Elevation of Yin-Yang Boundary Line of Xiling Snow Mountain

More than 3000 meters. Yin-Yang boundary, a scenic spot of Xiling Snow Mountain in Sichuan, is a big pass on Baishagang of Xiling Snow Mountain. The dividing line between Yin and Yang is between Sun Moon Lake and Hong Shijian, which is more than 3000 meters above sea level. The jagged dolomite is shining with silver, the ridge top is only 2 meters wide, and the rock wall is like a knife and axe. It is not only a watershed, but also a dividing line between different climates. The climate in the west is cold and dry in the Qinghai-Tibet Plateau, and the climate in the east is warm and humid in the basin. These two different air currents meet on Baishagang, forming a strange weather: on one side, Wan Li is clear and the sky is blue; On one side, there are clouds steaming and fog surging, and the hazy world. "Yin and Yang" are distinct and varied, which is rare in the world.
