Introduction to Tiangong Rock: Tiangong Rock is a rock top with a huge span formed by the horizontal splitting of geological structural fault rocks. The top of the rock is flat and spectacular. The cave was formed by the erosion of the underground river in the cave. The cave is dotted with pools and lakes. The lake surface is well-proportioned and the scenery is magnificent and wonderful. The underground river in the cave flows out through the rocks, forming a huge waterfall 10 meters high and more than 20 meters wide at the drop point, forming a rare cave waterfall spectacle.
