He is a great contemporary scientist. He not only led the team to develop the atomic bomb for China, but also made many contributions to the development of atomic energy science in China, and even trained the atomic energy science and technology team for China. It can be said that China's self-improvement today is inseparable from Mr. Qian Sanqiang's achievements.

Mr. Qian Sanqiang graduated from Tsinghua University, and completed his doctoral thesis "Collision between Alpha Particles and Protons" on 1939. 1959 when sino-Soviet relations were cold, many Soviet scientists were recalled in the middle of aid projects, including the most important nuclear technology agreement.

At that time, Mr. Qian Sanqiang was the main person in charge of the development of nuclear weapons. Under heavy pressure, relying on incomplete information and risking their lives at any time and place, China finally successfully developed an atomic bomb in 1964, which changed its position in the international military armed forces. Mr Qian Sanqiang is also a "two bombs and one satellite" in China.

The story of Qian Sanqiang's name:

Mr. Qian Sanqiang was originally named Qian Bingqiong, a native of Shaoxing, Zhejiang. There is a story about why his name is Qian Sanqiang.

When he was young, he had a friend who was in poor health. His nickname is David. David wrote a letter to Mr. Qian Sanqiang, calling him "the top three" in his heart, which was seen by Mr. Qian Sanqiang's father. Hearing the reason, Mr. Qian Sanqiang replied, "David called me' Top Three', because I ranked third at home, because I have strong athletic ability and because I am in good health.

Qian Fu is also a casual person. He felt that since his son liked it, he simply changed Qian Qiubing to Qian Sanqiang.
