Introduction to the Hanging Spring Waterfall (Dongxiaotianchi Lair Waterfall): The cliff on the north bank of Dongxiaotianchi is nearly 100 meters high, so it is called "Hundred Meter Cliff". Every late spring and early summer, when the ice and snow melt, the water in the pool rises and leaks down from the north bank, forming a nearly 100-meter-high waterfall with flowing silver and jade, splashing down, and the water sounds like thunder.
