In such an inconspicuous town on the east side of Qinghai Lake, there is such a command post that is important to China's atomic bomb construction. From the street of the town, I accidentally walked through it and didn't notice it at all. If it weren't for the billboard at the door, I thought it was a general town building, a small building, a small yard, and it felt like a small street community activity center or a police station. Compared with the auditorium in the town center, the hidden place is really well done. In summer, many tourists will come here, but in winter, especially during the Spring Festival holiday, it is not open.
