Xu I’s life is only for that "China star"

Open the vast book of our country’s aerospace industry, "Dongfanghong No. 1", as the first monument in the history of our country’s aerospace, has been expressed and paid tribute in different forms by countless literati and writers.

Here, we see the group portraits of Chinese astronauts who are self-reliant, understand the firm belief in serving the country through science in difficult times, and thus remember the names of a group of patriotic scientists such as Qian Xuesen, Ren Xinmin, Sun Jiadong, and Qi Fa Qi.

Don’t forget to dig wells. For any cause or any project, the role of the founder, paving stone and lookout is undoubtedly the most important, and it is also easy to be forgotten by future generations. They need to have extraordinary wisdom, firm belief and a strong heart. In the initial stage of the development of our country’s first artificial satellite, there were two people who were close and far away from us. Speaking of near, because the launch of Dongfanghong No. 1 was less than 50 years ago, and we have a lot of information to consult and learn; speaking of far, they have long since left us.

They are all the pioneers and founders of our country’s space technology – Zhao Jiuzhang and Qian Ji.

One day at the end of July, under the recollection of Mr. Hu Qizheng, an 84-year-old member of the overall team of the Dongfanghong-1 satellite, the passionate years that had passed with Zhao Jiuzhang and Qian Ji were once again awakened.

The birthplace of Chinese satellite development –

No.1 West Garden Playground

At the behest of Chairperson Mao, "We also want to develop artificial earth satellites," in 1959, after graduating from the electrical engineering department of Tsinghua University, Hu Qizheng, 24, was assigned to a "mysterious unit" – Group 581, which was responsible for formulating satellite plans and organizing and coordinating satellite and rocket sounding operations. At No. 1 Xiyuan Playground, he met Qian Ji, the head of the office of Group 581, for the first time.

At that time, Qian Ji was actually the person in charge of the overall satellite technology. The first time they met, Qian Ji, who had few words and deep eyes, expressed three meanings to Hu Qizheng: first, welcome, second, pay attention to confidentiality, and third, we are engaged in space exploration, and we will do things in the future. Hu Qizheng was very excited when he heard it, and from then on, he started his aerospace career, and Qian Ji was also regarded by him as the leader of his aerospace career.

No. 1, Xiyuan Playground, a courtyard borrowed by the Chinese Academy of Sciences from Zhongzhi Xiyuan organs around 1954. According to Wu Zhicheng, Secretary of the Party Committee of the Institute of Space Physics of the Chinese Academy of Sciences (then in charge of the management of the 581 scientific research program), it was overgrown with weeds and simple conditions, but it was the birthplace of our country’s space industry: the proposal for the establishment of a national satellite project in our country was drafted here; the idea of our country’s first satellite was brewed and born here; the pre-research of the satellite was launched here; the meteorological rocket detection test was started here…

There is a three-story gray brick building on the north-south side of the hospital, which is used as a research laboratory. Then dozens of bungalows were built one after another, including administrative office rooms, machining workshops, glass workshops, equipment warehouses, garages, etc. Early developers also converted a dry toilet in the northwest corner into an environmental simulation laboratory. To make vacuum instruments, they also built their own earth gas generator, which is used for blowing glass and sealing vacuum tubes.

At that time, following the scientific policy of diligence and frugality, everything was simple. The eight research groups working here were fully engaged in rocket sounding research and satellite pre-research preparations.

At the beginning of the formation of the 581 group, Zhao Jiuzhang, Qian Ji, Yang Jiachi and his party went to the Soviet Union to observe the satellites with great interest, but they only took a look at the appearance of the satellites from a distance, let alone cooperation and technical assistance. Without learning the ability of satellite development, it inspired the fighting spirit of scientists: If you don’t let it learn, we will do it ourselves! It is proud that our country has developed the satellite business completely by self-reliance from scratch.

After investigating the industrial base at home and abroad, combined with the economic conditions and scientific research conditions of our country at that time, scientists in our country suggested that "the current satellite launch is not commensurate with national strength, and the space technology research mission should be adjusted." The 581 group then made adjustments and focused its research on sounding rockets.

