What obstacles did Qian Xuesen encounter when he returned to China?

After his return to China, Qian Xuesen was repeatedly obstructed by the United States, including revocation of his research certificate, imprisonment, confiscation of luggage, persecution and so on.

1, revocation of confidentiality research certificate

1949, when the news of People's Republic of China (PRC)'s birth reached the United States, Qian Xuesen and his wife Jiang Ying discussed returning to the motherland as soon as possible to serve the country. At this time, the United States, led by McCarthy, conducted a comprehensive investigation on the producers of * * *, and set off a craze in the 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 of * * * and refused to expose his friends. Qian Xuesen was very angry and asked to return to China on this ground.

Step 2 go to jail

1950, when Qian Xuesen went to the port to prepare for returning home, he was stopped by American officials and put into prison. Dani king Bull, then undersecretary of the US Navy, claimed that Qian Xuesen was worth five divisions wherever he went. From then on, Qian Xuesen was persecuted by the American government and lost his precious freedom.

3. Seizure and detention of property

Immigration raided his home and detained him in Temina Island for 65,438+04 days. He was not released until he received a huge bail of $65,438+$5,000 from California Institute of Technology. Later, the customs confiscated his luggage, including 800 kilograms of books and notebooks. He didn't prove his innocence until the American prosecutor reviewed all his materials again.

Step 4 write for help

In the early 1950s, 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 Central Committee of the Communist Party of China 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. ?

1954 By chance, he saw Chen Shutong standing at the gate of Tiananmen Square as the vice chairman of the National People's Congress Standing Committee (NPCSC) in the newspaper, so he decided to write to his father's good friend for help.

Just as Premier Zhou Enlai was 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. ?

1954 in April, the United States, Britain, China, the Soviet Union and France held an international conference in Geneva to discuss the settlement of the Korean issue and restore peace in zhina. Zhou Enlai, head of the China delegation attending the meeting, thought that a group of overseas students and scientists in 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 5, 2004, Wang Bingnan, Secretary-General of the China delegation, held preliminary talks with US representative and Deputy Secretary of State Johnson on the national issues of the two countries. The United States submitted to China a list of overseas Chinese and some American soldiers 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 in June 1954, and also demanded that the United States stop detaining Qian Xuesen and other China students studying in the United States.

However, China's just request was unreasonably rejected by the United States. 1954 on July 2 1 day, the Geneva conference closed. In order not to interrupt communication channels, Zhou Enlai instructed Wang Bingnan to agree to hold consular talks in Geneva from July 22nd. 1954. To further demonstrate China's sincerity in the Sino-US negotiations, 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. But on this key issue, US Congressman Johnson still refuses to let go of the real reason why China sent Qian Xuesen back to China.

Step 5 negotiate repeatedly

From 65438 to 0955, after continuous efforts of Premier Zhou Enlai's diplomatic negotiations with the United States-even including the release of 1 1 American pilots captured in the Korean War, Qian Xuesen received a notice from the US Immigration Bureau allowing him to return to China on August 4, 1955.

1September 1955 17, Qian Xuesen's wish to return to China finally came true. On this day, Qian Xuesen, his wife Jiang Ying and a pair of young children boarded the ship "President Cleveland" and embarked on the journey of returning to the motherland. 1On October 8th, Qian Xuesen's family finally returned to the haunted motherland and hometown.
