom’s seven expressways, and become an important highway hub in Guangdong-Hong Kong-Macao Greater Bay Area, further improving the "three-ring+nineteen-shot" expressway network, focusing on upgrading the energy level of the external expressway corridors in the directions of Guanghui, Guang ‘ao, Guangzhao and Guangqing, helping to build a Pan-Pearl River Delta expressway network with Guangzhou as the center and create a "one-hour traffic circle" in Guangdong-Hong Kong-Macao Greater Bay Area."After the second expressway of the airport is opened to traffic, the driving time from Tianhe to Baiyun Airport will be shortened from 1 hour to 30 minutes, and it will also become the fastest way for major cities in Guangdong-Hong Kong-Macao Greater Bay Area such as Dongguan, Foshan and Zhaoqing to go to Baiyun Airport." The person in charge of the second expressway project at the airport said. Insist on green and intensive construction to build Guangzhou Expressway demonstration project. The northern section of the second expressway of the airport passes through urban dense areas, crossing (passing through) high expressways, national and provincial highways and rapidly transforming roads, railways and subways for many times. The buildings (structures) and pipelines along the line are complicated and the construction requirements are extremely high. In this regard, Guangzhou Jiaotou Group has always adhered to the new development concept, focusing on intensive land conservation, safe construction and green construction. In the overall scheme selection, the route should be optimized on the principle of occupying cultivated land, fertile land and economic forest as little as possible; In the design stage, bridge structure should be adopted as much as possible to reduce the land occupation; Minimize temporary land occupation during the construction stage; After completion, vegetation, cultivated land and municipal roads will be restored in time. In addition, rainwater collection and accident emergency pools are set up on the road section passing through the water source protection area, and rainwater and sewage on the road surface are collected and treated centrally; Sound insulation and noise reduction measures are adopted in the road sections passing through environmentally sensitive points such as villages, campuses and residential areas, such as SMA, OGFC and PAC combined noise reduction pavement and fully enclosed sound insulation screen, so as to minimize the impact on the surrounding environment. It is understood that there are two underpass tunnels in the northern section of the second expressway of the airport.They are the airport north tunnel, the longest two-way eight-lane expressway in China with a length of 3,012m, and the airport south tunnel, the widest expressway in China with a length of 1,100m. By adopting the scheme of underpass tunnel, the environmental friendliness is improved and the construction difficulty is also increased. "Airport North Tunnel is located next to Liuxi River, with complex geological environment and great risk of collapse." The person in charge of the project said. In order to overcome the construction difficulties, geological conditions are taken as an important consideration in the scheme design of the north section of the second expressway of the airport, and the scheme is dynamically adjusted during the construction, and measures such as real-time monitoring and strengthening protection are taken to ensure the construction safety. At the same time, the northern section of the second expressway of the airport makes the best use of the existing corridor resources in route selection, creates a three-dimensional traffic system and releases the urban development space. "For example, in the section of National Highway 106, there is a subway under it, with National Highway 106 in the middle and the second expressway above the airport." The project leader introduced. The project also innovated the way of pipeline relocation. For the first time in Guangzhou expressway construction industry, the comprehensive pipeline relocation unit was selected by public bidding, and multiple pipeline relocation routes were optimized by design and construction general contracting, and all pipeline property rights units were organized to participate in the design scheme discussion, breaking the "fragmented" situation of pipeline relocation, which not only greatly reduced the amount of land occupation and house demolition, saved investment costs, but also provided orderly pipe network layout support for future road network improvement.Promote innovation and empower BIM technology to lead smart construction sites to build the second high-speed airport project. BIM technology is also widely used in site construction and management, effectively solving construction problems in complex environments. According to reports, BIM technology is based on three-dimensional digital technology, which combines the BIM model established in the early stage with the surrounding real terrain, environment and other data through multi-channel image fusion technology to generate a real digital virtual sand table of the project, and escorts the project construction by intelligent means. How to move the pipeline? The model predicts first. The airport second expressway project innovatively uses "GIS+BIM" technology to establish a virtual digital sand table, and generates a visual three-dimensional model of the invisible underground pipeline. "Through the BIM model, the pipeline relocation can be arranged in advance. For example, seeing the close relationship between the pipeline and the subway and finding the conflict point of the pipeline relocation will make the actual operation more organized." The project leader said. The northern section of the project involves the construction of G106 bridge pier, capping beam and steel box beam, as well as the prefabrication and erection of beam and slab. The project adopts BIM technology to build an all-round three-dimensional real-life model communication platform, observe the site construction in 360 degrees in real time, strengthen the deep interaction between the project company and the construction unit, realize the scientific, standardized and intelligent management of the project based on BIM technology, and speed up the progress of the project. With this technology, the SG08 contract section of the North Section of the Second Airport Expressway completed an output value of 80 million yuan in a single month, setting a new record for the monthly output value of the bridge standard. It is understood that,The research results of the project on BIM technology also won many honors, such as the third place in the BIM application category of bridges and tunnels in the 10th imagine cup Building Information Model (BIM) Application Competition. Expand the skill competition mode, and the provincial key project labor competition will boost the project construction. During the construction process, the northern section of the second expressway of the airport will also vigorously carry out the provincial key project labor competition to adapt to the development of the new era. By expanding the depth of labor competition and innovating the skill competition mode, the construction upsurge of catching up with learning will be set off in the whole project, which will effectively promote the high-quality and efficient construction of the project. It is understood that since 2017, the project has carried out a series of labor competition activities such as "attacking the city and pulling out the village", "taking root", "flowering results" and "making new achievements", with the goal of "model project, clean project and quality project". Through a series of skill competitions, such as steel bar welding and upsetting straight thread sleeve connection, experimental testing practice, engineering survey practice, New Jersey guardrail steel bar binding and pouring, and the appraisal of craftsmen’s construction teams, post experts (pacesetters), advanced collectives and individuals, technical exchanges and mutual promotion have been realized, and the simple production and physical labor competition has been upgraded into an intelligent and scientific research competition, and four advanced collectives and three winners of Guangdong May 1 Labor Medal have emerged.

Blade of Hesitation: Focus on where the justice knife of juvenile delinquency points.

