Did you freeze in winter? Then come to the underground Grand Canyon of Lishui, and keep the ambient temperature of 20 degrees all year round, very pleasant. In the underground Grand Canyon, the lights are flashing, the stream is flowing, the shape of the stalactites on both sides of the stone wall is strange and varied, and with the fascinating light, the whole cave is eccentric, and it feels like entering a fairyland. When you float in the stream, people are in the middle of the painting. The cave is really a mysterious adventure.
