The main content of Motherland, I'm Back at Last is:

Qian Xuesen is an outstanding scientist in China. He studied in the United States in his early years, obtained a doctorate with excellent academic performance, and became an expert in aviation engineering and aerodynamics. He made great progress in rocket research and was hired as a tenured professor by Massachusetts Institute of Technology. In America, he has money, status and reputation.

However, as soon as he heard the news of the founding of the People's Republic of China, Qian Xuesen immediately decided to return to work. He said, "I am from China. I can give up everything here, but I can't give up my motherland. I should return to the motherland as soon as possible and contribute all my strength to building a new China. "

in September p>195, Qian Xuesen resigned from his job, went through the formalities for returning to China, bought a plane ticket for returning to China, and handed over his luggage to American airlines. However, at this moment, he received a notice from the US Immigration Service: No return to China! He had to refund his plane ticket. The US Customs opened his luggage for inspection, insisting that it contained important secrets and that Qian Xuesen was a spy.

In fact, his luggage only contains textbooks and notebooks that he is going to take back to China. A few days later, Qian Xuesen was suddenly arrested, locked up in an island detention center and tortured endlessly. Every night, the guards turn on the lights every 1 minutes, so that he can't rest at all. In half a month, he lost nearly 15 kilograms.

The persecution of Qian Xuesen by American authorities has aroused public indignation in American scientific circles. Many American friends came forward to rescue Qian Xuesen. They raised $15, to bail Qian Xuesen out of the detention center. However, the FBI still does not relax its persecution of him. His movements were restricted, his letters were checked and his phone calls were monitored. However, Qian Xuesen did not give in. He kept asking: I want to leave the United States and go back to my motherland.

in this way, he persisted in the struggle for five years. His struggle has won the support of people who uphold justice all over the world, and has received great care from the government of China and the people of China. Premier Zhou Enlai was very concerned about Qian Xuesen, and asked him personally about his situation, and instructed China delegates attending the ambassadorial meeting between China and the United States to raise the issue of Dr. Qian Xuesen's return to China during the meeting. In 1955, the American government was forced to agree to Qian Xuesen's return to China. On September 17th of the same year, Qian Xuesen boarded the ship returning to China. On October 8, he returned to the embrace of the motherland with tears of happiness.

The day after Qian Xuesen arrived in Beijing, he took his whole family to Tiananmen Square. Looking at the magnificent Tiananmen Gate, he said excitedly, "I believe I can definitely return to my motherland, and now I am finally back!" "

Extended information

Before going abroad

Qian Xuesen was born in Shanghai in 1911, and his ancestral home was Lin 'an, Hangzhou, Zhejiang Province. In September 1923, he entered the middle school affiliated to Beijing Normal University. ?

in p>1929, he was admitted to the Department of Railway Engineering of Shanghai School of Mechanical Engineering of the Ministry of Railways, and graduated from national chiao tung university (now Shanghai Jiaotong University and Xi 'an Jiaotong University) in 1934. In June, he was admitted to the seventh Geng Prize of Tsinghua University to study in the United States.

in September p>1935, he entered the aviation department of the Massachusetts Institute of Technology in the United States. In September 1936, he obtained a master's degree in aviation engineering from the Massachusetts Institute of Technology, and then transferred to the aviation department of the California Institute of Technology to study. He became a student of the world-famous great scientist Theodore von Kármán, and soon became the most important student of von Carmen.

He received a master's degree in aviation engineering and a doctorate in aviation and mathematics. From July 1938 to August 1955, Qian Xuesen studied aerodynamics, solid mechanics, rockets, missiles and other fields in the United States, and completed the research topic of high-speed aerodynamics and established the "Carmen-Qian Xuesen" formula with his mentor. At the age of 28, he became a world-renowned aerodynamicist. ?

in p>1939, he received a doctorate in aviation and mathematics from California Institute of Technology. In 1943, he served as an assistant professor at California Institute of Technology. In 1945, he served as an associate professor at California Institute of Technology. In 1947, he became a professor at MIT.

in p>1947, she married Jiang Ying in Shanghai. In 1949, he served as director and professor of the Jet Propulsion Center of California Institute of Technology. In 1953, Qian Xuesen formally put forward the concept of physical mechanics, and advocated that the macroscopic mechanical properties of matter should be determined from the microscopic laws, which opened up a new field of high temperature and high pressure.

