Recently, I have seen some cases of technology introduction, talent training and industrial construction. I have always been very interested in the history of China’s industrial development. I have also bought some books and materials to read. I will continue to share some things today.

The national government in the Republic of China was undoubtedly a failure on the whole,

On the territory, it lost Outer Mongolia, which is more than 1 million square kilometers,

In terms of sovereignty, although it won the victory of the war of resistance against Japan, there are Soviet, American and British troops stationed on Chinese territory, and it is unable to drive these troops away,

In terms of national reunification, local forces in Tibet, Xinjiang, Yan Xishan in Shanxi, Ma warlords in the northwest, bandits and other places are like a country within a state, and cannot be effectively governed,

In terms of industrialization, it is impossible to build a tank, develop and mass produce heavy artillery, mass produce cars, and self-developed and mass produce aircraft. The fertilizers and pesticides needed for agriculture cannot be self-sufficient, and even a watch cannot be made.

In terms of national governance, every time floods, droughts and poor harvests occur, millions of people will die, which is like a tragic war.

As a short-lived regime, it naturally has its reason for failure.

Today we are talking about some cases of technology introduction by the national government. I think there are still some inspirations for us today. Some of these projects have been successful and some have failed, but the common point is that they have cultivated a group of excellent elite talents, which is of great help to the development of made in China.

Let’s talk about the aviation industry first,

The development plan of cxp-1001 fighter jet in 1940s

I also said a point before, and it is still the point now, that is, the most valuable legacy left by the old China to the new China is the cultivation of a group of elite talents, who mainly graduated from Tsinghua, Peking University, Central University, Jiaotong University, etc., and then were sent to Europe and the United States to study, work and study. Among them, the most famous is of course the two bombs and one star. Among the 23 two bombs and one star, only two did not study abroad, and the other two went to study in the Soviet Union. The other 19 graduated from Harvard, Yale, Purdue, Michigan, California Institute of technology, Berlin University, imperial Institute of technology, Carnegie Mellon University, University of Paris and so on.

But in fact, it’s far more than that. Take the aviation industry as an example. Where did the first generation of aircraft designers in New China come from,

In 1944, the national government issued an order to the aviation industry bureau to establish a jet research group,

The development group is divided into: engine development group, fuselage and engine layout development group, high-speed wing development group, landing gear development group and system development group. Based on a very blurred he-178 photo, the exploration of China’s early jet development began.

The national government publicly recruited and selected dozens of interns who stayed in the United States at public expense, and sent them to MacDonald aircraft company in St. Louis, the United States. Among them, they practiced jet fighter design, that is, Lu Xiaopeng, Yu Guangyu, Zhang Guilian, Gao Yongshou and others in the fighter design team. Lu Xiaopeng was the father of the strong 5 behind, and Yu Guangyu was later the chief designer of China’s first turbofan engine turbofan-5

At the same time as the fighter design group, the bomber design group, propeller group and plastic products group also went abroad for training. Xu Shunshou, who is well-known, was in the plastic products group at that time. Later, Xu Shunshou presided over the establishment of the first aircraft design office in New China in Shenfei and served as the director.

Xu Shunshou graduated from the Department of machinery of Tsinghua University in 1937, majoring in aviation. During his stay in the United States, he received FD-1 and Fd-2 design training. After returning home, he went to Nanchang Aircraft Manufacturing Plant and participated in the overall design and performance calculation of the zhongyun-2 and zhongyun-3 transport aircraft. He was mainly responsible for engine selection and aircraft shape alignment, and accumulated rich experience.

During the period of leading aircraft design in New China, Xu Shunshou collected a large amount of aviation information, especially the Design Memorandum when he designed the “zhongyun-3” in Nanchang in 1948. These books were brought from the south to the north, from Shenyang to Beijing, and then to Shenyang. He was never willing to lose them. Later, it also played a very important role in the design of j-teach 1 in the design room.

Xu Shunshou can be said to be the founder of China’s aviation industry. In any information about the development history of China’s aviation industry, the name of Xu Shunshou will be mentioned. The first self-developed jet aircraft in China, jianjiaoyi, was presided over by Xu Shunshou, who was the director of the aircraft design office.



The picture above is a group photo with Jian Jiao. From left to right, Lu Xiaopeng, ye Zhengda, Xu Shunshou, Wang Huiqing, Cheng Ziping, Gu Songfen, Wang Zixing.

