Qian Xuesen, the story of returning to China in five years.

1On October 6th, Qian Xuesen, his wife and a dozen China students studying in the United States spent the Mid-Autumn Festival in a street park near California Institute of Technology. They talked excitedly about the great news of the founding of New China and discussed how to return to China to serve as soon as possible. At the end of the following summer, Qian Xuesen loaded his luggage, 800 kilograms of books and notebooks on the American "President Wilson", which was about to sail to Hong Kong, and immediately prepared to take his family back to China by the plane of Canada Pacific Company.

On September 9th, the US Federal Bureau of Investigation arrested Qian Xuesen and put him in a detention center in Termina Island, where he was brutally tortured. Later, due to Qian Xuesen's protest and the help of American friends, the Immigration Bureau had to release him, but he was still under surveillance.

The outrageous obstruction of the American authorities did not lock Qian Xuesen's heart in returning to China. He and his wife Jiang Ying continued to fight in various ways.

After returning to California Institute of Technology, Qian Xuesen devoted himself to the research of engineering cybernetics, and published more than 300,000 words of English "Engineering Cybernetics" from 65,438 to 0954 in the United States. Qian Xuesen conducted this research, on the one hand, to show China people's talent in engineering technology, and on the other hand, to show the American authorities that he has changed the original research direction of jet propulsion, and to eliminate the excuse that they did not allow him to return to China. Mrs Jiang Ying is a singer who was born in China and studied in Germany. She understands her husband's situation and mood very well. At that time, FBI agents often broke into Qian Xuesen's office and residence. In order to prevent accidents, she neglected her major and resolutely stayed at home to do housework in order to take care of her husband and children. In those difficult years, Qian Xuesen always set up three light boxes at home so as to leave for home at any time.

1June, 955, Qian Xuesen got rid of the spy's surveillance. In a letter written on a small cigarette paper to his Belgian relatives, he sent a letter to Chen Shutong, then vice chairman of the National People's Congress Standing Committee (NPCSC), earnestly requesting the production party and government of China to help him return home. This letter was quickly forwarded to Premier Zhou Enlai. In August 1955, 1, China and the United States held ambassadorial talks in Geneva, and discussed the issue of expatriates in the two countries in detail. On the condition of releasing 1 1 American pilot prisoners of war, China demanded that the United States stop obstructing Qian Xuesen and other China students studying in the United States to return home. Under the negotiation of the China administration, the US immigration authorities finally had to agree to release Qian Xuesen.

Because Qian Xuesen returned to China, China's missiles and atomic bombs were launched at least 20 years earlier. Qian Xuesen was praised by westerners as the "father of missiles" in China.
