The most interesting thing about ssanglong cave is that between the outer cave and the inner cave, there is a huge rock covered on the first-class clear spring, the waterway is wide, the rock bottom is only about one foot from the water, and the inside cave is only used. The boat is lying directly on the bottom of the boat. The boat is penetrated from the water surface of the rock bottom. When it passed through the middle of the rock bottom, it seemed that the surrounding rocks were squeezed together towards the body, and the rock almost wiped its nose. It entered about two or three feet, and suddenly it was open and known as a spectacle. The inner hole was about 2,000 square meters and the cave was deep. On the shore of the boat, looking up, there is a blue stalactite from the top of the northeast cave, and a yellow stalactite from the northwest dive, people called "sanglong", dragon shape is clear and discernible, the image is realistic. In the cave, stalactite is strange and crisscrossed.