In p>1954, the English version of Engineering Cybernetics was published, and the Russian version, German version and Chinese version were published in 1956, 1957 and 1958 respectively. In 1958, he served as the director of the Department of Modern Mechanics of China University of Science and Technology.

Being detained

In p>1949

When the news of the birth of the People's Republic of China reached the United States, Qian Xuesen and his wife Jiang Ying discussed returning to the motherland as soon as possible to serve their country. At this time, the United States, led by McCarthy, carried out a comprehensive investigation of the * * * producers, and set off a craze in the whole United States to drive employees to be loyal to the US government.

Qian Xuesen's certificate to participate in confidential research was suddenly revoked by the US military department because he was suspected of being a * * * producer and refused to expose his friends. Qian Xuesen was very angry and used it as a reason to ask for returning to China.

in p>195, when Qian Xuesen went to the port to return to China, he was stopped by American officials and put in prison. At that time, dani Dan A. Kimball, the undersecretary of the US Navy, claimed that Qian Xuesen was worth five divisions wherever he went. Since then, Qian Xuesen has been persecuted by the American government and lost his precious freedom. He lost about 3 pounds in a month.

Immigration raided his home and detained him on Temina Island for 14 days. He was not released until he received a huge bail of $15, from California Institute of Technology. Later, the customs confiscated his luggage, including 8 kilograms of books and notebooks. It was only after the American prosecutor reviewed all his materials again that he proved his innocence.

Difficult to Return to China

In the early 195s

The news that Qian Xuesen was persecuted in the United States quickly spread to China, and friends in China's scientific and technological circles supported Qian Xuesen through various channels. The CPC Central Committee is extremely concerned about Qian Xuesen's situation in the United States, and the China government publicly issued a statement condemning the US government for imprisoning Qian Xuesen against his will.

In p>1954, by chance, he saw Chen Shutong standing on the Tiananmen Gate in the newspaper as Vice Chairman the National People's Congress Standing Committee (NPCSC). He decided to write to his father's good friend for help. Just as Premier Zhou Enlai was very anxious about this, Chen Shutong, then vice chairman of the National People's Congress Standing Committee (NPCSC), received a letter from the other side of the ocean. He opened it and signed it "Qian Xuesen", originally asking the motherland government to help him return to China.

in April p>1954, the United States, Britain, China, the Soviet Union and France held an international conference in Geneva to discuss and resolve the Korean issue and restore peace in zhina. Zhou Enlai, head of the China delegation who attended the meeting, thought that a group of overseas students and scientists from China were detained in the United States, so he instructed that since the Americans asked British diplomats to dredge relations with us, we should seize this opportunity and open up new channels of contact.

On June 5th, 1954, Wang Bingnan, Secretary-General of the China delegation, began preliminary talks with the American representative and Deputy Secretary of State Johnson on the issue of the nationals of the two countries. The United States submitted to China a list of American overseas Chinese and some American military personnel detained by China, asking China to give them a chance to return home.

In order to show China's sincerity, Zhou Enlai instructed Wang Bingnan to make generous concessions in the third Sino-US talks held on June 15th, 1954, and also demanded that the United States stop detaining Qian Xuesen and other China personnel studying in the United States.

However, China's just request was unreasonably rejected by the US. On July 21, 1954, the Geneva Conference closed. In order not to interrupt the communication channel, Zhou Enlai instructed Wang Bingnan and the United States to hold consular talks in Geneva from July 22, 1954. To further show China's sincerity in the Sino-US talks, China released four detained American pilots.

China's concession was ultimately aimed at getting Qian Xuesen and other scientists studying in the United States to return to China as soon as possible. However, on this key issue, American representative Johnson insisted that China could not give the real reason why Qian Xuesen wanted to return to China.

In 1955, after Premier Zhou Enlai's continuous efforts in diplomatic negotiations with the United States-even including the release of 11 American pilots captured in the Korean War-on August 4, 1955, Qian Xuesen received a notice from the US Immigration Bureau allowing him to return to China.

On September 17th, 1955, Qian Xuesen's wish to return to China was finally realized. On this day, Qian Xuesen boarded the ship "President Cleveland" with his wife Jiang Ying and a pair of young children, and embarked on a journey to return to the motherland. On October 8, 1955, Qian Xuesen's family finally returned to their haunted motherland and their hometown.
