Jinhua Palace National Mine Park, this is an attraction I accidentally punched in when I came to Datong. It was snowing in the sky. I just returned from Hengshan and saw such a mine park on the map, so I walked in. Although some exhibition halls are not open, for example, look at the mines. But I had a deep exchange with the miners, learned about their daily work and life, and finally left in the miners' shuttle bus, believing that the park will become very mature and commercialized now.