The aircraft design room led by Xu Shunshou has cultivated many well-known aircraft designers in China. Among them, Xu Shunshou, Huang Zhiqian and Lu Xiaopeng had aircraft design experience before liberation, and the young people in the design room,

Cheng now and then became the deputy chief designer of Yun 10, Chen Yijian became the chief designer of Feibao, Gu xuanfen became the chief designer of J-8 II, and Tu Jida presided over the design of J-5 A and J-7 improved aircraft.

Not only Xu Shunshou, but also Lu Xiaopeng and others came to the United States to train elites.

In 1944, it was still in the period of Anti Japanese war. In late November, these trainees to the United States entered India from this “Hump route”. After arriving in Calcutta, India, take the train to the port of Mumbai, and then take the 10000 ton ocean transport ship “general” of the U.S. Navy to Los Angeles. At that time, there were some merchant ships in Mumbai port, but they did not dare to take these ships, nor did they dare to take the North Pacific route. Although this route was much closer, it was threatened by Japanese submarines at any time. As a result, they had to bypass the Indian Ocean, the South Pacific, and reach the United States through New Zealand.

In January 1945, they finally arrived in Los Angeles, a port city on the west coast of the United States.

Located in Missouri, the United States, St. Louis is an important industrial city and land and water transportation hub on the Mississippi River. The headquarters of McDonald aircraft company is located here.

James Smith MacDonald, the founder of this company, graduated from Princeton University, received a master of Science Degree in aeronautical engineering from Massachusetts Institute of technology, and worked as a pilot during the first World War. In 1939, MacDonald founded the MacDonald aircraft company. At first, it was limited to the design of bombers. In 1944, the U.S. Navy decided to order a full jet powered carrier aircraft, and McDonald aircraft company won the contract, resulting in the FH-1 “ghost” carrier aircraft. It was also from the FH-1 aircraft that McDonald aircraft company developed rapidly and expanded rapidly, and merged Douglas company in 1967, becoming one of the world’s largest aviation manufacturing companies.

When the Chinese engineers arrived at MacDonald, the flight test of FH-1 prototype FD-1 was being carried out here. But not long after, FD-1 crashed during a test flight, and then began the design of Fd-2.

About his study experience in the United States, Cheng Baoxuan, who studied in the United States and Britain with Lu Xiaopeng, later recalled in his book “jet fighter design team trained by the Kuomintang government in the United States and Britain”:

For the first nine months in St. Louis, the design team lived in the student dormitory of the University of Washington.

In addition to the internal training plan, the company also arranged two courses for the design team members at the University of Washington in the evening, namely, design drawing and strength calculation, mainly to be familiar with the company’s standards, specifications and practices.

Factory entry education is through visiting the factory and watching a complete set of audio-visual education films, including design, process preparation and manufacturing process, fighter flight test and combat films.

Then start the production labor practice for about 3 months, with two people in a group, taking turns to the main workshops and technology departments. During the production internship, it is treated as an apprentice, and the hourly salary is US $0.66.

Directly participate in the technical work of production labor and technology department during production practice. At that time, McDonald’s production tasks included: mass production of the tail wings, engine covers and other components of DC-3 transport aircraft (about 10 such components required by aircraft every day), small batch production of FH-1 shipborne fighter jets, development of small helicopters and missiles, etc.

After the production practice, it is the design practice. The design department should have an oral examination and conversation to understand each person’s education, experience and working ability, and arrange the internship position in the design department with reference to the performance in the production labor practice.

At this time, the salary starts from $0.77 per hour, and is assessed every three months, with salary increases as appropriate.

Therefore, everyone’s salary was different later. At that time, McDonald’s product design department was open to Chinese internship team members, including the development and design of Fd-2 machine and the modification and finalization design of FD-1 machine.

18 people from the Chinese design team went to the design rooms of these two models respectively. Most of them participated in structural design, and a few participated in aerodynamic calculation, strength calculation, mold line drawing and other work.

Lu Xiaopeng was assigned to participate in the structural design of Fd-2. Here, he felt the charm of aircraft design.

“Wheat plant design from scratch”, as Lu Xiaopeng said in his poem, Lu Xiaopeng did learn from scratch, which laid the foundation for him to comprehensively preside over the design work after he returned home.

During this time in the United States, there was one thing that made Lu Xiaopeng unacceptable.

The offices of the aircraft design department are composed of suites, and Chinese people are arranged in the outer rooms of each office. Whenever we encounter major technical problems and design changes, the door inside is closed. For such discrimination, everyone strongly felt humiliation and anger, but they were unable to fight back and had to swallow it.

