Israel’s new naval commander, Eli Marom

　　The "first" in the army

　　At the end of October, Israel’s new naval commander, Aili Maroum, officially took office. Unlike his predecessor, as well as officers of all arms such as the Israeli navy, Ali has a distinctive China silhouette, and his face, skin color and hair are quite "China-like", so that he looks like a China at first glance. It turns out that Ellie is of China descent. It is the first time in Israeli history that a person of China descent holds such a high military post.

　　On October 8th, Ali Maroum was officially appointed. On the same day, Israeli Defense Minister Barak, Israeli Chief of Staff Askin Naz and others held an appointment ceremony for him. Barak admired Ali and had high hopes, because he was interested in David, the former naval commander. Ben? Basat’s performance in the Israel-Lebanon war was "extremely dissatisfied", and he always wanted to "take off" the admiral who had worked for four years, but he was constrained by the relations between all parties and did not do it easily. This time, Barak finally made a decision. He patted Ali on the shoulder and said, "Work hard, make up for the losses caused before, and rebuild the elegance and glory of the Israeli navy." Askin Naz also encouraged Ali: "It’s up to you now!"

　　"Alternative" makes extraordinary achievements.

　　The 52-year-old Aili’s grandfather is a native of China, and her grandmother moved to China from Russia. Aili’s father fled from Germany to China in World War II, met Aili’s mother and got married. Seven years after the establishment of Israel, the couple returned to Israel to settle down, and Ali was born here.

　　Because Ellie’s oriental characteristics are obvious, she has been called "Chinese" since she was a child. This nickname comes from the English word "Chinese" (from China). From the time he was sensible, Ali realized that his appearance was "different", but he didn’t resent being called "Chiney". Even when introducing himself to strangers, he took the initiative to say "My name is Chiney". According to Ali’s classmates, he was always at the top of his class and had a strong personality. After joining the army, Ali’s strong personality became more prominent, which made him get promoted continuously. One of Aili’s colleagues said: "The fact that he looks different forced Chiney to constantly show people that he is better, so that he quickly became one of the best."

　　Through hard work, Ali became the commander of Haifa naval base in northern Israel from a little-known naval engineer, and became the deputy commander of the navy. In addition, he has served as the Israeli military representative of the United States-Israel Joint Staff and the Israeli military attache in the United States.

　　Be questioned for no reason because of one’s ancestry

　　After Ali was appointed as the commander of the navy, it caused great repercussions in Israel’s domestic public opinion and people. On the same day, the Israeli media reported the incident with headlines such as "Israel has an China as the commander of the navy" and "the new commander of the navy comes from China", which was quite confusing, and some netizens who didn’t understand the situation even gave a puzzled exclamation. Many public opinions have expressed enough confidence in Ali’s ability to reorganize and strengthen the Israeli navy, but some people have questioned his appointment as commander of the Israeli navy, and some even point out that he is a quarter of China origin.

　　Little information: Israeli navy

　　Due to the persistent tense military and political situation in the Middle East, Israel has always attached great importance to the navy and developed it as an independent service for many years. By the beginning of 2003, the Israeli navy had a total of 65,000 people and more than 70 ships including submarines, making it an important maritime force along the Mediterranean coast.

　　Organization

　　The highest officer of the Israeli navy is the commander of the navy. Through his headquarters (located in Haifa), he exercises daily leadership over the naval forces: he is responsible for the naval combat readiness, development, organization of combat training and material and technical support, and is directly under the leadership of the Chief of Staff of the Israeli Armed Forces. The headquarters consists of six departments: combat department, training department, reconnaissance department, cadre department, communication department and logistics department. The organizational structure of the navy also includes several headquarters, namely, the naval combat force command, the missile force command, the submarine force command, the patrol force command, the coast guard command, the naval base and the naval berth command. ·

　　All the ships of the Israeli navy are organized into two clusters: the Mediterranean cluster and the Red Sea cluster. The submarine sub-fleet, the light frigate sub-fleet and the missile boat sub-fleet are the main naval fleet.

　　By the beginning of 2003, the Israeli navy’s combat formation consisted of four sub-fleets of combat ships (one submarine sub-fleet, one light frigate sub-fleet and two missile boats sub-fleet), six combat boat detachments (five escort boats and one missile boat and escort boat detachment), one base patrol squadron, two helicopter battalions, two independent naval battalions (Marine Battalion and Destruction Reconnaissance Battalion) and 12 coastal battery companies. At present, there are three Israeli naval bases, namely Haifa base, Ashdod base and Eilat base. In addition, it has several berths, such as Aka, Art Park Jung Su and Ashkelon. Except Haifa base, other ground facilities are located in the Mediterranean Sea.