In 1960, Chairperson Mao Zedong visited a sounding rocket

From 1959 to 1965, the research entities led by Zhao Jiuzhang, Wei Yiqing, and Qian Ji worked actively, and worked closely with the Shanghai Electromechanical Design Institute led by Yang Nansheng and Wang Xiji. From 1960 to 1965, more than 20 T7 and T7A sounding rockets were launched and tested, and meteorological data below 60 kilometers were obtained. Ionospheric, biological and other projects were tested. These have laid a certain technical foundation for satellite development.

From 1960 to 1962, China’s aerospace industry was a "difficult and progressive three-year period". It was difficult because the people of the whole country were facing the same problem: not having enough to eat. The astronauts were no exception. Qian Ji and Hu Qizheng had to spare two catties of food for their comrades who ate a lot. Zhao Jiuzhang and Qian ****** puffy legs due to malnutrition.

More difficult than not having enough to eat and no clothes to wear is the resistance at work, no clue. I have never done a satellite, and no one has done a satellite. Qian Ji said, don’t be afraid, we will do it ourselves. He led everyone to look up the literature, bit by bit, from scratch.

After studying, they found that compared with the Soviet Union, the literature reference value of the United States is better. But everyone’s English level is very limited, what should I do? So Mr. Qin Xinling and the English-speaking technicians took the initiative to teach you professional English.

When it comes to learning English and reading literature, Qian Ji is a famous English expert. Although he has no overseas study experience, he loves to learn and is eager to read literature. He has a special habit of making his own reading cards while studying. In his lifetime, he made nearly 20,000 reading cards, forming a huge and precious database. In the era without computers, these cards were the greatest intellectual support. Hu Qizheng fondly recalled: "Qian Ji taught us how to read books and how to read literature."

Qian Ji at work

At No. 1 Xiyuan Playground, although the days were hard, everyone was very motivated. Every night, the leaders came to urge the young people to turn off the lights and go back to rest early. Qian Ji always encouraged everyone: There must be a goal in life, otherwise there is no meaning in living. Under the leadership of Zhao Jiuzhang and Qian Ji, everyone basically figured out the composition, function and key technologies of the satellite, and figured out the way of satellite development in our country. "Application as traction" has become the guiding ideology of satellite research and development in our country.

1965 –

Our country restarts satellite development plan

In October 1964, Zhao Jiuzhang and Qian Ji visited Base 20 (now Jiuquan Satellite Launch Center) at the invitation of the National Defense Science and Technology Commission. After this visit, one night in early November 1964, Qian Xuesen came to Zhao Jiuzhang’s office. When Qian Xuesen met, he asked, "What is the impression of going to the base?" Zhao Jiuzhang said, "The harvest is very large, and the missile development progress is so fast, which is really unexpected." Zhao Jiuzhang believes that in another four or five years, the launch vehicle of about 100 kilograms of satellites may be developed, and the satellite development is also certain to be completed. Now the key is that the satellite development must be approved by the state.

Zhao Jiuzhang urgently felt that he should write a report to the central government to express the necessity and possibility of developing satellites. In January 1965, Qian Xuesen wrote to Nie Rongzhen, arguing that the conditions were now in place to consider the satellite issue.

Previously, the developers of No. 1 in Xiyuan Playground have been renamed from Group 581 to the Second Department of Geophysics. They have formed a professional satellite development team, and Qian Ji, deputy director of the Second Department, is the general technical director of the satellite. Satellite development in our country has thus embarked on the road of professional development.

In order to submit the report to the central government as soon as possible, the Academy of Sciences instructed a general team composed of He Zhenghua, Pan Houren, and Hu Qizheng, directly led by Qian Ji, to write the "Ten-year plan for the development of our country’s satellite industry" and the "Proposal for the development of our country’s artificial satellite work". Two reports, the plan was finally submitted to the central government by the Chinese Academy of Sciences. In August 1965, Zhang Jinfu, then the secretary of the Chinese Academy of Sciences Party Group, reported at the 13th meeting of the Central Special Committee and received a reply: Pass, execute! Since then, the satellite development project has been officially established, and the Chinese Academy of Sciences has listed this as the No. 1 task in 1965, code-named "651".

From October 20 to November 30, 1965, the Science Hall of Beijing Friendship Hotel held our country’s first satellite demonstration. The meeting was chaired by Pei Lisheng, vice president of the Academy of Sciences, and there were more than 120 representatives. The experts fully discussed and reached consensus on many issues. The meeting lasted for 42 days.

