The real paradise, in my opinion, is dam. What is special about Bamei is that it is surrounded by mountains. Since ancient times, the entrance and exit of the stockade has relied on two natural limestone lava caves in the village. The water caves are more than 800 meters long. The villagers need to climb in and out of the long and deep water hole. Because of the inconvenient traffic, the dam has been isolated for years and is not disturbed. This is the real "peach flower source" by Tao Yuanming.