Special feature of 1905 film network The teenage girl was killed, but the real murderer was actually three minors?

They are demons who are numb to evil, cruel thugs, and "snakes and rats" who refuse to resist and fall. In the face of three unrepentant underage murderers, will the girl’s father punish the real murderer by law or in his own way?



The suspense crime film adapted from the novel of the same name was officially released on May 17th. This film focuses on the topic of "juvenile delinquency" and discusses where the sharp edge of justice should point in the hesitation between love and law.



In the movie: the emotional ups and downs caused by three kinds of hesitation



As early as during the screening of the film, many viewers expressed their feelings of "worrying and really hesitating" after the screening. Wandering from the title of the film to the film itself runs through.



The first hesitation comes from the father of the victim girl. After his daughter was subjected to inhuman abuse by a minor murderer, he fell into the trap of "am I a hand-edged murderer, revenging my daughter, or taking legal channels and waiting for the day when the law punishes them?" The entanglement.



For Li Changfeng, the father of the victim girl, "the law will punish them, but it will also give them a chance, but my daughter has no chance anymore."



The second hesitation lies in the spectator’s perspective. As He Jia, on the one hand, her simple sense of justice supports her to help Li Changfeng punish the murderer. At the same time, she is also urging Li Changfeng to turn himself in, firmly believing that the police and the law will bring these murderers to justice.



The third hesitation in the film comes from Liang Jun, a policeman. In the movie, he once let Li Changfeng go after controlling him, but when Li Changfeng was really ready to kill Xie Yu, the "head of the devil", he came forward in time to stop him. Liang Jun’s hesitation lies in, on the one hand, discouraging Li Changfeng and convincing him that legal means can sanction the murderer, but when Li Changfeng himself commits a crime, he should also be arrested.


Outside the film: social thinking inspired by four key turning points

There was a stepped sign at the premiere of the film, with four key words written from top to bottom: "joke, bullying, addiction and forgetting", which just correspond to the four key turning points of the film story.



The first is "joking". Xie Yu, the first of the three juvenile offenders, said in the film, "You don’t have the courage to play, do you?" . Wang Tianxiao, the accomplice, said, "It’s okay before you reach the age of 18. If it’s a big deal, just let your dad pay more." Luo Zhicheng also said, "I didn’t know that girl would really die."



These words are full of self-righteous jokes and ignorance of the law. Because for them, they are under the age of 18 and think that they will not be punished by law, so they naturally think that this behavior is just a game and a "joke". It is in the case that the joke is getting bigger and bigger that "bullying" begins to emerge, which is what we often say — — Bullying.


The third key word is "addiction". Just as Li Changfeng indulged in the grief of losing his daughter, he cried to the police, "I only have my daughter. My daughter is dead, so I can only sit here and wait quietly, waiting for the police to tell me how my daughter died and waiting for a fair referee to do justice for my daughter." In fact, there is only one obsession in his heart, that is, to speak out for his daughter. This deep love also made him finally go to the road of revenge on the murderer.



The fourth keyword "forgetting" can be introduced from a detail in the film. Before leaving home to seek revenge, Li Changfeng clung to his daughter’s favorite doll until the end of the film. Explain that Li Changfeng doesn’t want to forget his daughter, but the criminal suspects, these underage murderers who take pleasure in bullying, have they forgotten their previous criminal acts? Liang Jun, a policeman, said, "These children are not the most terrible, the most terrible thing is forgetting".



Xie Yu, the "head of the devil", had committed two crimes before committing this crime. On the first two occasions, he insulted the victim, but this time he killed Li Qian directly after insulting him. It is in this process of constant connivance and forgetting that his criminal methods are escalating step by step, and he has gone to a more serious criminal path. Therefore, the last keyword "forgetting" is two-sided. It is precisely because the murderer forgot the pain caused by the crime that he became insensitive and committed greater guilt. However, the families of the victims who have been hurt by forgetting will never get rid of this whirlpool of pain.


Law and film are working hard.


Laws and movies have also made a lot of efforts not to "forget" these vivid realities and lives. In the past, the law did not pursue criminal responsibility for crimes committed by minors under the age of 14, but in recent years, the mental development of minors has become more and more precocious, and the means of carrying out behaviors that endanger society have become more cruel. The law responded to these acts.



The 11th Amendment to the Criminal Law of People’s Republic of China (PRC) stipulates in Article 17 that minors who have reached the age of 12 but have not reached the age of 14 can be investigated for criminal responsibility if they commit intentional homicide, intentional injury and cause death, or cause disability by particularly cruel means. If the circumstances are bad, they can be investigated for criminal responsibility with the approval of the Supreme People’s Procuratorate.


Some time ago, in the case of juvenile delinquency in Handan, Hebei, these minors were over 12 and under 14. With the approval of the Supreme People’s Procuratorate, these three minors also entered the criminal proceedings, so what awaits them will be the investigation of criminal responsibility. Therefore, the law has chosen the strict side for minors in this respect, that is, not to "forget".



As a carrier of communication, movies sometimes play the role of spotlight and magnifying glass. At the beginning of this year, the film focused on the application of Article 20 of the Criminal Law of People’s Republic of China (PRC). Similarly, the film "Blade of Wandering" will also arouse people’s reflection and realize the blade of justice through legal means.


Academic scholar Li Weiwen: the whole story of the reconstruction plan of Beijing ancestral temple in Jiajing Dynasty of Ming Dynasty

Academic Scholar Li Weiwen: The Original Journal of Li Weiwen’s Architectural History from the Beginning to the End of the Reconstruction Plan of Beijing Ancestral Temple in Jiajing Dynasty of Ming Dynasty

In the tenth year of Jiajing (1531), Emperor Shizong of the Ming Dynasty initiated a reform of the ancestral temple system in Beijing, aiming at transforming the pattern of different rooms in the same room into the pattern of different halls in the capital. As an engineering decision-maker, Ming Shizong personally formulated the planning principles, and his assistant team submitted several rounds of design schemes and accepted the examination and approval of the emperor, which finally deepened the design scheme and practice of Nine Temples, which was recorded in history. This process was recorded in detail by Xia Yan, a courtier, which not only helps to deepen the understanding of the evolution of the ancestral temple in Beijing, but also helps to understand the operation mode of ancient architectural projects in China and the role of architects.

