Introduction to Tianxing Cave: Tianxing Cave is located 10 kilometers upstream of the Getu River. The water from Xingxing Gorge enters the undercurrent and flows out of Tianxing Cave. The cave is about 110 meters high and 40 meters wide. The cave entrance is rectangular, with a huge mouth across the cave entrance, and stone curtains hanging on the cave walls. The underground river cave in the cave and the green mountains and green waters outside the cave complement each other, making it elegant and refined, and particularly charming.
