Introduction to Water Curtain Cave: On the half-way wall of Baihu Mountain on the opposite bank of Moonlight Island, there is a waterfall that cascades down into the Li River. As the boat approaches the wall, splashing beads and droplets hit the face. No matter how big the water is, it is not turbid. No matter how dry the weather is, it never dries up, and within twenty or thirty miles there are high mountains and no source of water can be found. Crossing the cliff and exploring the Shuiliandong Cave, surrounded by dangers, is a favorite place for adventure lovers.
