Introduction to Shenlong Cave: Shenlong Cave was originally called Chuanshan Cave. The structure of the main cave is simple. During the development process, the main gullies of the Liangcha River eroded strongly and cut through the cave wall, dividing the main cave into upper and lower sections. To the west of the cave entrance is the upper section, which is 220 meters long and consists of two corridors sandwiching a hall. It is one of the best attractions for teaching and tourism.
