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.

Institute of Neuroscience, Chinese Academy of Sciences: There is the best research soil here.

  At the age of 30, Serina Liu became the head of a research team at the Institute of Neuroscience, China Academy of Sciences.

  It is the dream of young people doing scientific research to set up their own research groups. Serina Liu himself had never thought that this day would come so quickly.

  In 2018, the news that the world’s first somatic cloned monkey was born in the Institute of Neurology, Chinese Academy of Sciences was released, which was one of the most remarkable developments in the global scientific community that year. Behind this major breakthrough is a young team of "Dr. Tu", and Liu is really one of them.

  Serina Liu stood out from the crowd thanks to the innovative mechanism and system of Institute of Neurology, Chinese Academy of Sciences. After years of follow-up interviews with the Institute of Neurology of the Chinese Academy of Sciences, the reporter found that the best scientific research soil is accumulating here. After 20 years of exploring the reform of scientific research system, this young research institute is moving towards the ideal of becoming the world’s top scientific research institution. Aiming at the forefront of the world’s science and technology, a lean and efficient research team is marching forward bravely, striving to lead and promote the upgrading of strategic industries with major breakthroughs in basic scientific research, and make contributions to building an innovative country and building a world science and technology power.

  To grow up "lining", not talent "hat"

  In 2010, Serina Liu was admitted to the Institute of Neurology of Chinese Academy of Sciences from Shandong Normal University to study for a master’s degree, and joined the macaque platform hosted by her tutor Sun Qiang. In 2016, Dr. Serina Liu graduated and published a research paper on genetically modified monkeys with autism in the top international academic magazine Nature. With his academic achievements during his doctoral period, there is no problem in applying for top foreign laboratories. Serina Liu finally decided to stay and continue his postdoctoral research in the institute.

  Go to a good foreign laboratory as a postdoctoral researcher, and after publishing one or two good articles, apply to return to China to be a "thousand young people" — — This is the ideal growth track for most doctors in the field of life sciences after graduation. Moreover, with the "hat" of talents, the support of research funds, preferential policies for settling down and so on can follow. However, if you choose to go abroad, most of you can’t continue the project of "making cloned monkeys", and you can only do "short, flat and fast" projects in other directions.

  The purpose of Serina Liu’s stay is to continue to work on making monkey models of brain diseases. He knows that this is the breakthrough direction of the key layout of the Institute of Neurology of the Chinese Academy of Sciences, and he is eager to join in it. One of the main reasons why most brain diseases can’t be effectively treated is that the current mouse model for developing drugs is far from that of humans, and most of the drugs developed are ineffective or have side effects when tested in humans. The production of disease model monkeys will bring unprecedented bright prospects for the mechanism research, intervention, diagnosis and treatment of brain diseases.

  Muming Poo, an academician of the Chinese Academy of Sciences and director of the Institute of Neurology, also convinced Serina Liu that only by breaking through the somatic cell cloning technology of nonhuman primates can we truly solve a series of shortcomings faced by macaques as experimental animals, establish a competitive advantage in brain science research in China and become an international leader.

  "The domestic scientific research conditions are different, and the state pays more attention to personnel training. It is an inevitable trend to make more and more world-leading achievements in China." Serina Liu said, "In my opinion, no place can provide me with better opportunities and support than the nerve center."

  "For a young scientific research talent who gives up studying abroad and is willing to stay at home to challenge major scientific problems, if the challenge fails, can we correctly evaluate his ability and let him still have a good development prospect?" When Sun Qiang led the team led by Serina Liu to experience numerous failures and achieved the first major breakthrough in the world’s somatic cloning of monkeys, Muming Poo raised a question worth pondering.

  In July 2018, more than eight months after the birth of the cloned monkey, Serina Liu left the station early after only one year of postdoctoral work in the Institute of Neurology, Chinese Academy of Sciences, and was officially hired as a researcher and became a research team leader of the Institute of Neurology.

