Deng Jiaxian and Qian Xuesen only have a working relationship. Deng Jiaxian and Qian Xuesen, both academicians of China Academy of Sciences, have made outstanding contributions to China's nuclear and atomic weapons.

Deng Jiaxian (1June 25th, 924-1July 29th, 986), member of Jiu San Society, academician of China Academy of Sciences, famous nuclear physicist, pioneer and founder of nuclear weapons development in China, has made important contributions to the research and development of nuclear weapons and atomic weapons in China.

Qian Xuesen (1911.12.1-2009.10.31), Han nationality, the 33rd Sun Wu of Qian Liu, a Shanghainese, is a ancestor. World-renowned scientist, aerodynamicist, founder of manned space flight in China, academician of China Academy of Sciences and China Academy of Engineering, the launch of missiles and atomic bombs in China was at least 20 years ahead of schedule due to Qian Xuesen's return to China.

Qian Xuesen's Personal Life: 1935, Qian Xuesen went to study in the United States, and Jiang Ying also went to Europe to study in Berlin, Germany with his father. The correspondence between them deepened their feelings. After World War II, Jiang Ying came to the United States. At that time, Qian Xuesen was in his thirties and Jiang Ying was 24 years old. They postponed the wedding again for their respective careers. They didn't get married in Shanghai until 1947.

1In August, 935, Qian Xuesen went to the United States for further study. He was originally majoring in aviation engineering, but he had an argument with his father on the issue of further study. Qian Xuesen intends to study space theory next, but his father wrote back that China's space industry is backward, and it will be beaten if it is backward. It is better to study aircraft manufacturing technology. Qian Xuesen told his father that China lags far behind the West in the field of aircraft manufacturing, and only by mastering space theory can it surpass the West.

Jiang Baili knows the difference between Qian and his son. He told his old friend Qian Junfu that aviation research in Europe and America tends to unify engineering and theory, and engineering follows theory. Hearing this, Qian Junfu finally promised his son to continue studying space theory.