The conference produced four documents on the overall plan, the main body plan, the vehicle plan, and the ground system plan for our country’s first satellite, and also prepared 27 special materials with a total of about 150,000 words. During the conference, Premier Zhou invited the delegates to the small auditorium of the Great Hall of the People to watch the performance of the party. This conference is very important in the history of aerospace in our country, and it clarified the idea of "a game of chess across the country" to build satellites.

During the meeting, Premier Zhou took the initiative to ask Qian Ji’s name when listening to the report, and said with a smile: "Your surname is Qian too! It seems that satellites are not short of money."

The Prime Minister’s words were a pun. There was Qian Xuesen in missiles, Qian Xuesen in atomic bombs, and Qian Ji in satellites now, so there was really no shortage of money. Another layer of meaning was that satellites cost a lot of money, just like atomic bombs and missiles. The Prime Minister asked Qian Ji how much it would cost, but Qian Ji did not answer, because there was no calculation in the preparation of satellite plans and demonstrations. The state wants to approve the satellite project, I don’t know how much it will cost, how to make a budget, and what to do with the approval procedures? This made the scientist surnamed Qian start to worry about money.

Hu Qizheng is still deeply impressed by this experience. Because of the work relationship, he and his colleagues have been fortunate to work with great scientists such as Zhao Jiuzhang, Yang Jiachi, Chen Fangyun, and Qian Ji. The academic aura and peace in life of great scientists, the indifference to fame and fortune, and the democratic and practical work style of great scientists have allowed the young Hu Qizheng to witness the "master style". He confessed that he was fortunate to benefit for a lifetime.

"Cultural Revolution" –

Satellite development is moving forward amidst difficulties

Scientists really wanted to put the first man-made satellite in the sky before the National Day in 1969. It was a great honor to release the first satellite 20 years after the founding of New China. According to everyone’s preparations at that time, there was no problem at all, but it was not realized.

Because the "Cultural Revolution" is here.

During the day and night, the barbaric and frenzied criticism and struggle ravaged the scientific researchers physically and mentally. Zhang Jinfu was seized from power, the party group of the Chinese Academy of Sciences collapsed, the grass-roots party organizations were paralyzed, and No. 1 Xiyuan Playground became the hardest hit area. Some were injured, some were killed in combat. Zhao Jiuzhang was persecuted to death in October 1968. In such a chaotic situation, comrades who can work are still working.

After Zhao Jiuzhang passed away, Qian Ji was also affected. After "stepping aside", he worked like an ordinary technician, but remained silent as always. Seeing the persecution of scientists who were once respected by people, everyone felt deeply helpless. The development of satellites is advancing slowly in difficult situations.

Dongfanghong No.1 engine hoisting test

At the end of 1967, the country began to plan the establishment of a space technology research institute, and the office location was also moved from Xiyuan Playground No. 1 and Zhongguancun to Baishiqiao. Sun Jiadong was appointed as the general manager of Dongfanghong No. 1 when he was in danger. He brought more than 10 business backbones to integrate the engineering experience of missile development into satellite engineering. In that stormy era, everyone defied all difficulties and pushed the development of Dongfanghong No. 1 satellite forward steadily.

On April 24, 1970, the Dongfanghong-1 satellite spewed out, and the world was excited. The two founders who actively promoted the development of the satellite: Zhao Jiuzhang and Qian Ji, one was already wronged and could not witness this moment with his own eyes; the other could only look up silently from the open space of Baishi Bridge in Beijing. In the face of cheers and applause, without them, in that era, they would have been low to the dust.

People who like to watch the Dongfanghong-1 satellite fly overhead

Fast forward to 1999. On September 18 of this year, on the occasion of celebrating the 50th anniversary of the founding of the People’s Republic of China, the Party Central Committee, the State Council, and the Central Military Commission decided to commend 23 scientific and technological experts who had made outstanding contributions to the development of "two bombs and one star" that year, and awarded Yu Min, Wang Daheng, Wang Xiji, Zhu Guangya, Sun Jiadong, Ren Xinmin, Wu Ziliang, Chen Fangyun, Chen Nengkuan, Yang Jiachi, Zhou Guangzhao, Qian Xuesen, Tu Shoue, Huang Weilu, Cheng Kaijia, and Peng Huanwu the "Two Bombs and One Star Merit Medal", and posthumously awarded Wang Fanchang, Deng Jiaxian, Zhao Jiuzhang, Yao Tongbin, Qian Ji, Qian Sanqiang, and Guo Yonghuai the "Two Bombs and One Star Merit Medal" (the above rankings are based on surname strokes Order).