  In the past year, Serina Liu has obtained the same research start-up funds and operation funds as other researchers in the institute. His laboratory is 130 square meters, equipped with five employees, and recruits one or two students every year. "This is enough for a research group that has just started." Serina Liu said that he intends to complete the optimization and efficiency improvement of somatic cloning monkey technology in three to five years, and at the same time, open some interesting topics step by step, such as the neurobiological mechanism of puberty initiation in primates.

  Serina Liu’s growth trajectory is just one of the cases in which the nervous system does not take the usual path and innovates the system and mechanism.

  Speak by skill, not by title.

  "The research team leader recruited by the Institute of Neurology only looks at whether there is a good job, not whether there is experience in studying abroad." When Serina Liu hesitated to go abroad, Muming Poo’s words reassured him.

  This is not an exception, but a performance-centered talent use and evaluation system that the Institute of Neurology has been insisting on for many years.

  In 1998, the CPC Central Committee and the State Council made a major decision to build a national innovation system, and decided that the Chinese Academy of Sciences would launch a pilot project of knowledge innovation. As one of the important strategic arrangements of the pilot project, Chinese Academy of Sciences established the Institute of Neuroscience in November 1999, with Muming Poo as its director. At that time, the situation could be called "being ordered at a critical moment", and Muming Poo became the first foreign director of the Chinese Academy of Sciences.

  "Only by establishing a brand-new institute of modern scientific research system and using a new system and mechanism can we attract talents." At the beginning of its establishment, Muming Poo made up his mind to innovate the operation and management of scientific research institutes and vigorously reform the traditional scientific research evaluation and incentive system. His goal is to establish a top scientific research institution which is recognized by international peers and whose operation mode can be replicated and popularized in China.

  Since 2003, the Institute of Neurology has taken the lead in introducing an international scientific research evaluation system among national scientific research institutes. Here, heroes don’t ask the source, talents don’t have the distinction of "foreign soil", and researchers should speak by skill, not by title. Even well-known experts should abide by the strict assessment requirements of the institute, and even without a diploma, they can be hired as deputy senior professional and technical posts. All work is to create a good ecological environment for scientific and technological innovation.

  When receiving the olive branch from the nerve, Sun Qiang was still a little-known university lecturer. He graduated from Inner Mongolia University for Nationalities with no overseas study experience. At the age of 36, he had just been awarded the deputy senior title and experienced the failure of developing transgenic monkeys. He once considered whether to give up the research on nonhuman primates. At an academic conference, I learned about Sun Qiang’s practical foundation and technical level for many years. Muming Poo introduced him as a full-time senior engineer and entrusted him with the task of building a research platform for nonhuman primates.

  To work here, Sun Qiang only made one condition to Muming Poo: to bring two veterinarians with only junior college education. Although their education is not high, they are a very important part of the scientific research team and need spirituality and concentration to achieve the ultimate.

  At the beginning of 2018, the world’s first cloned monkey "Zhong Zhong" and "Hua Hua" cultivated by Sun Qiang’s team appeared in Cell magazine. This achievement, independently completed by scientists in China, is known as "a milestone breakthrough in the field of biotechnology in the world". The birth of the cloned monkey also proves that China has reached a stage from gradual and incremental innovation to a major breakthrough.

  Are "Dr. Tu" and "Dr. Tu" not as good as those who have drunk "foreign ink"? Obviously not. Major breakthroughs, such as synthetic insulin, have been made by local scientists in China, most of whom are young scientists. In Muming Poo’s eyes, young people are the most innovative when they are 25 to 35 years old, but many excellent students go abroad as postdoctoral fellows, and devote the time that they can do experiments wholeheartedly to foreign laboratories in order to become "foreign talents" and get the talent "hat" smoothly.

  "It seems that if you don’t go abroad, you can’t find a good job, and you don’t pay enough attention to the local talents you cultivate. This kind of employment orientation must be changed." Muming Poo regrets, "truly successful people don’t necessarily have to go abroad. It is very important to keep excellent doctoral and postdoctoral students in domestic first-class scientific research units and give them opportunities for innovation. There must be various mechanisms to encourage such talents. "

  This is what the nerve has been trying to do. Under the leadership of Muming Poo, the Institute of Neurology has continuously deepened the reform of mechanism and system, and made in-depth and extensive explorations and attempts in the innovation of system and mechanism such as postgraduate training, team research to promote cross-integration, selection and promotion, and evaluation.

