In January, I went from Kaili to the ancient town of Jiuzhou and then to the Yang Wharf Reservoir. Follow the navigation and drive directly to the reservoir, but the road into the reservoir was blocked. The villagers said that there was a gap that people could go in and find that it was not far away. In fact, it was still far away. The weather was good. I could see the mountains and the distance. A piece of water seems to be an illusion that it was once Wuyang Lake. The surrounding villages are rural no villages. It is not old villages. It is very comfortable to see farmers drying corn. Life in this environment is what someone said. This is called the hidden city.
