A huge natural cave on the Chuandong River runs through the mountains and behind the mountains. It is magnificent, about 80 meters high and about 30 meters wide. It is also one of the natural scenery of Guangxi. Her front hole is cut on both sides and the left and right, as if the ancients deliberately left the inscriptions for the future. The roof of the cave is curved and twisted, and the natural construction of hundreds of millions of years makes the landscape of the cave strange and unique. The stalactites of various sizes in the cave are in shape, forming a moving pattern of the shape.
