Introduction to Xishui Cave: Xishui Cave is far away from Lingyun Cave. The cave is 270 meters deep. There are more than 40 painted clay sculptures in the cave, which display the strong Taoist culture. It is said that Han Xiangzi, one of the Eight Immortals, once lived here. He attained the Tao and became immortal, so it was regarded as the fifty-fifth blessed land of Taoism.