  Yan Wang, secretary of the Party Committee of the Institute of Neurology, summed up the basic principles of talent work in the Institute of Neurology — — Provide a relatively stable scientific research environment, so that scientists can focus on research work; Carry out strict international assessment and implement a benign flow mechanism; Guide researchers to resist pressure and temptation, so that young scientists can work in a down-to-earth manner.

  With these three rules, the breakthrough is ahead, and all it takes is time. Of course, it is very important to delve into major issues.

  Stick to "big problems" instead of "short-term" topics.

  "Big problem" is a key word deeply rooted in the culture of the Institute of Neurology.

  It is precisely because of aiming at major scientific problems that the non-human primate research platform is built and perfected. In fact, since 2002, many research institutions in the world have started the research on somatic cell cloning of nonhuman primates. In 2010, Mitalipov, a scientist from Oregon Primate Research Center, led a team to successfully transplant cloned monkey embryos, but unfortunately, the success failed, and the embryos ended in abortion after 81 days of development.

  However, due to the high investment cost and long output cycle of primate research, at first, many researchers who took mice as experimental objects inside and outside the Institute of Neurology were not optimistic about the investment in somatic cloned monkeys. In 2009, Muming Poo made a public opinion, and used the director’s fund layout to build a non-human primate research platform. That year, the Chinese Academy of Sciences tried out the only stable support policy for the whole hospital system, including the director’s fund. Since 2012, the non-human primate research platform project has been supported by Chinese Academy of Sciences. The background is that the Chinese Academy of Sciences, as a national strategic scientific and technological force, launched the strategic pilot science and technology project (Class B) "Study on Brain Function Linkage Map" in this year. This special project is one of the first five Class B pilot projects initiated by the Chinese Academy of Sciences, which is earlier than the start time of related "brain projects" in the United States, Japan and the European Union.

  In 2014, the Chinese Academy of Sciences launched the "First Action" plan, which outlined the reform of the classification of research institutes and comprehensively promoted the reform of institutional mechanisms. In the same year, based on the Institute of Neurology, the Center for Excellence and Innovation in Brain Science of Chinese Academy of Sciences was established, becoming one of the first four centers for Excellence and innovation established by Chinese Academy of Sciences.

  In 2015, during the planning of "China Brain Project", scientists in China put forward a "one body and two wings" architecture, that is, the neural principle of brain cognition as the "main body" and the new means of diagnosis and treatment of brain diseases and the new brain-like intelligent technology as the "two wings". The Chinese Academy of Sciences responded quickly and planned the coordinated development of brain science and brain-like research. The Center for Excellence and Innovation in Brain Science and Intelligent Technology, jointly planned by Institute of Neurology and Institute of Automation, was formally established in this year.

  Major changes have spawned major outputs. Perhaps coincidentally, on November 27th, 2017, the 18th anniversary of the establishment of the Institute of Neurology, the somatic cloned monkey "Zhongzhong" was born. In Muming Poo’s view: "The reason for our success is that we saw that this problem can be solved and stuck to it, while most foreign laboratories gave up. Our success is due to the cohesion of a group of cutting-edge talents. "

  "If you want to make a breakthrough scientific discovery, you must do important problems. I hope that the teachers and students of the Institute of Neurology have the confidence to do the best work, have the confidence and courage to do important problems, and eventually make breakthrough scientific discoveries. " Muming Poo is convinced. The "baton" of evaluation is also guiding everyone to explore innovative major scientific issues in line with the direction of national strategic development, rather than simply doing the topic of "fast, safe and easy to publish articles".

  At the end of November every year, it is the "big gathering" of the Institute of Neurology. After the establishment of the Center for Excellence and Innovation in Brain Science and Intelligent Technology, this tradition continued and became the "big gathering" of the whole center, and the performance evaluation of the year was carried out at the same time as academic exchanges. The evaluation results are the basis for researchers to apply for annual research funds and adjust performance allowances, and directly affect their funding and promotion opportunities.