Later, MacDonald company demanded more money from the Chinese national government through the U.S. government. Until the national government could not afford it, the United States interrupted its internship contract with China on the pretext that Fd-2 carrier based fighter was a new type of aircraft of the U.S. Navy and had confidentiality problems. Cheng Baoji recorded in his book:

The contract for training designers in McDonnell aircraft company lasts for one year, and the training fee is $1200 per person per year, which was extended for one year in 1946. However, later, the contract between China and the United States on the cooperative development of fighter jets was not negotiated because McDonnell aircraft company charged too much – it needed 40 or 50 million dollars, and the training plan was unsatisfactory, and the design team personnel could not be trained in a complete set.

After that, McDonald’s company used the trainers as labor force – after a year of training, the company had already rated most people as senior engineers, but at this time, it let them take the task of modifying drawings done by ordinary cartographers. Therefore, after repeated discussion, the design team decided to quit the company and complete the courses (one semester) at the Graduate School of the University of Washington, including elasticity, photoelasticity, structural strength calculation and industrial management.

After training in the United States, Xu Shunshou returned to China, but the national government did not give up its efforts to introduce technology.

In 1946, the national government signed a contract with Gloster aircraft company to jointly develop fighter jets.

This company is the first company of the allies in World War II to produce fighter jets, which is only a little slower than Germany. The meteor fighter, which was mass produced by this company in 1944, is the first fighter jet in service by the allies. This aircraft later participated in the Korean War and was also shot down by our army. Gloucester became part of British Aerospace Corporation (BAC) in the 1970s. The company is the largest aerospace enterprise and missile enterprise in Britain. Typhoon, the main fighter in active service of the British air force, was developed and manufactured by British Aerospace Corporation in conjunction with airlines in France, Germany and Spain. Of course, BAC also participated in the manufacturing of Airbus’ civil airliners.

In November, 1946, the national government asked Gloucester to prepare a single engine fighter program using the “black goose” engine, and jointly designed it with Chinese staff to train Chinese aircraft designers. At this time, Gloucester was applying to the British Aviation Department for approval of the manufacture of e.1/44 aircraft, and the e.1/44 plan was also provided to Chinese personnel for reference. The e.1/44 plan was also known as cxp-102 at that time. Subsequently, China and the UK formally signed a contract to jointly design and develop fighter jets. The design is carried out in Gloucester, and the process preparation and trial production are undertaken by the cooperative factory. The British Gloucester aircraft company agreed to provide a teaching and internship environment for Chinese personnel and cooperate in the development of a fighter jet, which was named cxp-1001.

At first, the British did not agree with the technical ability of Chinese engineers, and planned that the aircraft design would be completed by British engineers, but Chinese technicians believed that only their own design could have a real experience. With the Chinese side’s efforts, Gloucester finally decided that the design scheme of cxp-1001 would be selected by bidding. Finally, the general design scheme of cxp-1001 fighter jet of Chinese engineer Lu Xiaopeng was adopted. Lu Xiaopeng graduated from the Department of Aeronautical Engineering of Central University in 1941 and worked in the aircraft factory behind the Anti Japanese war for three years. In 1944, he was sent to MacDonald company of the United States to participate in the design of carrier based fighter jet, which gave him training.

The final design scheme adopted by Lu Xiaopeng is: a single seater light fighter, a Luo Luo’s “black goose” engine, with a thrust of 2200kg, a length of 12.8 meters, a wingspan of 11.65 meters, a maximum take-off weight of 6100 kg, a maximum speed of 1058 km / h, a maximum ceiling of 12056 meters, a sea-level climb rate of 30.5 meters / s, a maximum range of 1852 kilometers, equipped with four 20 mm machine guns, two of which can be replaced by 30 mm machine guns, Two auxiliary tanks that can be dropped can be carried under the wing, and conformal tanks can also be installed in the belly of the fuselage. The design plan was finally adopted, which proved Lu Xiaopeng’s excellent level at that time. However, the leader of the national government at that time suddenly adjusted Lu Xiaopeng’s post from the overall design to the tail wing, which hit Lu Xiaopeng badly, Later, he also wrote a poem to recall this matter: “recalling the past, Ge factory learned design, and the eagle plan was very ambitious. After thinking hard for months, Fang Qing and Britain proposed that it would be feasible. Ordering the handover of power and painting the tail wing would make the brain painful and the spirit difficult to calm. The reactionary scholars are ugly and hateful, and only knowledge can be returned to the people.”

