Plateau Atomic City is located in Xihai Town. In the 1950s, China established the first nuclear weapons research and development base and production base here. China's first atomic bomb and hydrogen bomb have been successfully developed and assembled in the mysterious forbidden zone of 1700 square kilometers. Now it has finally unveiled its mysterious veil to the world and become a unique tourist wonder in China. The base exhibition hall is built by using the original detonation test, also known as the shooting range. It is used for the development of atomic bomb and hydrogen bomb to carry out various welding bomb modes and armor-piercing bomb tests. There are seven exhibition rooms in the base exhibition hall, the first one is the background of the base establishment; the second one is the process of the base establishment; the third one is the successful explosion of two bombs; the fourth one is the brilliant achievement; the fifth one is the glorious retirement and leisure; the sixth one is the peaceful use of swords; and the seventh one is the new appearance of the West Sea. The exhibition room vividly reproduces the construction and development of the base through a large number of pictures, attracting a large number of Chinese and foreign tourists to come here for sightseeing and secrets exploration.