The whole process of reconstruction planning scheme generation

Li weiwen

After Zhu Houzong (hereinafter referred to as Emperor Shizong of Ming Dynasty) ascended the pole, a series of national sacrificial rites reforms were launched, and the altar and temple facilities in Beijing were completely transformed. After Zuo Shunmen’s incident, the results of the big ceremony for his biological father (Xing Xian Di) God gradually stabilized, but Ming Shizong was always unwilling that the ancestral temple (Figure 1) failed to make a better temple system. The reform of the temple system in the later stage of Shizong in Ming Dynasty can be regarded as the continuation of the great ceremony in depth.

Figure 1 The plane state of Beijing ancestral temple in 1942.

The controversy over the ritual system is not the only obstacle for Ming Shizong to practice his personal temple system. On the specific renovation planning of the ancestral temple complex, Ming Shizong also felt a considerable obstacle, that is, as he said, "it is difficult to make the temple system more correct." In order to change the temple system, Ming Shizong launched a far-reaching action. The final result of this action was the completion of the Jiumiao complex at the end of the 15th year of Jiajing (1536) and the implementation of the new memorial ceremony. Until the 20th year of Jiajing (1541), the pattern of Jiumiao was destroyed by fire, which constituted a short and compact chapter in the history of Beijing ancestral temple (Figure 2). Yan Kai has basically combed this process in his thesis "Research on the Architecture of Beijing Ancestral Temple". However, the transformation of the ancestral temple from the original regulation of different rooms in the same room to the pattern of different halls in the same palace did not happen overnight, but it went through repeated planning and many scheme adjustments for quite a period of time. The gradual deepening of this series of architectural schemes was recorded in detail in the script of the participants such as Xia Yan, the assistant minister. Through these historical records, this paper attempts to restore the formation process of the planning and design scheme of the nine temples in Jiajing, Ming Dynasty, and to get a glimpse of the decision-making operation in the planning and design of national architecture in Ming Dynasty.

Determination of planning conditions and Zhao Shanming’s scheme

As early as a few years before Emperor Shizong of the Ming Dynasty really started to promote the reconstruction of the ancestral temple, he had revealed his plan to transform the ancestral temple into a palace hall on many occasions. One of the earliest times was a duet recorded by Li Shi in his "South City Calling Couples". Li Shi didn’t record the specific time of the dialogue, but according to Xia Yan’s record of the same performance in his book "Taking into account the ancient and modern temple system, begging for clarity and breaking the sparse", it can be known that it happened in November of Jiajing Decade (1531). In this dialogue, Emperor Shizong of Ming Dynasty raised the concern that "the ceremony of worshipping a hundred gods in the suburbs is correct, but the ceremony of the ancestral temple is not perfect", and cited the story of Ming Taizu’s establishment of the four-parent temple, advocating the transformation of the ancestral temple into the form of a palace. However, the attitude of several ministers is very cautious. On behalf of several ministers, Li Shi first expressed the attitude that "the ceremony of nine temples is impossible". This attitude is not only considered from the perspective of etiquette, but also involves the time and physical strength required for the emperor to worship the nine temples. However, Emperor Shizong of Ming Dynasty did not elaborate or defend the connotation of the ritual system of the Nine Temples, but directly made a statement on his idea of transforming the ancestral temple: "I want to stay in the main hall. It is said: it is good not to move the hall. When I was a minister, I said, Don’t you move the bedroom? Above, they said, "None of the three halls will move.".

Emperor Shizong of the Ming Dynasty explained the basic planning conditions for the reconstruction of the ancestral temple to his closest officials, which actually explained the overall scale of the project and the disturbance degree to the main building of the existing ancestral temple. By determining the first principle that the three halls of the ancestral temple should not be demolished and rebuilt, Emperor Shizong of Ming Dynasty hoped to dispel his officials’ doubts about the nature of the project and gain their support. In the dialogue, Emperor Shizong of Ming Dynasty denied Xia Yan’s solution of temporary structures, and determined the permanent architectural nature of the project. By promising the planning principle of "don’t have to fit the ancient" and "don’t move the main hall, only use two temples ….. only have its meaning", the upper limit of the total project is explained, which dispels the exaggerated imagination and worry of the liegeman about the concept of "all palaces and separate halls". As a result, Xia Yan and others’ attitudes were obviously eased. "At first, I saw the sacred worry … the three halls did not move, and things were easy." A design team began to form.

Nevertheless, the Dugong Biedian is still a vague concept of etiquette, leaving a lot of room for specific architectural forms. The so-called Nine Temples can be nine groups of buildings with similar scale (such as the Nine Temples of Wangmang) or a complex with clear priorities, and the ritual connotations of these possibilities are different. After this performance, Xia Yan put forward two obstacles for the ministers to make the plan of the Nine Temples. First, the ancient ceremony required Zhao Muqun Temple to be in the south of the ancestral temple, but the land south of the ancestral temple was not plentiful: "If the temple of three Zhao and three Mu was in front of the ancestral temple according to the ancient system, it would be very far from the south of the imperial palace to the Chengtianmen wall. Even if you do your best to build a group of temples, you will be afraid of the situation. " Secondly, the scale of Zhaomu temples in ancient rituals is imitated as ancestral temples or only slightly increased or decreased. If such a design is adopted, the shortage of land will be aggravated. However, if the scale is reduced to the extent that the existing land can be accommodated, it is not appropriate in the ritual system: "The ancients had seven temples and nine temples, and the system was the same. The structure of the ancestral temple is extremely grand and strong, and the temples in the group are humble, so I am afraid it is not called the residence of the nine temples before my death. " The solution of these two contradictions runs through the whole project planning.