Huang Zhiqian, who was in charge of the structural design of the rear fuselage of the cxp-1001 fighter jet, graduated from the Department of machinery of Shanghai Jiaotong University in 1938. During the Anti Japanese War, he was engaged in the repair of hawk 3, IL 15, IL 16 and other Chinese Air Force fighters in the rear. In October 1943, Huang Zhiqian was sent to the United States Convair aircraft manufacturing company as an employee to participate in the design of B-24 bombers Manufacturing and stress analysis of conville 240 twin engine transport aircraft – “air Palace”. In August 1945, after the victory of the Anti Japanese War, Huang Zhiqian was assigned to the Institute of Aeronautical Research at the University of Michigan to study mechanics. Later, because of the cxp-1001 project, he was transferred to Britain to be responsible for the structural design of the rear fuselage of this type of fighter jet. Of course, the Nationalist government, which was busy fighting the civil war, was defeated like a mountain, and the plan for this type of fighter plane, which had already put a small number of parts into production, was ruined. The contract was suspended. After Taiwan, the Kuomintang also tried to continue this plan independently, but failed, and the plan was completely stopped in 1953.

However, the first jet fighter in Chinese history has trained a group of talents. Although the British side is not willing to transfer technology completely and the core technical secrets are kept secret from the Chinese people, Chinese engineers still have access to some drawings and materials of British meteor and e.1/44 jet aircraft through various channels and study them carefully.

Lu Xiaopeng, who was in charge of the overall design of cxp-1001, later became the chief designer of qiang5, a famous machine of China,

Huang Zhiqian later became the first chief designer of the J-8.

Yu Guangyu later became the chief designer of the first turbofan engine turbofan-5 in China.

Gao Yongshou, after returning to China, became the chief craftsman of the first aircraft made in New China at Nanchang aircraft factory.

Zhang Guilian, who later became a professor of Beihang, directed the development of too many types of aircraft.

Of course, as mentioned above, before arriving in the UK, Lu Xiaopeng, Huang Zhiqian, Yu Guangyu, Gao Yongshou and Zhang Guilian all had experience working in American aircraft manufacturers. Among them, Huang Zhiqian was in conville company, while the other four were MacDonald company. In addition, Xu Shunshou did not go to the UK and returned home after studying in the United States.

After the aviation industry, let’s talk about the steel industry.

Development of steel technology in New China — from Germany to the Soviet Union

Because we are a backward country in industrialization, in fact, since modern times, China’s industrial technology can basically find foreign technology sources. The following figure is famous in the history of steel development in China. This picture shows the group photos of six steel technology experts when they studied in Germany in the 1930s. The first on the left in the front row is Li Songtang, the fourth on the left is shaoxianghua, the fourth on the left in the second row is the seal of the king, the first on the right is Jin Shuliang, the second on the left in the back row is Yang Shutang, and the second on the right in the back row is Mao Helian who wears glasses.

Three of the six graduated from Beiyang University in Tianjin, and the other three graduated from Zhejiang University, Peking University and Tongji University. In order to prepare for the construction of the Central Iron and steel plant, the national government sent them to various iron and steel plants subordinate to Krupp in Germany for internship. Jin Shuliang studied at the Rhine village iron and steel plant under Krupp, which was a world-class iron plant. At that time, the daily output was as high as 7000 tons, accounting for one tenth of Germany’s iron output. During this period, Jin Shuliang wrote a detailed investigation report.

With the outbreak of the war of resistance against Japan, the Central Iron and steel plant plan ran aground. After returning home, the six people were given different tasks during the war of resistance against Japan, and underwent training in the national industry in the rear area of the war of resistance against Japan,

Among them, Jin Shuliang first worked in the steel plant relocation Committee of the national government, responsible for the demolition of Hanyang Steel Plant and Liuhegou steel plant to Chongqing Dadukou, and later served as the director of Weiyuan iron plant.

Wang Zhixi went to Kunming to participate in the preparation for the construction of Yunnan iron and steel plant;

Mao Henian taught at Chongqing University;

Shaoxianghua first taught at Wuhan University and founded the Department of metallurgy. Later, a small modern iron and steel plant based on modern scientific theory was established in Qijiang, Chongqing, the first new open hearth furnace in China was designed, and the first batch of iron and steel practical teams were trained for China… People like zhangchunming, zhangxingqian, zhangshouhua, etc. later, they were the backbone of iron and steel enterprises, and they were more prestigious experts in China.