　　Existing equipment

　　According to the latest information, the Israeli navy currently has six conventional submarines of Dolphin and Gaelic class, three light frigates (Saar-5 class), 20 missile boats (Saar-4 class and Saar-4.5 class) and 33 escort boats (Dabbour class, Super Debora class and Sheldag class). As an underwater killer of the Israeli navy, the Dolphin class submarine is equipped with 533mm and 650mm anti-submarine torpedo tubes and UGM—84C Saber-Harpoon anti-ship missile. According to western military analysts, the boat is also equipped with cruise missiles developed by Israel itself.

　　In addition, the naval air force is equipped with three base patrol aircraft and 41 combat helicopters. The coastal artillery has 24 shore guns and 60 anti-aircraft guns with a caliber of more than 20 mm.

　　In the event of war, the number of sub-fleets and formations of the Israeli navy will not change at the beginning, but the number of warships and combat boats can be increased by 21 after 30 days and nights. With various mobilization measures, the total number of Israeli navy will reach 115,000.

　　Personnel training

　　Israeli naval officers are usually trained by the Naval School in Haifa, which is attended by active naval sergeants and those who have successfully graduated from the maritime school in Akka. The training period is two years, and graduates will be awarded the rank of lieutenant. About 50 officers graduate from this school every year.

　　The Naval Training Center in Haifa is also a place to train command cadres and engineering and technical cadres for the navy, mainly to train junior technicians working on ships. In addition, graduates from the merchant marine school in Tyre-Avev and Ashdod can also be enlisted in the navy.

　　The training of middle-level officers in command and command positions is usually carried out in their own command colleges and military academies in NATO countries.

　　Its campaign tactical training is carried out according to the plan of the General Staff of the Israeli Armed Forces. The main purpose of training is to teach and improve the skills of organizing the coordinated action of various arms of the navy. One of its contents is the "Reliable Mermaid" exercise jointly conducted with the US and Turkish navies. The exercise is held regularly in the eastern Mediterranean, with the aim of constantly improving the coordinated actions of the three navies in the process of coordinated search and rescue operations. When organizing the training of staff officers, they widely use computer equipment, including equipment that can simulate the combat operations of all parties and equipment that can improve the training level of commanders with reduced military input.

　　Future development

　　Within the framework of the "Army-2010" package to re-equip the national armed forces, Israeli leaders paid special attention to the modernization of the navy. The improvement of naval forces is carried out from the following aspects: new surface ships and submarines are added to the navy, equipped with modern weapons and technical weapons, and the modernization of various ships is realized. According to this plan, Israel will build six "Super-Debora" class escort boats and two "Sheldag" class escort boats. Among them, the first boat was put into service in the second half of 2003. Moreover, Israel’s Ministry of National Defense plans to buy another seven similar escort boats.

　　At the same time, the Israeli navy is negotiating with the American shipbuilding company "ingels" for the purchase of four light frigates. If the negotiations go smoothly, the first batch of ships will be installed as navy in 2007. According to the analysis of international military analysts, it is very likely that the Israeli navy will be equipped with cruise missiles with a flight distance of about 200 kilometers. The missile was developed by a subsidiary of the Israeli aviation industry giant Konzern.

　　According to the estimation of international military analysts, the new naval plan will further improve the combat capability of the Israeli navy and consolidate its dominant position in the navies of Arab Muslim countries in the Near and Middle East.

　　[Great motherland, unforgettable songs].

　　"Splendid rivers and mountains are picturesque, and the motherland is building a cross-horse. It’s a great honor for me to be an oil worker and travel around the world wearing an aluminum helmet … …” This heroic ode to oil workers is not only a clarion call to encourage oil workers from generation to generation to join in the construction of the motherland, but also an overall portrayal of the outstanding heroes of the working class in China. Although it was written more than half a century ago, it is still so exciting and exciting to sing today.

　　The composer Qin Yongcheng (1933— 2015) is the first generation composer trained in New China. During more than half a century’s creative career, he has created a large number of musical works with high artistic achievements and wide social influence, such as the song "I offer oil for the motherland", "Chairman Mao travels all over the motherland", My People，My Country, vocal concerto "Haiyan", symphonic poem "Two Little Cowboys" and movie music "Entrepreneurship" and "Marshal and Soldiers". He made great contributions to the music, art and education in our country all his life.