In the 11th year of Jiajing (1532), Zhao Shanming, an experienced officer of the Chinese army, introduced the reconstruction scheme of the ancestral temple (numbered scheme I in this article), and Emperor Shizong of the Ming Dynasty ordered the auxiliary ministers to evaluate the scheme. On March 12th of that year, Xia Yan refuted Zhao Shanming’s visit to the temple in his book Refuting the Experience of Zhao Shanming’s Temple, directly questioning Zhao Shanming’s "lack of etiquette". Surveying and mapping the ancestral temple without permission, "measuring refers to painting" and "things are good at drawing". However, since Emperor Shizong of Ming Dynasty ordered Xia Yan and others to evaluate Zhao Shanming’s proposal, it shows that he is interested in the proposal and at least agrees with some of its ideas. Therefore, Zhao Shanming’s plan can be regarded as the first conceptual plan for the transformation of the ancestral temple.

Zhao Shanming first emphasized in his recitation that his plan followed the planning principle defined by Emperor Shizong of Ming Dynasty, and that "the ancestral temple, the second bedroom temple and the Golden Gate were all untouched". The main points of its plan are as follows:

Expand the whole land of the ancestral temple and push out the existing ancestral temple wall to the four sides. The east wall of the expanded ancestral temple is close to the west wall of the World Temple, leaving five feet between them, and the existing river channel between the ancestral temple and the World Temple is changed into a culvert; The north wall is in line with the north wall of the World Temple; The western wall reaches the corridor along the front line of the end gate and the noon gate, leaving five feet behind; The south wall reaches the imperial city wall on the east side of Chengtianmen, leaving five feet with it. The five-foot gap left in the above three directions will form a "U"-shaped carriageway. The expanded land for the ancestral temple completely occupies the area east of Liuke Gallery, south of Tongzi River and west of the World Temple, which will basically occupy the existing pine and Berlin.

Due to the external expansion of the walls of the ancestral temple, the main courtyard of the ancestral temple will be independent from the center of the land. Taizong Temple and Sanzhao Temple are arranged on its east side, and Sanmu Temple is arranged on its west side, with a total of seven groups of buildings. Zhao Shanming demarcated each group of construction land as 30 feet deep and 28 feet wide, and reserved tunnels in between. According to its own calculation, except for Taizong Temple, Sanzhao and Sanmu are arranged from the new south wall of Taizong Temple to the north, with a total depth of 95.4 zhangs, and its land use is the same as the southern edge of the pedestal of Taizong Temple. The World Temple maintains the status quo (Figure 3).

Fig. 3 The idealization of Scheme I refuted in Xia Yan’s recitation on March 12th, 11th year of Jiajing (1532) in Gui Zhou Recital.

Left: there are both ancestral temples; Right: Planning the ancestral temple

It should be noted that Zhao Shanming’s reconnaissance and design work are all his personal behaviors, and his grasp of the overall scale of the ancestral temple is quite biased. If, according to the real scale of the ancestral temple area, the wall branch is expanded as planned, the central building complex of the ancestral temple will not be in the middle of the area, but will be slightly west. It is also difficult to realize the scale of the group temples designed by Zhao Shanming. Once arranged, it will completely fill the space on both sides of the ancestral temple, especially on the narrow west side. If a group of temples are arranged with a width of 28 feet, it will not meet the 5-foot-wide imperial road in the temple street gate reserved in Zhao Shanming’s plan. Therefore, the performance in Figure 3 of this paper has made some adjustments to the scale of the group temples, and the size of the group temples in the figure is slightly smaller than the data given by Zhao Shanming to reflect the original intention of the scheme.

In addition, Zhao Shanming’s plan also involves a number of environmental adjustments, including using the existing rocks in the pine forest of Taimiao, "after moving to the World Temple, fill the river and fill it up, and grow more pines and cypresses to protect the Xuanwu side"; Plant more flowers and trees in front of the ancestral temple. With regard to the material raising for the project implementation, the scheme even puts forward the idea of designing the large wooden structure in advance and sending it to the southern provinces to deliver the large wooden components to Beijing after production, which is quite imaginative. However, all these proposals were refuted by Xia Yan. Xia Yan only affirmed Zhao Shanming’s proposal that Taizong and Shimin temples should not enter Zhaomu and remain immortal out of his observation of the original intention of Ming Shizong’s ritual painting.

Looking at Zhao Shanming’s plan, its overall idea basically meets the planning conditions proposed by Ming Shizong, but its planned area for Zhaomu Temple is too large, and the existing trees are cut down too much, which does not reflect the original intention of Ming Shizong to accommodate new buildings only in two spaces. In addition, its scheme only affirmed the immovable status of the World Temple from the ritual system, but did not give an architectural solution, which could not satisfy the selfishness that Ming Shizong did not point out, which was an important weakness of the scheme.

The deepening of Zhao Shanming’s plan and the plan of Jiumiao Dugong

After Xia Yan’s criticism, Zhao Shanming’s plan was also rejected by Ming Shizong. But soon, on the second day of April in the 11th year of Jiajing (1532), Xia Yan went to the book "Rules and Regulations on Building a Ancestral Temple in Jincheng" and introduced two improvement schemes with several courtiers and internal supervisors, which showed that Zhao Shanming’s proposal really extended the discussion on the temple system for some time.

Xia Yan mentioned in this lecture that after the personnel who participated in the engineering design made a reconnaissance of the ancestral temple, a plan for expanding the outer wall of the ancestral temple in three directions (scheme II in this paper) was briefly put forward. In fact, this plan is very close to the idea of Zhao Shanming’s plan, that is, expanding the land for the ancestral temple to accommodate the group of temples, but the scale of this expansion is far smaller than that of Zhao Shanming’s plan, and it is still basically controlled outside the two temples of the existing ancestral temple (Figure 4). The biggest adjustment of Zhao Shanming’s scheme in Scheme II is to give up the idea of trying to strictly control the land of Zhaomu Temple in the south of the existing ancestral temple according to ancient rites, thus greatly alleviating the land shortage on the south side of the ancestral temple in Zhao Shanming’s scheme. The scale and arrangement of the group temples were not mentioned in the recital, but we can see that the total depth of each group temple in the east and west still exceeds the existing ancestral temple land, and the purpose of expanding the south wall is to form a new capital palace to match the total depth of the group temples. However, it is not stated in the recitation whether the Taizong Temple, the ancestral hall of Wenzu, is also included in the scope of the capital palace.

