Qian Xuesen, born in Hangzhou, Zhejiang Province,19111was born in Shanghai in February. His father is Qian Junfu, his mother (I really can't remember the name of Qian Furen), and Qian Xuesen is the only child in the family. Qian Xuesen moved to Beijing with his parents when he was 3 years old. At the age of 6, he began to study in the experimental primary school and experimental middle school affiliated to Beijing Normal University. 1929 was admitted to department of mechanical engineering Railway Machinery Department of Shanghai Jiaotong University, 1934 graduated (Master Qian dropped out of school for one year due to physical reasons when he was a sophomore). 1934 After graduating from university, he was awarded a scholarship from boxer indemnity to study in the United States. After working as an engineer at Jianqiao Airport in Hangzhou for one year, 1935 crossed the ocean to study in the United States in the summer. He studied at Massachusetts Institute of Technology and California Institute of Technology, and studied under the world aerodynamics master von Carmen. He received his doctorate in aeronautical engineering and applied mathematics at 1939. Later, under the recommendation of Professor von Carmen, he entered the Guggenheim Jet Propulsion Laboratory of the US Air Force to engage in top secret research of the US Air Force, and served as the deputy director of the laboratory at 1946. At the same time, he became the youngest tenured professor at MIT. 1947, Qian Xuesen married Ms. Jiang Ying, the daughter of Mr. Jiang Baili, a famous strategist in the Republic of China, in the United States, and they had a son and a daughter (Qian Yonggang) after the marriage.

Carol: When I left, his second child was just born. He gave the child diapers and other things. Five years later, he took them back to China without unpacking them. My youngest son was born at that time, and he gave them to me.

That is, after the five-year secret buffer period,1one day in June, 955, Jiang Ying accompanied Qian Xuesen to pretend to wander in the street. They cleverly avoided the spy's tracking and quickly slipped into a cafe. While drinking coffee, Jiang Ying asked his students to write a letter in Chinese with cigarette boxes as paper.

Jiang Ying: One Sunday, the students all picked up their pens and wrote a few simple words, saying that we were looking forward to returning to the motherland after liberation day and night, but the American government is now imprisoned by the American government, and we can't do it. So how can we send this letter? Because we are surrounded by spies who watch us day and night, the letter is written by students and the envelope is written by me. I copied the children's notes so that they wouldn't recognize them. This letter is addressed to my sister in Belgium.

After many twists and turns, this short message finally reached Zhou Enlai. On August 1955 and 1, Ambassador Wang Bingnan put Qian Xuesen's letter and its translation on the negotiating table at the fifth Sino-US ambassadorial talks. In exchange, China released 12 American pilots. A few days later, it took Qian Xuesen five years.

After bidding farewell to his mentor von Carmen, Qian Xuesen boarded the Cleveland President with his wife Jiang Ying, young child Qian Yonggang and youngest daughter Qian Yongzhen and set off for home. At this time, the real legend of Qian Xuesen has just begun.