　　Three days with the "Iron Man"

　　In 1964, a notice brought Qin Yongcheng into close contact with Li Jiefu, a famous composer and president of Shenyang Conservatory of Music. It was this notice that made him have an indissoluble bond with oil workers all his life. In March this year, China Musicians Association organized some composers to experience life in Daqing Oilfield and created a batch of works reflecting oil workers. Dean Hijacking also received a notice, asking him to report to Sarthou, Heilongjiang Province on March 20th. After receiving the notice, the dean of the robbery immediately made preparations for leaving. Due to physical reasons, the college is going to find a young man to accompany the dean of the robbery to "go north". At the suggestion of the dean of the robbery, Qin Yongcheng will accompany him. Unfortunately, Qin Yongcheng was suffering from a high fever and had been in bed for three days. Upon hearing this, Dean Hijacking personally visited Qin Yongcheng’s home and told him to rest at ease for illness. In the face of this rare opportunity, Qin Yongcheng looked forward to his early recovery. Although his fever had gone down the next day, he was still very weak, and insisted on accompanying Dean Jiefu.

　　On the evening of 19th, Qin Yongcheng got his wish and boarded the train to the north. In the car, Qin Yongcheng finally put forward the question that was hidden in his heart: "Where are we going to Sarthou?" Dean Hijacking told him quietly: "Sarthou is a big oil field, called Daqing Oilfield, and it is still confidential." After moving to Daqing, Qin Yongcheng lived with many famous musicians such as Lv Ji, Qu Wei, Wang Xin, Zhang Lu and Jiefu in the guest house of Daqing Petroleum Command.

　　Since the next day, the oil field has arranged courses for musicians to introduce oil-related knowledge, from exploration and drilling to oil production and refining for ten days, with one content per day. Ten days later, the oilfield arranged for them to experience life in the first line. Qin Yongcheng, Jiefu and Wang Xin (songwriters of "Singing the Motherland") were assigned to the "1205 Hero Drilling Team" with Wang Jinxi, the "Iron Man", and lived together with the "Iron Man" for three days. During this period, Wang Jinxi told Qin Yongcheng that when he held a People’s Congress in Beijing in 1959, he saw that the buses in Beijing were in a heavy mood because of lack of oil and carrying gas bags. He also listened to him tell the story of the Daqing Petroleum Congress. In the spring of 1960, Wang Jinxi’s drilling team was in Yumen Oilfield. When it was heard that a large oil field had been discovered in the north, the whole country was going to hold a general meeting there, and immediately asked the superior to fight. They said goodbye to their relatives and boarded the train going north in their light clothes. Faced with the harsh climate, hard living and working environment, and poor equipment, oil workers shouted the loud slogan of "if you have the conditions, you should go if you don’t have the conditions" in order to get rid of the label of "poor oil" as soon as possible and break the economic blockade of western hostile forces. "When the oil workers roar, the earth will shake three times."Qin Yongcheng’s soul was strongly shocked and greatly impacted by his earth-shattering fearless revolutionary heroism. Especially in the days spent with Wang Jinxi and his heroic drilling crew, Qin Yongcheng’s understanding of oil workers has been greatly sublimated, and he has a strong emotional resonance. He is determined to create works that can reflect the spirit of oil workers to express his high respect for them.

　　A masterpiece completed in the canteen of the hostel.

　　After three days of experience, Qin Yongcheng returned to the guest house, and the Propaganda Department of the Party Committee of the Oilfield prepared a batch of lyrics reflecting the work and life of Daqing Oilfield and oil workers for them, hoping that composers would compose music for them. After the old composers had chosen the lyrics, Qin Yongcheng also chose them. At this time, a lyric jumped into his eyes, which was written by oil worker Xue Zhuguo, "I offer oil for my motherland." This first-person lyric is vivid and vivid, which vividly depicts the heroic and optimistic mood of oil workers and the fearless revolutionary spirit of fighting against the world. The more Qin Yongcheng watched it, the more he liked it. The more he watched it, the more excited he became. At this moment, he was inspired and full of thoughts. In the canteen of the hostel, he finished writing this work in just 20 minutes.

　　Inspired by the artistic conception of the lyrics, the prelude of the song adopts a fast speed, a lively and elastic rhythm, and a fluctuating melody line, like a train full of oil workers galloping in the splendid rivers and mountains of the motherland, from the northwest of the motherland to the northeast thousands of miles away. Then, the heroic song of the oil workers was introduced: "The beautiful rivers and mountains are picturesque, and the motherland is building a beautiful horse. I am honored to be an oil worker and wear an aluminum helmet to travel all over the world." The melody of the song is broad, fresh and smooth, which vividly depicts the bold spirit of oil workers and the revolutionary optimism full of pride and self-confidence. On the word "kua" of "kua steed", the melody absorbs the elements of rap music and adopts a sliding tone, which is not only in line with the rhyme of Chinese four tones but also forceful, and can better highlight the bold and hearty character of oil workers. These four sentences are lyrical paragraphs, which vividly depict the heroic fighting spirit and optimistic spirit of oil workers moving to the north and south and being at home all over the world.