Fig. 4 Scheme II mentioned in Xia Yan’s recitation on the second day of April in the 11th year of Jiajing (1532) in Gui Zhou Memorial.

Left: Existing land; Right: Planned land use

It is recorded in the notes that this design has undergone a new adjustment, forming another scheme (scheme ⅲ in this paper), that is, the east-west wall remains completely intact, and only the width of two gaps is used to accommodate the Zhaomu Temple; The south wall is still spreading to the south, but to a lesser extent: "There is no need to spread the east and west walls, but only 14 feet and 4 feet in the wall divided by 20 feet and 9 feet as the royal road, 11 feet and 5 feet as the width of the temple, and 22 feet and 5 feet as the depth of the temple … The temple gate wall only spreads to the south by 80 feet and 8 feet".

In this scheme, each group of Zhaomu temples is arranged vertically, and two royal roads connecting the temples run through from the inside, forming a ∩-shaped passage with the tunnel between the back wall and the back wall of the temple. According to the design of 8.8-foot south extension of the south wall of Taimiao in this plan, Taizong Temple has been clearly incorporated into Dugong at this time: expanding the south wall by 8.8-foot on the basis of the total depth of 81.2-foot of Taimiao will form a Dugong with a depth of 90-foot, and the hatchback can just accommodate four temples adjacent to the north and south with a depth of 22.5-foot (Figure 5). The planning of Jiumiao Dugong was thus formed.

Fig. 5 Scheme III mentioned in Xia Yan’s recitation on the second day of April in the 11th year of Jiajing (1532) in Gui Zhou Memorial.

Left: Existing land; Right: Planned land use

This plan has not involved the architectural design of each temple in detail, but only mentioned that "each temple will only build a main hall with five rooms" and there is no sleeping hall. It shows that the officials who participated in the design at this time have fully understood the instruction of Ming Shizong about the design of group temples, and no longer pursue the perfection of regulation and the far-reaching scale. At this point, the feasible factors in Zhao Shanming’s scheme have been basically extracted, while his exaggerated assumption on the scale of land use has been abandoned. However, for this deepening plan, Emperor Shizong of the Ming Dynasty only approved "Stop", and the reconstruction of the ancestral temple was put on hold for some time. Perhaps this is still due to the controversy over the connotation of the ritual system.

On September 8th, 13th year of Jiajing (1534), Xia Yan and others were ordered to visit the ancestral temple again, and a new round of design began. The origin of this design was the disaster of the ancestral temple in Nanjing, which was interpreted by Xia Yan and others as the auspicious feeling that ancestors expected the new temple system, which made Ming Shizong make up his mind. Xia Yan quoted the architectural design scheme of a group of temples personally put forward by Emperor Shizong of Ming Dynasty in his Regulation of Seven Temples at the Order, that is, "the system does not need to go far from the front and back temples, that is, the front hall has five rooms, the tiger seat is backward, and three rooms are connected to the dormitory from Zhangyu, which is also righteous." The reason why Emperor Shizong of the Ming Dynasty took the lead in guiding the design of the buildings of the ancestral temples when the overall pattern of the renovation was not yet determined was that on the one hand, he insisted that the regulations of the temples still needed to be complete, denying the simple design of each temple with only one main hall, on the other hand, he restricted the occupation scale of the newly-built temples, further reducing the impact on the existing pattern of the ancestral temples.

Fig. 6 Scheme IV mentioned in Xia Yan’s recitation on the eighth day of September in the 13th year of Jiajing (1534) in Gui Zhou Memorial.

Left: Existing land; Right: Planned land use

According to Xia Yan’s recitation, "It was originally planned that the regulations of the temples would reach the south wall of the ancestral temple, then the east and west temple walls would go out before the Jimen Gate of the ancestral temple, and there would be obstacles in the kitchen of the Shenku". It can be seen that there was still an intermediate scheme (scheme IV in this article) between the eleventh year of Jiajing (1532) and this new discussion in the thirteenth year of Jiajing (1534). In this scheme with unknown formulation time, the south wall of Taimiao does not expand to the south, indicating that the total size of the temples has been reduced again. However, the land for Zhaomuqun Temple will still stand out from the south of Jimen Line, "reaching the south wall of Taimiao". The design of the extended hatchback, such as schemes III and IV, will lead to the narrowing of the square between the Jimen Gate and the Liulimen Gate of the Imperial Temple, and at the same time, it is necessary to move the Shenku Shenchu and Jingting (Figure 6). These problems may be the reason why Ming Shizong personally restricted the scale of the main buildings of various temples in September, 13th year of Jiajing (1534). Under the new guidance, the area occupied by the temples in the group can continue to shrink, and the southernmost part "merges with the side door of the ancestral temple gate, and the straight north back wall merges with the ancestral temple temple", and a new scheme of "solemn potential" (scheme V in this paper) can be formed. From then on, all the designs that caused the uneven parts of the land or the need to move the wall were put an end to.

Fig. 7 Plan V mentioned in Xia Yan’s recitation on the eighth day of September in the 13th year of Jiajing (1534) in Gui Zhou Memorial.

Left: Existing land; Right: Planned land use

The plane pattern logic of scheme V is completely the same as that of the later implementation. Compared with the above-mentioned schemes, the difference between them and schemes I, II and III is that the four external walls are not expanded; The difference with Scheme IV is that the inner wall does not move, while the new wall strictly follows the extension line of the existing frame. In the new scheme, the scale of each temple group is equal, the depth is 16.15 feet, and the total depth of the temples group is 64.6 feet. This value is completely consistent with the distance between the existing halberd gate and the back wall of the temple (that is, the total depth of the two gaps is 67.5 zhangs minus the width of the tunnel behind the temple of the temple of the temple of the temple of the temple of the temple of the temple of the temple of the temple of the temple of the temple of the temple of the temple of the temple of the temple of the temple of the temple of the temple of the temple of the temple of the temple of the temple of the temple of the temple of the temple of the temple of the temple of the temple of the temple of the temple of the temple of the temple of the temple of the temple of the temple of the temple of the temple of the temple of the temple of the temple of the temple of the temple of the temple Scheme V was finally approved by Emperor Shizong of Ming Dynasty, and the reconstruction project of Taimiao entered the preparatory stage of the project. It is expected to start in the spring of the 14th year of Jiajing (1535). At this point, all the intentions of the Ming Shizong to transform the ancestral temple into a palace hall have been implemented in the planning, but another important intention of the Ming Shizong to initiate the temple system reform, that is, the relocation of the temple, has not been reflected in the above design process.