After returning to China, Yang Shutang came to the 24th factory of the ordnance industry administration, which produces military steel. He successfully refined China’s first furnace of 75mm barrel steel and stainless steel, and also manufactured cold cast rollers for the first time. Then, Yang Shutang went to the Ziyu steel plant to lead people to develop a new steel-making method – “Ziyu steel-making method”. Li Songtang, who also came to Ziyu iron and steel plant, was responsible for the design, manufacture and installation of a new steel mill.

After the victory of the war of resistance against Japan in 1945, six people were sent to the northeast to take over Angang as the associate (deputy general manager, responsible for technical work), of which Jin Shuliang was the first associate. However, because the Kuomintang was busy fighting the civil war, Angang resumed production slowly.

After the liberation of Angang Steel in December 1948, six people were protected by the people’s Liberation Army. The mayor of Anshan City and the deputy director of the Public Security Bureau personally entertained them for dinner. The six people decided to stay and start Angang Steel to resume work. At this time, Angang Steel retained more than 100 Japanese technicians. Not only Japanese engineers did not believe in the technical level of Chinese engineers, but the workers also had doubts about the technical ability of Chinese engineers. Fortunately, under the leadership of our party, Angang Steel was determined to achieve technological autonomy. In the process of resuming production, engineers of the two countries had various disputes, and both preferred to adopt the Chinese scheme, and Chinese engineers also proved their ability with actual results.

Yang Shutang said in his memory, “the workers were very happy to see that the Chinese engineers had insight in technology and dared to adhere to their own opinions, and they became more and more intimate with me…” because the Chinese engineers could operate Angang independently, the ineffective Japanese technicians gradually returned home, and by the end of 1952, the Japanese technicians basically returned home.

As China decided to adopt Soviet technology to develop Anshan Iron and Steel Co., Ltd., a large number of Soviet experts and equipment came to Anshan Iron and Steel Co., Ltd., making the technical route completely shift to the Soviet technical route. Anshan Iron and Steel Co., Ltd. became a key project in the first five year plan.

Three of the six steel technology experts (Jin Shuliang, Wang Zhixi and shaoxianghua) were selected as members of the first batch of academic departments of the Chinese Academy of Sciences (later renamed academicians) in 1955. Later, Mao Helian was also selected in 1980, and a total of four academicians of the Chinese Academy of Sciences came out.

Next is the semiconductor industry.

Taiwan’s semiconductor industry chain can be said to be the most complete in the world. Its design ranks second in the world (in fact, the mainland should be the second in the world if Hisilicon is not crippled), its manufacturing ranks first in the world, and its sealing and testing ranks first in the world. It is mainly the upstream EDA software. The equipment and materials are not good, and it also depends on the United States and Japan. However, even for materials, Taiwan also has global wafer, the world’s top three world-class silicon wafer enterprises, which are in short supply, Its long-term contract has been scheduled to 2028, and even some customers want to sign until 2031.

Taiwan’s semiconductor program originated in the 1970s. The political cause was that Jiang Jingguo hoped to have a breakthrough science and technology project when he was engaged in the construction of the ten major projects, so he asked Fei Hua, Secretary General of the Executive Yuan, to take charge of this matter,

In October, 1973, he found his alumnus Fang Xianqi, director of the General Administration of telecommunications of Taiwan, and pan Wenyuan, an alumnus who served as a scientist and laboratory director at American Radio Corporation, to discuss. The three of them were alumni of Jiaotong University (Shanghai) in the Republic of China. Pan Wenyuan, who had worked in the United States for many years, proposed that Taiwan should develop the semiconductor industry based on his understanding of the latest scientific and technological revolution in the United States.

This aroused the interest of Fei Hua and Fang Xianqi, so he invited pan Wenyuan to Taiwan for a detailed discussion, so there was the famous “Taipei xiaoxinxin soymilk store” meeting that decided on the beginning of Taiwan’s semiconductor industry on February 7, 1974. There were seven participants. In addition to Fei Hua, Fang Xianqi and pan Wenyuan, there were also the Minister of transportation, the Minister of economy, the president of the Industrial Research Institute and the director of the Telecommunications Research Institute. Six of the seven were mainland Chinese, Five of them graduated from Shanghai Jiaotong University, and sunyunxuan, the Minister of economy who is in charge of Taiwan’s semiconductor program, is from Shandong. He graduated from the China Russia University of technology in Harbin. In the 1930s and 1940s, he was responsible for the construction of the power industry in all provinces in the national government, and was sent to the United States by the national government for training for two years. He is a technocrat.