  The results of performance evaluation are divided into three grades: A, B and C. Members who have been rated as C for two consecutive years will be required to make rectification, and the annual performance allowance will be stopped during the rectification period; Members who have been rated as C for three consecutive years will be asked to withdraw; Members who have been rated as A for two consecutive years will be given priority in promotion assessment.

  Yan Wang remembers that when it was first implemented, the impact was great. Some researchers can’t figure out: why did they get a C in the evaluation because they have sent so many papers with high impact factors? Because the evaluation criteria are different, the "paper-only" evaluation system has been broken since the end of 2015, focusing on the contribution to the team’s key projects, excluding the results unrelated to the team’s projects; There are significant innovative achievements in the key areas of the center layout; The investment in interdisciplinary communication includes multi-unit "squatting" teaching and research, and guiding dual-tutor graduate students.

  What are good results and big results? What kind of achievement is a major breakthrough? "It is a major breakthrough to open up new scientific research fields and achieve milestones in the original scientific research fields. Looking around the world, the world’s top scientific research institutions have such achievements. Every scientific research field has well-known major unsolved problems, and it is the real leader in this field to continuously make major breakthroughs in one field. " Muming Poo said.

  It is necessary to "explore freely" and "tackle key problems by team"

  "It has been 5 years since I returned to China. Let’s see when I can get the first clinical approval." On July 8, Yang Hui, a researcher at the Institute of Neurology, wrote this sentence in a circle of friends, with a smiling expression of high morale.

  In 2014, 29-year-old Yang Hui became the youngest researcher in the Institute of Neurology, and served as the leader of the primate disease model research group and doctoral supervisor. "90% of rare diseases are incurable. Can we do something with gene editing?" Yang Hui said that rare diseases are actually not rare. There are more than 7,000 rare diseases found in the world, with more than 300 million patients, more than cancer patients. The goal of him and his team is to develop more efficient and safer gene editing tools and build a research and development platform for treating rare diseases. "The first gene drug in China will not be too far away".

  In the first half of this year, Yang Hui’s research group had a bumper harvest, and published two papers in Science and Nature. It was the first time in the world to confirm the off-target effect of single-base gene editing, and then further repaired the off-target "loophole" and established a new generation of single-base gene editing tools. The young researcher said frankly: "I’m still very uneasy, and I’m most worried about disappointing the students’ efforts day and night. Teacher Pu is still helping us to change articles over and over again during the Spring Festival holiday. Thank you for your efforts and hope that the results will benefit China patients as soon as possible. "

  The birth of somatic cloned monkeys undoubtedly brought Yang Hui closer to her dream. Starting from 2018, a monthly seminar on cloned monkeys will be held. In addition to the main personnel of the primate platform, many research groups of the Institute of Neurology will participate, expecting to bear more innovative fruits in deep cross-integration. Sun Qiang said that on the basis of successfully constructing the world’s first batch of somaclonal monkeys with dysrhythmia, more efforts are being organized, and the efforts of the Institute, the Center of Excellence and even the whole country are gathered to develop a variety of disease model monkeys and tool monkeys developed by somaclonal monkey technology as soon as possible. "Many research groups in the Institute have cooperated with us."

  In Muming Poo’s view, at present, breakthroughs in most fields require cooperative research, and establishing a concise and efficient research team is the key to a major breakthrough. "The biggest challenge in the biological science community at present is to establish an effective research team." The molecular mechanism and variety design of synthetic bovine insulin with full activity, high yield and high quality rice are not the results of individual combat. To make breakthrough work on major issues requires the team spirit of sincere cooperation, hard work and perseverance of each member, and puts the task and goal of team research above personal gains and losses.

  This is also the first-class scientific research culture that Muming Poo has always advocated, and the first-class scientific research institutions should have. "Looking for the development direction of the frontier of science must be free to explore. However, with the development of science and technology, it is difficult to make a real breakthrough only by individual’s free exploration. Therefore, it is an inevitable trend for young and middle-aged scientists to abandon the limitations of fame and fortune, cooperate with each other and jointly answer important scientific questions. "

  At the beginning of its establishment, the Institute of Neurology insisted on joint team research as the core way to solve major problems, and actively explored the establishment of scientific research systems and mechanisms that take into account collective goals and personal interests, demand orientation and free exploration. Here, most of the personal interests of scientific researchers are respected, most of their personal expertise is found, and valuable and distinctive frontier research fields are basically covered.