Moving in and Design of the World Temple

According to the Regulation of the World Temple on the 8th day of February in the 14th year of Jiajing (1535) included in Gui Zhou Memorial, it seems that the idea of the moving in and specific regulation of the World Temple in Ming Shizong started a little late, more like a parallel project with the transformation of the Imperial Temple Palace. Some studies believe that in the design of the Imperial Palace of Taimiao, there are four groups of buildings, namely ShiShi Temple and Sanzhao Temple, on the left, while Sanmu Temple is on the right. The land opposite to ShiShi Temple may be the location reserved by Shizong in Ming Dynasty for Ruizong. But in fact, in the paintings of the ancestral temple of Shizong in the Ming Dynasty, the temple was always the capital palace for itself. At this stage, there was no attempt to merge the God of Ruizong into the capital palace of Taimiao. In terms of etiquette, even after the reign of Emperor Ruizong in the 17th year of Jiajing (1538), there was at most a dispute with the ranking of Wu Zong, and there was no reason to directly override the three Mu. From the architectural point of view, the existing temple at that time occupied a large area, and its main building was regulated according to the Wenhua Temple ("In the east of the brick city, within the imperial city, the south city is as far north as possible or a temple is set up in the east. The porch of the bedroom door behind the front hall is like the Wenhua Hall "), which is much larger than the planned Zhaomu Temple in the Imperial Palace and the planned Wenzu World Room. If we must move into the extremely cramped space of the Imperial Temple Palace, it will inevitably lead to a situation that the regulation of the new world temple is not as good as that of the existing one, which is absolutely unacceptable to Ming Shizong. Therefore, the hypothesis that the virtual master treats the Rui Sect is debatable.

The early planning of the New World Temple is not recorded in the literature. By the time Xia Yan published "Rules and Regulations on the Temple of the World" in the 14th year of Jiajing (1535), the design of the World Temple had actually begun. According to the imperial edict of Emperor Shizong of the Ming Dynasty, "The World Temple proposed by Qing et al. yesterday was regulated in the east of Taimiao, and trees could not be moved", indicating that the World Temple was originally located on the land adjacent to the east side of Taimiao Dugong. For the sake of cutting down trees as little as possible, Emperor Shizong of Ming Dynasty finally chose Xinshi Temple as "a wide place in the southeast of the ancestral temple … which stops at Shenshen Road in the north and reaches the east wall of Chengtianmen in the south, with a total length of 63 feet and 3 feet". However, the Xinshi Temple is not adjacent to the Great Wall of the Imperial City, but only occupies the northern part of the land: "The depth of the north and south … is 35 feet and 9 inches, and the width of the temple street in the south is 27 feet and 4 feet". In this way, the Xinshi Temple is actually embedded in the gap between the Imperial Palace and the east channel of the Imperial Temple, and its overall pattern is not plentiful (Figure 8). In the 22nd year of Jiajing (1543), the Imperial Palace was destroyed by fire. After a site survey, Yan Song made a more detailed description of the site selection pattern of the surviving Xinshi Temple (then known as Ruimiao Temple), saying that "another waist wall outside the east wall of Ruimiao Temple is near the deep ditch. This ditch is the way for the inner imperial city to pass water … It is found that the base of the old temple is more than 63 feet across, and now the ground is added to the ditch in the east wall, which stops at 19 feet. " It is conceivable that the New World Temple, which is only 19 feet wide, is arranged in this gap, and its width is 17 feet wide.

Fig. 8 The site selection data of the World Temple mentioned in Xia Yan’s recitation on the eighth day of February in the 14th year of Jiajing (1535).

Left: Existing land; Right: Planned land use

It is further pointed out in "Rules and Regulations on the Temple of the World" that the original design of the Temple of the World was "nine front halls, seven rear bedrooms … seven in front of them … seven in back … five in back … five in halberds … and its rules and regulations are almost the same as those of the ancestral temple. Considering the narrow scale of the land used for the New World Temple, this design may mean a particularly compact opening rhythm (this compact opening rhythm to ensure the number of rooms can be seen in the Jingdechong Temple, the imperial temple in Beijing, which was also created for the ritual system of Jiajing Dynasty). Why this design was finally abandoned has not been mentioned in the literature.

The regulation of the architecture of Xinshi Temple was finally determined as seven front halls, five rear bedrooms, five front two bedrooms, three rear two bedrooms and five halberds. The specific scale of each single building is attached with pictures, but unfortunately it has not been handed down from generation to generation. After that, Emperor Shizong of the Ming Dynasty said that "the height of the temple should be adjusted from now on, and the rest should be adjusted according to the plan", which seems to have been adjusted in detail. Only the follow-up information has not been published in the literature.

Strengthening the regulation of Taizong temple and the architectural design of each temple

Before the actual construction of Jiumiao Dugong, its design underwent another adjustment, the main purpose of which was to increase the temple regulation of Taizong Temple and make it different from Zhaomu Temple. In Reconsidering the Rules and Regulations of Seven Temples in the 13th year of Jiajing (1534), Xia Yan introduced a fine-tuning scheme, trying to heighten the Taizong Temple without changing the established graphic design of the scheme. Generally speaking, there are many ways to improve the design height of a temple, and the height can be found on the abutment, column height, paving layer and roof elevation. However, the lifting height of the large wooden structure is generally limited by the depth ratio of the temple, and it is impossible to increase it arbitrarily. In the graphic design scheme of Taizong Temple, which covers the same area as Zhaomu Temple, "because the base site is the same, it is difficult to worship Dongyu". In this fine-tuning scheme, the front hall and the sleeping hall of Taizong Temple are barely one foot, four inches, five minutes and five inches higher than those of the group temples. This symbolic increase is difficult to observe with the naked eye in the Jiumiao complex with high building density.