At the meeting, it was discussed and decided that Taiwan should follow the direction of the semiconductor industry. At the same time, it was believed that Taiwan’s electronic watch industry had a considerable scale at that time, and the chips manufactured could be first used in electronic watches. Pan Wenyuan, who was familiar with American industry, believed that the technology introduction could be made at a cost of 10 million US dollars in four years. The meeting decided that Pan Wenyuan would be responsible for writing the plan, and sunyunxuan, Minister of economy, would be responsible for this matter, After invitation and evaluation to many companies in the United States, it was finally selected to introduce technology from RCA company in the United States, which has the most positive attitude.

In May 1976, Taiwan sent the first batch of personnel to the United States for training. At the travel meeting, former Minister of economy sunyunxuan asked these trainees to “only succeed, not fail”. A large number of meritorious figures in Taiwan’s semiconductor industry emerged from these young people who went to the United States for training, Including caoxingcheng (later the general manager and chairman of Lianhua electronics, and together with TSMC chairman Zhang Zhongmou, they are considered to be the two giants of Taiwan semiconductor OEM), Zeng Fancheng (successively served as the vice chairman of TSMC and the world’s advanced chairman), Yang Dingyuan (later the vice chairman of Huabang), and a young Taiwanese man named Cai Mingjie was also selected into the program to become one of the five people studying IC design, and later he became the chairman of MediaTek.

In the 1980s, through long-term contacts, Taiwan’s mainland technocrats finally successfully invited Zhang Zhongmou, a world-class semiconductor technology expert, to Taiwan as the president of the Industrial Research Institute, and later founded TSMC. However, it is interesting that when sun Yunxuan first officially invited Zhang Zhongmou to Taiwan, Zhang Zhongmou refused. He later said that the reason was “after talking, I found that they didn’t know much about the treatment of American Enterprise Executives”. In fact, Zhang Zhongmou was in his fifties when he came to Taiwan. He had been in Chinese Mainland and Hong Kong before the age of 18. He went to Harvard University in 1949 and worked in the United States after graduation. He stayed in the United States for more than 30 years. The first 50 years of his life had nothing to do with Taiwan.

In those years, there were indeed many senior talents in the group who went to Taiwan with the Kuomintang, and it took Taiwan 40 or 50 years to have its current position in the semiconductor industry. In recent years, the mainland’s investment in the semiconductor industry has gradually increased on a large scale, and the two sides are comparing the investment intensity. In recent years, the semiconductor industry has been booming, so Taiwan can also maintain a very high investment intensity and continue to maintain its leadership over the mainland.

When the semiconductor industry enters a downward low tide and the industry profits decline, it is the most unfavorable for Taiwan. At this time, it is the time for the mainland to catch up. Of course, the premise is that when the market profits decline, the wave of sustainable high-intensity capital investment + localization cannot be relaxed, and the capital investment of sea volume + market localization overwhelms the other side.

Today, let’s talk about the steel industry, aviation industry and semiconductor industry. In fact, there are many examples like this.

In the early fifties of the founding of the people’s Republic of China, China’s elite technical talents were mainly from Europe and the United States who studied and returned from work, while technology and equipment were mainly from the Soviet Union. This cooperation with advanced countries made China’s industrialization capacity in the fifties an era.

Today in 2022, why should China insist on opening up and globalization when the United States tries to decouple, because it is good for China’s national interests.

On July 17, Beijing time, Chinese long jumper Wang Jianan won the first men’s long jump world championship in Chinese history. He hugged foreign coach Randy after winning the championship Huntington is also the coach of Su Bingtian.

After Randy became Su Bingtian’s coach in 2017, Su Bingtian made great progress:

In February and March 2018, the indoor men’s 60m Asian record was refreshed twice, equalling the men’s 100m Asian record with 9.91 seconds in June of the same year, and then breaking the 100m Asian Games record at the Jakarta Asian Games in August.

In the 2021 Tokyo Olympic Games, Su Bingtian ran 9.83 seconds in the men’s 100 meter semi-finals, breaking the Asian record and creating Chinese track and field history.

Coach Randy is the coach of Powell, the world record holder of the long jump. The advanced training methods he brought have greatly improved the performance of Chinese track and field.

The history of industrialization since the founding of the people’s Republic of China has shown that if we want to successfully realize the great development of manufacturing and science and technology, we must give priority to ourselves and accept all rivers. Neither of them is indispensable.