More than 60 years have passed, and few people walking in Xiyuan Playground A-1 now know that so many big scientists have come out from here to brew our country’s satellite research and development business. That period of time has become history. But our country’s satellite business has developed from "Dongfanghong No. 1" to bright stars, adding more light to the rising China.

Controversy! Jeff, the new captain of Guangdong Men’s Basketball Team, may make a new decision, and the reason is revealed!

The emergence of Jeff, the new captain of Guangdong Men’s Basketball Team, has caused some controversy. Some fans have doubts about whether he can be the captain. However, the management is firm about Jeff’s choice, and thinks that his leadership and team consciousness are enough to lead the team to success. Jeff himself also said that he would try harder and go all out to respond to the fans’ expectations. Jeff’s appointment as the new captain of Guangdong Men’s Basketball Team has undoubtedly aroused various voices among fans. The management of Guangdong Men’s Basketball Team firmly believes that Jeff is the best candidate, and they believe that Jeff’s leadership temperament and team consciousness are the key to the team’s success. On the court, he showed extraordinary dominance and leadership, as well as the ability to play a stabilizer role in the team.

In addition, he is always the leader of his teammates off the court and has established a close cooperative relationship for the team. The management believes that Jeff as the new captain is the best choice for Guangdong men’s basketball team to win the championship in the future. However, it is undeniable that some fans’ controversy about Jeff becoming the captain is also reasonable. Being a captain is not only about the performance of basketball skills, but also includes leadership, emotional management and tactical decision-making. For a top team like Guangdong Men’s Basketball Team, the captain’s responsibility and pressure are enormous. Some fans are worried about whether Jeff can keep calm at critical moments and how to adjust tactics and motivate players in adversity.

These concerns are reasonable to some extent, because the captain’s role is not only to celebrate the victory, but also to lead the team unswervingly when it is difficult. Jeff himself is full of determination and confidence to become the new captain. In an interview, he frankly knew that the fans had high expectations of him, but he also said that he would respond to these expectations with greater efforts and all-out efforts. He believes that becoming a captain is a new challenge and a great honor in his career. He said that he will work closely with the coaching staff, learn and improve his leadership ability, and lead the team towards the goal of championship. As the new captain of Guangdong Men’s Basketball Team, Jeff will face a series of advantages and challenges.

First of all, as a captain, he will have more voice and influence, be able to better communicate with coaches and management, and strive for better resources and support for the team. His leading position in the team will also make his teammates trust him more and be more willing to obey his command. However, the duties of the captain are also accompanied by great pressure and challenges. He needs to stand up when the team encounters difficulties, boost morale and lead the team out of the trough together. At the same time, he also needs to constantly improve his level on the court and become a model and example for the team. Looking ahead, the importance of Jeff as captain is self-evident. He will show his skills and leadership on the court, and he will also face the judgment of all parties.

However, no matter what challenges he faces, Xu Jie said that he would go all out and do his best to bring more honor and glory to the Guangdong men’s basketball team. Only time will tell whether Jeff can be the captain, but he has become an important symbol for fans and Guangdong men’s basketball team, symbolizing a new chapter and a new beginning. Let’s look forward to more brilliant achievements of Guangdong Men’s Basketball Team under his leadership.

Arsenal have no title for 19 years! In 248 days, it topped the list but set an embarrassing record. The third time, it suffered a big reversal.

On May 21st, Beijing time, Arsenal lost 0-1 to Nottingham Forest, sending Manchester City to win the championship ahead of time, but they missed the Premier League championship for 19 consecutive years! The hope I just saw was dashed again.

When was the last time Arsenal won the Premier League title? 2003-04 season, 19 years ago! At that time, they won the championship unbeaten under the leadership of Wenger, which was the only time in the history of the Premier League. However, it was the culmination of glory and the beginning of decline.

Since then, Arsenal has never been involved in the Premier League trophy, and it has degenerated into fighting for four. Until 2018, Wenger regretted leaving, and so on. And his successor, emeri, also failed to recover.

However, this season, under the training of Artta, the gunman suddenly rose and led all the way. At the beginning of April this year, he once led the second Manchester City by as much as 8 points, and it is very promising to break the spell!