Fig. 9 Scheme VI mentioned in Xia Yan’s recitation on October 23rd, 13th year of Jiajing (1534) in Gui Zhou Memorial.

Left: Existing land; Right: Planned land use

Therefore, Emperor Shizong of the Ming Dynasty immediately requested that "the imperial ancestor Taizong’s family room should be added again". Therefore, Xia Yan and others decided to adjust the plane pattern of Jiumiao building complex again, expand the scale of Taizong Temple, reduce the depth of the temple group from 16.15 feet in the plan to 16 feet, and merge the vacated space into the land for Taizong Temple, so that the depth of Taizong Temple reached 16.6 feet, providing space for the worship of the temple. After the above adjustments, this version of the floor plan (numbered scheme ⅵ in this paper) was finally determined as the implementation scheme of Jiumiao Dugong (Figure 9).

After this adjustment, the temple regulation of Taizong Temple was finally able to distance itself from Zhaomu Temple. The increasing degree of the design data of the single hall of Taizong Temple mentioned in the recitation can also reverse the design scale of the group temple buildings, which is summarized in Table 1:

Through site adjustment, the height of the front hall of Taizong Temple is 0.445 m higher than that of Zhaomuqun Temple, and the height added on the abutment is 0.1 m, which shows that the height added on the wooden structure or tile is 0.345 m.. The height of the sleeping hall of the world room is 0.2 zhangs higher than that of the sleeping hall of Zhaomuqun Temple, and the height added on the abutment is 0.1 zhangs, which shows that the height added on the wooden structure or tile is also 0.1 zhangs.

With the actual progress of the reconstruction project, Xia Yan further detailed the dimensions of the Ming rooms in front of each temple in his "Sketch of the Regulation of Objects in Jincheng Ancestral Temple" on the third day of August in the 14th year of Jiajing (1534). These data are helpful to further restore the architectural design in the new temple system (Figure 10).

Fig. 10 Scale summary diagram of newly-built temples and courtyards in Gui Zhou Memorial and its pattern restoration hypothesis.

According to the architectural pattern design of the temples put forward by Ming Shizong in September of the 13th year of Jiajing (1534), "There are five front halls, with the tiger seats backward, and three bedrooms are connected after the zhangs". It is speculated that in the final implementation plan of the transformation of the ancestral temple, both the ancestral temple and the Zhaomuqun temple are only the front halls and the rear bedrooms, and there are no two guards and halberds. As for the tiger-seat eaves behind the front hall, it is a common practice in temples and ritual buildings in the Ming Dynasty, and it should be as wide as the Ming Dynasty, but its exact depth has not been recorded in the literature. In Figure 10, the images are expressed by dotted lines. The scale of the World Temple is longer than that of other newly-built temples to accommodate the Jimen and the two temples, and its overall pattern is similar to that of the main courtyard of the Imperial Temple. The width and height of the front and rear halls of the World Temple are not recorded in Gui Zhou Recital, but it can be seen from the Sketch of the Regulation of Objects in Jincheng Ancestral Temple that the scale and depth of the Ming Dynasty (the "depth of the Ming Dynasty" recorded in this sketch is actually the total depth of the building) are obviously larger than those of Taizong Temple and Zhaomu Temple.

With regard to the architectural design of the temples and bedrooms, except for the World Temple, given that the front halls of each group of temples are five rooms wide, according to the common practice of temples in the Ming Dynasty, if the other rooms have equal spans, the dimensions of other rooms of these buildings can be calculated from the Ming Dynasty. With reference to the architectural examples of the Ming Dynasty and the existing buildings of the ancestral temple, on the premise that the existing single building of the ancestral temple complex has a saving distance of no more than 11 doukou, assuming that the saving distance of the newly-built temples is 11 doukou, it can be further inferred that the materials used are as shown in Table 2:

The regulation of sleeping halls in newly-built temples is rarely recorded in the literature, and there is no data on the scale of Ming Dynasty. However, considering the design rules of the building complex, its materials should be the same as the corresponding front hall. At present, each single building on the central axis of the ancestral temple is 4 inches, and the newly built temples adopt smaller buckets, which is also consistent with the intention of "respecting the ancestors" in Jiumiao Dugong. The width and depth of each hall are all zero, especially ending with nine points and nine inches. In addition to the auspicious factors, it is likely to include the consideration of the side feet of eaves columns in order to obtain a more complete size in the paving layer and roof.

Fig. 11 Presumption on the standing of the front and back temples of Jiajing Taizong Temple (World Room)

The literature does not specify the height of each temple abutment and the roof shape, and this paper does not focus on restoring the single building shape of each temple. Generally speaking, judging from the ratio of the height to the depth, the front hall of Taizong Temple and the front halls of all temples should be double eaves, otherwise the roof height or abutment height will be too high. In the Ming Dynasty, the proportion of halls and halls was wide and flat, and in extreme cases, the height of eaves and columns could only reach about 60% of the width of rooms and halls. Assuming the front hall of the Temple of Etai, the eaves column is about 14.16 feet high, and the height of the golden column is about 26.9 feet if calculated by 1.9 times the eaves column. Assuming that the depth of the front hall of Taizong Temple is 4.009 feet, the depth of the secondary steps accounts for two distances before and after, and the upper eaves are paved with seven steps and a single elevation, the depth of the upper eaves is about 2.673 feet. According to the roof height of 3: 1 and the abutment height of 6 feet, a draft design of side vertical sample can be obtained (Figure 11). Considering the height of the ridge tiles of the temple, the height of the temple can basically be consistent with the ruler contained in the literature, and the proportion is reasonable.

On the national etiquette system from the perspective of the nine temples project

Decision-making and planning principles of buildings

The design process of Jiajing’s renovation of ancestral temple revealed some renovation principles of large-scale buildings such as national altar temple in Ming Dynasty. The graphic design of national large-scale buildings in Ming Dynasty followed a series of laws of scale and proportion, which was discussed in detail by Mr. Fu Xinian in the article "Characteristics of Master Planning Techniques of Beijing Palace Temple and other large-scale buildings in Ming Dynasty". On this basis, the Research on Architectural Design of Beijing Imperial Temple further points out that the two walls inside and outside the main body of the Imperial Temple, and the walls and individual building scales all cooperate with each other, such as the width of the outer wall is equal to the depth of the inner wall, and so on.

