In the mid-1950s, although China's computing technology was only one or two years behind Japanese, it was ten years behind the appearance of the first electronic computer in the world. The unanimous opinion is: first learn and master the existing technology of the Soviet Union, and then carry out our own research work according to the specific situation of our country, that is, "imitate first and then innovate, and imitate for innovation".

1956 In September, China sent a delegation of computing technology to the Soviet Union. Head Min Naida, deputy head, members include Wu, Fan Xinbi, Xia, Zhou Shouxian, Sun Su, Mo Gensheng, Xu Xianyu, Yan Youguang, translators Zhang Wei, Mu Lili, etc. The receiving unit of the former Soviet Union was the Institute of Precision Machinery and Computing Technology of the Soviet Academy of Sciences. In more than two months, the delegation visited the research, production and education of computing technology in Moscow and Leningrad respectively, and focused on the M-20 computer. ?

1April, 957, China ordered the drawings and materials of M-3 computer and бэсм computer through government channels. On the basis of investigation and obtaining drawings, the development work was started. M-3 (code 103) computer engineering group headed by Zhang Zichang and Mo Gensheng was established. Through the efforts of all scientific researchers and the close cooperation of Beijing Cable Power Plant, the first digital electronic computer in China was successfully developed on1August 998 1958+0. This electron tube computer with an operation speed of 30 times per second fills the blank of modern electronic computers in China.

August 1958, 1, 103 computer developers gathered in front of the machine to celebrate the birth of the first digital electronic computer in China.
