404 city, known as Gansu mining area, is an important cradle of nuclear industry. However, due to the conversion from military to civilian, there is a gap with the beginning of construction. At present, we mainly deal with nuclear waste. The family area is now moved to Jiayuguan City. The production plant is still in Yumen, which is the backbone of China National Nuclear Corporation.

Another 404, located in the west of Yumenguan, is a secret nuclear industry production base. 1958, in order to build an atomic bomb, scientific and technological experts from all over the country gathered to build a small town on the Gobi Desert, so if you pass by, you just need to bring your ID card.

Extended data:

There is no 404 factory on the map, and 404 Fiona Fang is deserted for twenty or thirty miles, which is exactly what the radioactive industry needs. At the beginning of 404, the conditions were difficult and sandstorms raged. In order to avoid the wind and sand, people dig holes in the ground, lay thatch and sleep underground.

In addition, the 404 nuclear power plant involves radioactive materials, and the living area of 404 is separated from the factory building. The factory is in the northwest, and it takes nearly an hour by train. The most radioactive job is to go to the pit, and everyone must leave after working in the pit for half an hour.

In addition, the slogan put forward by 404 when it first set up the factory was to dedicate its life to youth and future generations. The original living area centered on workers' clubs and department stores was divided into two areas, north and south, with a market, a primary school and a kindergarten.
