Extended data

Factory 420 was moved from Shenyang in 1958, and its main product is the production of aircraft engines. 420 is their code name, which was kept secret in previous years. At that time, all communications had to be written as "Box 77", and the 420 factory was moved to Sichuan, which was part of the huge third-line factory plan in China at that time.

Chengdu Engine Group (State-owned 420 Factory) was once one of the largest military enterprises in Southwest China. At its peak, it had about 20,000 workers and 654.38 million+family members. At that time, Shuangqiaozi was basically the factory's world, and after the Second Ring Road was the dormitory of the factory. When I transferred to Sichuan, I called Xindu Machinery Factory first. In fact, this factory is located in Shuangqiaozi, so it is called secrecy. Now it has moved to the eastern suburbs of Chengdu.