However, at the critical moment, they habitually dropped the chain. After a series of three consecutive draws, they lost to the Blue Moon 1-4 in the battle of Tianwangshan, handing over the top throne that had been held for 248 days.

In the final sprint, Arsenal lost to Brighton and Nottingham Forest one after another, leaving Manchester City at home! There are only 2 wins in the last 8 rounds, which is really a complete collapse.

You know, after 248 days at the top of the list, but ultimately failed to win the championship, Arsenal created an extremely embarrassing Premier League historical record! The previous holder was Newcastle, which held the top spot for 212 days in 1995-96, but was reversed by Manchester United.

In the 2002-03 season, Arsenal stayed at the top of the list for 189 days, and in the 2007-08 season, they stayed for 156 days, all of which were turned over, which can be said to be an "old tradition".

Telegraph: The owner of West Ham has no intention of selling the team, and the top management of the team trusts moyers.

Live on March 11th According to the Daily Telegraph, the owner of West Ham has no intention of selling the team, and the top management of the team now trusts moyers.

It is reported that David Sullivan, the owner of West Ham, said that he has no intention of selling the team, which means that moyers’s job is safe at present. At present, West Ham still has 13 games to play in the Premier League, and the fans of the team are still full of hope for West Ham. Although West Ham is currently only 16th in the Premier League standings, they are confident that they can change the current situation.

For a long time, it has been thought that Czech billionaire Clay Tynsky, who owns 27% of the club, will launch the acquisition of West Ham, but if Clay Tynsky wants to launch a comprehensive acquisition, he must obtain the consent of David Sullivan (holding 38.8%) and the family of the deceased co-owner David Gold (holding 25.1%) before starting the acquisition process. Logically speaking, Clay Tynsky is unlikely to make an offer at present, because the current situation of West Ham in the Premier League is still unclear, and if relegated to the Championship, it will obviously affect the value of the club. In addition, even if it is sold, David Sullivan will not sell West Ham at a low price. According to sources, David Sullivan has no intention of selling West Ham, and he has not even considered doing so.

West Ham are currently playing in the UEFA, and they are facing teams with average strength in this level of European war, which is completely different from their opponents in the Premier League. In last week’s UEFA competition, they beat AEK Larnaca 2-0 away, which was their ninth consecutive victory in this competition. If West Ham can win this tournament, it will be the team’s first European trophy since 1965, and more importantly, it will also ensure their qualification for the Europa League next season. However, West Ham’s performance in the Premier League is somewhat disappointing. They have not won in the past eleven away games. Although the fans shouted moyers’s dismissal after West Ham’s 4-0 defeat to Brighton, as far as the current situation is concerned, moyers’s position is still very stable. However, according to relevant media reports, West Ham is currently considering short-term and long-term substitutes to replace moyers, and Nuno Espirito Santo, Benitez and Dych are all considered as potential choices.

Moyers has one year left on his contract with West Ham, and they may end their cooperation with moyers when his contract expires. Last summer, West Ham invested 160 million pounds in the transfer market, which is the third highest transfer expenditure in the Premier League. In addition, West Ham signed Danny Ince in the winter window that year. People hope that West Ham can challenge the qualification of the Champions League instead of struggling to avoid relegation. Moyers’s team has been plagued by injuries this season, and his tactics have been questioned by people. However, the team’s offensive line scored only 23 goals in 25 games, which really made him feel a little overwhelmed. However, West Ham hopes that moyers’s experience will help the team overcome the difficulties and try to win a trophy.

Sassuolo executives: Will Fratesi join Rome? We will try our best to meet the requirements of the players.

Live broadcast: On March 11th, when interviewed by the reporter of Corriere dello Sport, Carnevali, CEO of Sassuolo, talked about the rumors of Fratesi and Rome.

Carnevali said: "We should have a correct attitude. Sassuolo should be regarded as a springboard for players to join the giants. Fratesi has all the strength to make a leap forward, and now we must try to reach an agreement that can satisfy our three parties. We will find the best solution. In addition to economic factors, we will also try our best to meet the requirements of the players themselves. "

"We have been investigating Bovi and volpato in Rome. Before that, Rome sent many high-potential teenagers to us for training, giving us a high split, such as Politano and Lorenzo pellegrini."

According to the whole market, besides Roma, Juventus are also paying attention to Fratesi.