  Muming Poo has a profound understanding of the training methods of Chinese and Western scientists, and he hopes to promote the establishment of a new scientific culture in the nerve center and cultivate intellectuals who inherit China’s traditional values. In his view, Chinese researchers should have the spirit of selflessness, and more importantly, they should have the feeling of "worrying about the world first, and enjoying the world later" of China traditional intellectuals, so as to serve the country with scientific and technological achievements.

  "Please don’t buy things you don’t need in the near future. I am very seriously opposed to the idea of spending all the unspent funds before the end of the year. If we can’t use up the money, it means that we don’t need it. We must return it to the Chinese Academy of Sciences or other sources. This is the correct attitude of a scientist with social responsibility. " Muming Poo once sent an email to the research group leader in the institute.

  In his view, it is a basic social conscience that researchers should use research funds cautiously. The level of scientists is expressed by ideas and innovation, not by the latest models of instruments they have. The wind of "grabbing" resources once appeared in academic circles is a waste to society. The practice of the Institute of Neurology also proves this point. The rapid development depends not on the input of resources, but on the ideal of building a world-class scientific research institution and persisting in promoting the reform of the system and mechanism.

  At the beginning of his tenure as director of the Institute of Neurology, Muming Poo once put down his grandiloquence: "I have never been so confident in successfully establishing a world-class research institute on the land of China. This will be a research institute that will be recorded in the history of science in China. As the first director of the Institute of Neurology, I am determined to do my best to turn the Institute of Neurology into a fertile soil where the seeds of scientific invention will sprout, take root and blossom. "

  This year, 71-year-old Muming Poo will soon witness the 20th year of this research institute, which has devoted countless efforts to it, and complete another major turn. In the near future, it will continue to complete its mission and responsibility under the name of "Center for Excellence in Innovation of Brain Science and Intelligent Technology of Chinese Academy of Sciences".

  Innovation, innovation, and innovation.

  Fusion, fusion, re-fusion.

  This is the result of the times and the general trend. At present, the research of brain science and intelligent technology is facing unprecedented development opportunities. After 20 years of intensive cultivation, a research team led by outstanding scientists and with outstanding young scientists as the main body has become increasingly mature and has become a main force in the research of brain science and intelligent technology in China. After 20 years of reform and innovation, the rivers crossed, the bridges crossed and the roads traversed have been integrated into the great process of China’s scientific and technological innovation to overcome difficulties and become a cornerstone to consolidate the innovation-driven development strategy.

How to choose electric car charger?

With the popularity of electric vehicles, electric car charger has become an indispensable accessory for every electric vehicle user. However, there are many kinds of chargers in the market. How to choose a charger that suits you? The following will be popular science for everyone from several key aspects.

* * First, understand the battery type of electric vehicles * *

First of all, we need to know what kind of batteries our electric cars use, such as lead-acid batteries and lithium batteries. Different types of batteries have different requirements for chargers, so the choice of chargers must match the battery type.

* * Second, pay attention to the power and current of the charger * *

The power and current of the charger directly affect the charging speed and battery life. The higher the power, the faster the charging speed, but it may also cause damage to the battery. Therefore, when choosing a charger, we should choose a charger with moderate power and stable current according to the battery capacity and our own needs.

* * Third, pay attention to the safety performance of the charger * *

Safety performance is an important factor that cannot be ignored when choosing a charger. A high-quality charger should have multiple protection functions such as overcharge, overdischarge, overheating and short circuit to ensure the safety during charging. In addition, the charger with national certification mark should be selected to ensure product quality.

* * Fourth, consider the portability and ease of use of the charger * *

For users who often need to go out to charge, the portability and ease of use of the charger are also factors to be considered. Lightweight and compact chargers are easy to carry, while simple chargers can lower the use threshold.

