What surprised me most about the Shuidonggou Scenic Area was the Tibetan Bingdong and the introduction of border defense facilities behind it.

I often climb the Great Wall in Beijing. This time I learned that the Great Wall has bricks, stone blocks, and clay. Ningxia is mainly clay. Seeing the Red Mountain Fort in the Ming Dynasty is really easy to guard! On the left is the Tibetan cave