However, this carefully constructed plane pattern was once challenged unprecedentedly when Jiajing rebuilt Jiumiao Temple. A series of preliminary process schemes sorted out in the above article have interfered with the original pattern of the ancestral temple complex to varying degrees. The author speculates that in Jiajing period, the design data of Yongle Zhaozao ancestral temple and Hongzhi Zengjian temple may have been missing, and some precise intentions in the initial graphic design are no longer known. The opportunities for ministers and workers to actually contact the ancestral temple space are extremely limited, and it is even more difficult to understand the proportion and modulus contained in its plane pattern. Interestingly, the subsequent design deepening process of Jiumiao complex happened to be a process of gradually returning to Yongle-Hongzhi plane planning. In the early planning, the disturbance to the original plane was gradually reduced and neutralized, and finally, the principle of design under the original plane framework was completely established. As for the reasons behind this process, on the one hand, it is the guidance of the planning principle of "minimum intervention in plane" determined by Emperor Shizong of Ming Dynasty, on the other hand, it may also be that the officials and ministers gradually realized the intention of the original plane design of Yongle-Hongzhi in the round of deepening the plan. Judging from the fact that the gate wall of the Temple of God, which was built in the 24th year of Jiajing (1545), still follows this plane frame, the original design intention of the ancestral temple complex should have been clearly understood by the monarch and his ministers at that time.

With the help of the above planning and design, we can also get a glimpse of the decision-making process of the transformation of a group of buildings located at the top of the national etiquette system in Ming Dynasty. In this process, it is particularly noteworthy that the emperor’s auxiliary ministers participated in the planning. It is generally believed that the design process of large-scale official construction projects in the history of ancient architecture in China is significantly different from that in the West. In the west, architects with independent professional status often intervene in official or royal projects by participating in bidding and accepting entrustment. The deepening, promotion and adjustment of the design scheme form a complete cycle of creation, cooperation and game, which is closer to the mode of contract signing by Party A and Party B in contemporary construction projects. In ancient China, however, the role of national engineering architect was much more vague. On the one hand, it was undertaken by the emperor himself as the project decision maker, on the other hand, it was undertaken by the craftsmen and wood factories as structural engineers and builders, and there seemed to be a lack of a docking layer between them. However, by observing the design process of Jiumiao architectural complex in Jiajing period, it can be found that the auxiliary ministers around the emperor played an important role in the decision-making of specific engineering projects, although they did not necessarily have a civil knowledge background. On the one hand, they had the opportunity to listen to the emperor’s instructions on the project planning principles and put forward their opinions. On the other hand, their direct reconnaissance of the project site also formed the basis for further design work. Before the specific project is truly assembled, there may be many schemes put forward by them for discussion and deepening. These steps make up for the "design" gap between planning and construction; The construction engineering literacy of the auxiliary ministers constitutes the "group role" of the ancient architects in China.The important attribute of "X" is worthy of further analysis in future research.

Residual theory

Scholars such as Mr. Fu Xinian and Yan Kai have found that the graphic design of the ancestral temple in Beijing adopts a square grid of 50 feet as the basic module, and tried to restore the original design scale of the ancestral temple through modern surveying and mapping data. However, all kinds of scale data in the design process of the reconstruction of the ancestral temple mentioned in Xia Yan and others’ notes can undoubtedly push this exploration forward.

If we compare the scales in documents related to Jiajing’s transformation of ancestral temple with those restored by Fu Xinian and Yan Kai (Table 3), we will find that the scale data obtained from reconnaissance in historical documents do not completely correspond to the modulus of five feet, and are often not integer feet. On the one hand, it shows that there may be differences between ancient surveying and mapping accuracy and design accuracy, on the other hand, it also shows that plane modulus is not the only design principle of large-scale buildings. The engineering and cognitive factors behind this need to be further explored.

Most of the literature data are in good agreement with the measured reduction data, and the measured reduction scale is generally slightly larger than the literature scale. Considering that the modern surveying and mapping data and square modulus analysis adopted by Mr. Fu Xinian are based on the wall skin, these deviations may mean that the surveying and mapping data in the Ming Dynasty literature are based on the wall centerline. The difference of the above data is generally within the control range of the project, except for the item of the depth of the great wall of Taimiao complex from north to south, there is a significant difference of about 3.8 zhangs between the document scale and the actual scale, and this difference is caused by the difference of the depth of Jimen Square. This shows that at some point since the transformation of the ancestral temple in Jiajing period, the southern wall of the ancestral temple has indeed been expanded to the south. When did this expansion happen? Was it when the ancestral temple was rebuilt in the 22nd year of Jiajing (1543) or when the river bridge in front of Jimen Gate was expanded in the 28th year of Qing Qianlong (1763)? If the south wall of the existing ancestral temple is retracted 3.8 feet to the north, the geometric center of the formed large wall will fall on the front eaves of the enjoyment hall. Is this the original design intention when the ancestral temple was founded in Yongle period? These are still problems to be solved.

In the 24th year of Jiajing (1545), the episode of Nine Temples finally ended. The ancestral temple complex was restored to the old system, and Ruizong was able to build a temple. This construction history, which is full of subtle considerations of etiquette and personal sustenance, has hardly left any trace in the current ancestral temple, but its meticulous and detailed design process has enabled us to re-understand the operation mode of China’s ancient national project.

Ming Shizong’s idea of changing the temple system has gone through five years from concept to realization. The new temple system is not the arbitrary result of the king, but a mature operation from determining the planning principle, evaluating the conceptual scheme, organizing on-site reconnaissance, submitting the formal design, deepening the comparison and selection, and several rounds of adjustment until the final construction. The design data left in this process has promoted our understanding of the architectural evolution of Beijing ancestral temple. However, the in-depth participation of officials such as Xia Yan shows their architectural engineering accomplishment, which fills the gap in the traditional cognition that there is no architect in ancient architectural design in China.