* * 5. Understand the brand and reputation of the charger * *

Brand and word of mouth are important references when choosing a charger. Well-known brands usually have more advanced technology and stricter quality control, while good reputation means that products have been recognized by users in practical use.

To sum up, choosing a electric car charger that suits you needs to be considered from many aspects. I hope the above popular science content can help you to choose electric car charger better.

China’s foreign trade scale broke the 40 trillion yuan mark for the first time.

Xinhua News Agency, Beijing, January 13th (Reporter Zou Duowei) China’s foreign trade scale has reached a new level. According to data released by the General Administration of Customs on the 13th, the total import and export value of China’s goods trade in 2022 was 42.07 trillion yuan, an increase of 7.7% over that in 2021, and it maintained its position as the largest country in goods trade for six consecutive years.

Among them, exports continued to maintain a relatively high growth rate, totaling 23.97 trillion yuan, up 10.5% year-on-year; Imports reached 18.1 trillion yuan, a year-on-year increase of 4.3%.

Lu Daliang, spokesman of the General Administration of Customs, said that in 2022, in the face of complicated and severe domestic and international situations, China’s foreign trade withstood the impact of multiple unexpected factors and achieved steady growth on the basis of the high base of the previous year. The total value of imports and exports exceeded 40 trillion yuan for the first time, making positive contributions to the steady economic development.

From the perspective of trade patterns, general trade has grown rapidly and its proportion has increased. In 2022, China’s general trade import and export was 26.81 trillion yuan, up 11.5%, accounting for 63.7% of the total import and export value, up 2.2 percentage points from the previous year.

From the perspective of trading partners, China and ASEAN have closer economic and trade exchanges, with the import and export scale reaching 6.52 trillion yuan, an increase of 15%. ASEAN continues to be China’s largest trading partner. In the same period, China’s import and export to countries along the Belt and Road increased by 19.4%, accounting for 32.9% of China’s total foreign trade, up by 3.2 percentage points; Imports and exports to other RCEP member countries increased by 7.5%.

From the perspective of foreign trade subjects, private enterprises have performed well. In 2022, there were 598,000 foreign trade enterprises with import and export performance in China, an increase of 5.6%. The proportion of import and export scale of private enterprises reached 50.9%, an increase of 2.3 percentage points, and the annual proportion exceeded half for the first time.

From the perspective of commodity types, the main products have stable supply and demand and sufficient advantages. In 2022, the import and export of mechanical and electrical products in China was 20.66 trillion yuan, up 2.5%, accounting for 49.1% of the total import and export value. Among them, the export of solar cells, lithium batteries and automobiles increased by 67.8%, 86.7% and 82.2% respectively. In addition, the total import of energy products such as crude oil, natural gas and coal was 3.19 trillion yuan, an increase of 40.9%, accounting for 17.6% of the total import value.

"Overall, in 2022, China’s foreign trade achieved a new breakthrough, and the scale, quality and efficiency of imports and exports increased simultaneously, and the results were hard-won." Lu Daliang said that looking forward to this year, while facing up to the difficult challenges facing foreign trade development, we should also see that China’s economy is strong in resilience, great in potential and full of vitality, and the fundamentals of long-term improvement remain unchanged. This year, the economy is expected to rebound overall, and we must more firmly promote the confidence of stable scale and excellent structure of foreign trade.

Can the transaction limit of bank card be adjusted? How to adjust?

In the banking field, the transaction limit of bank cards can be adjusted.The feasibility and specific way of this adjustment depends on many factors, including bank policies, card types, customer needs and authentication.

First of all, different types of bank cards, such as debit cards and credit cards, may have different adjustment rules and ranges of transaction limits. For debit cards, usually the transaction limit mainly includes daily withdrawal limit, transfer limit and so on. The transaction limit of credit card may include consumption limit, cash withdrawal limit and so on.

The original intention of the bank to set the transaction limit is mainly to ensure the safety of customers’ funds and prevent large capital losses caused by stolen bank cards or misoperation. However, when customers have special needs, such as large transactions, they can apply for adjusting the limit.

There are several ways to adjust the transaction limit of bank cards:

1. Online banking: Many banks provide online banking services. Customers can log in to their online banking accounts and find the function of adjusting the trading limit in the relevant setting options. In this way, customers can operate according to the prompts, and usually need to input some verification information, such as SMS verification code and dynamic password.

