Introduction to Mu Banghai: Mu Banghai is another representative of the beauty of Jiaozi Mountain. Through glaciation, Jiaozi Mountain has formed many glacial depressions, glacial troughs, cirques and other glacial terrains. Some depressions accumulated water during the late glacial period, forming glacial lakes. In Jiaozi Mountain, glacial lakes are mainly distributed at an altitude of 3000-3950 meters. There are nearly a hundred lakes in number, but their area is very small. Mubanghai is one of them.
