Introduction to Longquan Rock: Longquan Rock is 1,256 meters long. It is composed of numerous karst caves and underground rivers. The cave is like a rotating hall divided into upper and lower floors. In the lower water cave, a clear stream meanders. It is about 1,000 meters winding. The bottom is sand and gravel, and you can swim through the water. The stalactites, stalagmites, stone mantles, stone flowers and stone pillars in the rock are in various shapes and lifelike. What's even more surprising is that there are thousands of large bats living in the cave, hanging upside down in series, forming a beautiful landscape.