　　In order to show the dauntless heroism spirit and heroic spirit of oil workers, who are "fearless of heaven, fearless of earth, and fearless of storm, thunder and lightning", Qin Yongcheng treated these two lyrics into short and powerful eight-point dotted notes and syncopated rhythm, which made the music more powerful and dynamic. At the same time, it not only forms a sharp contrast with the previous lyric paragraphs, but also lays a good foundation for the climax of the whole song that appears later.

　　The climax of the song is in the last two phrases, "I contribute oil to my motherland, where there is oil, my home is there". In order to make the climax of the song more prominent and infectious, Qin Yongcheng ingeniously treated the first beat at the beginning of this sentence as a rest, and started the word "I am" from the weak beat to highlight the word "ancestor" in the next section. Then, on the word "oil" for "offering oil", the melody adopts a circuitous upward movement, forming a large-span 10-degree interval in the range. In the last four bars of the song, Qin Yongcheng skillfully used the drawl of China’s traditional opera music for reference. It is worth mentioning that in the first draft of the work, the last four sections are not like this, but after Qin Yongcheng returned to school, he sang the work to friends and students, listened to and adopted everyone’s suggestions, and changed the original last simple melody into the current one-stop drawl. In this way, the music is more infectious and dynamic, which not only depicts the free and easy character of oil workers, but also makes the whole song end in an atmosphere full of optimism and pride. The revised work was published in the journal "Music Life" of Liaoning Branch of China Music Association, which soon became a hero’s ode to oil workers in the north and south of the motherland and inside and outside the Great Wall.

　　The only "composer of oil workers"

　　The first singer of this song, Liu Bingyi, a famous baritone singer of the former Central Orchestra, also played an important role in the promotion of this song. He and Qin Yongcheng also became attached to this song, and it was sung for 50 years. And Qin Yongcheng also started from this song, and successively created a number of excellent works reflecting oil workers. In 1973, as a key project of the Ministry of Culture, Changying filmed a feature film "Entrepreneurship" reflecting the Daqing Petroleum Congress, and specially invited Qin Yongcheng to create music for this film. Qin Yongcheng lived up to expectations, and created a number of well-known songs in his film music, such as Looking at Beijing with deep feelings, Entrepreneurial songs, and The Fragrance of Oil in Tianya Wan Li. Because of Qin Yongcheng’s outstanding contribution to the creation of oil-related music, the vast number of oil workers are familiar with the name Qin Yongcheng and affectionately call him "the composer of oil workers". In 1994, China Petroleum and Natural Gas Corporation (formerly the Ministry of Petroleum Industry) awarded Qin Yongcheng the honorary title of "composer of oil workers", and he was the only composer in China to win this honor. In 1996, China Records Corporation awarded Qin Yongcheng the "Golden Record Award" for this work, which was later included in the 20th century Chinese classics.

　　Praising the motherland and people and eulogizing the times and life are the themes of Qin Yongcheng’s life creation. It is precisely because of Qin Yongcheng’s deep patriotism, deep thoughts and feelings for the broad masses of the people, including oil workers, rich musical language based on Chinese excellent musical culture, and continuous absorption of rich nutrition and creative sources in the long-term in-depth social life that he created such immortal masterpieces represented by "I Contribute Oil to the Motherland", which are full of positive energy and the main theme of the times, and have high artistic value and appeal to both refined and popular tastes.

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

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

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

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

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

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

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

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

Ten questions and answers about stem cells

01

What are stem cells?

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

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

02

What are the classifications of stem cells?

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

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

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

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

03

What is stem cell therapy?

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

04

What is the difference between autologous and allogeneic stem cells?

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

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

05

How can stem cells be used to treat diseases?

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

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

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

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

06

Is stem cell therapy risky?

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

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

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

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

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

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

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

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

07

What diseases can stem cell therapy treat?

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

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

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

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

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

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

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

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

08

What is the effect of stem cell therapy?

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

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

09

Is there an age limit for stem cell transfusion?

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

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

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

10

What are the taboo populations of stem cells?

Patients with advanced malignant brain tumors, especially brain tumors;

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

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

Patients with dysfunction of coagulation mechanism;

Patients with severe local infection;

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

People with high allergic constitution or severe allergic history;

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

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

Write it at the end

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

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

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

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

　　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.

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

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

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

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

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

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

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

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

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

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

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

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

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

　　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.