2. Mobile banking: Similar to online banking, mobile banking applications usually have the function of adjusting transaction limits. Customers only need to open the bank’s application on their mobile phones and follow the instructions.

3. Bank counter: This is a more traditional but direct and effective way. Customers can bring their valid identity documents and bank cards to the bank counter and apply to the staff for adjusting the transaction limit. The staff will handle it according to the needs of customers and the regulations of the bank.

It should be noted that no matter which way the transaction limit is adjusted, the bank may strictly verify the identity of the customer to ensure that it is the true will of the customer. In addition, the adjusted trading limit is not unlimited, and the bank will set it reasonably according to the customer’s credit status, source of funds and other factors.

Take the adjustment of debit card and credit card transaction limit of a bank as an example to provide you with a simple comparison table:

Card type Adjustment mode Common initial limit Adjustable upper limit debit card Online banking, mobile banking, counters Withdraw 20,000 yuan every day and transfer 50,000 yuan. According to customer demand and bank evaluation, it generally does not exceed 500,000 yuan. credit card Online banking, mobile banking, customer service hotline Spend 50,000 yuan and withdraw 10,000 yuan. According to the customer’s credit status and card usage, it generally does not exceed 2 times of the credit limit.

In short, the transaction limit of bank cards can be adjusted, but customers should make reasonable choices according to their actual needs and risk tolerance when applying for adjustment, and at the same time abide by the relevant regulations and procedures of banks.

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.

Ming jiajing dynasty Beijing ancestral temple

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:

Table 1 The design data of Taizong Temple mentioned in Xia Yan’s recitation on October 23rd, 13th year of Jiajing (1534) and the design data of each group of temples deduced from it.

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.

200 dollars overlooking Pyongyang! This extravagant North Korean tourism project is on fire.

CCTV News:In recent years, the tourism industry in North Korea has developed rapidly, and various theme tourism projects are increasing day by day. There is an emerging tourist attraction outside the suburbs of Pyongyang, that is, the Merrill Lynch Aviation Club, which was put into operation in 2016. Guests who come here can take a glider to enjoy the beautiful scenery of Pyongyang and enjoy the pleasure of high-altitude viewing.

Six tourist routes launched by Merrill Lynch Aviation Club

 Merrill Lynch Aviation Club has six routes to choose from, including Wanjingtai, Science and Technology Hall and Future Scientist Street in Pyongyang. In addition, guests can choose customized routes according to their own preferences, and the prices vary from high to low from $200 to $20 according to different routes.

 

 Before flying, you need to change your designated flight suit, wear a helmet and accept safety inspection.

Merrill Lynch Aviation Club has more than 20 ultra-light aircraft made by North Korea for tourism, including runway, bleachers and office buildings. Air travel is carried out from early spring to late autumn. The flight route from the aviation club to Wanjingtai is the longest, with a flight time of more than 40 minutes and a price of 200 US dollars. It only takes more than 5 minutes to hover over the airport once, and the price is 20 dollars once. According to local laws and regulations, journalists are not allowed to take equipment to shoot while flying. After the flight, the reporter felt that the flight was relatively stable and Pyongyang was beautiful. Other tourists also praised the flying experience.

 

 Merrill Lynch Aviation Club visitors:Today, when I was flying, I saw the scenery of Pyongyang from the sky. It was so beautiful.

Merrill Lynch air club touristsI feel very cool. I am not flying in a plane from other countries, but in a plane made by ourselves. I am very happy to see the scenery of our country from the air.

Although the price of the aviation club is not cheap for the local people in North Korea, many people still come to experience it. Some units will also organize employees to visit Merrill Lynch Aviation Club.

Li Yinzheng, waiter of Merrill Lynch Aviation Club:We will do our best to provide more and better services for foreign guests and the Korean people in the future.

Personalized flight route, meticulous and considerate service. You can have a panoramic view of Pyongyang by flying in Merrill Lynch Aviation Club. And it will definitely become the next tourist attraction after coming to North Korea.
