It is believed as the final dwelling place for people's souls. Another is Jade Dragon, the spititual prop of the Naxi. The God of Jade Dragon, Sanduo, is the greatest protector of the Naxi people. In the Tang Dynasty, the king of Dali, Yi mouxan, in the ceremony of worshiping the Great Five Mountains, granted Jade Dragon as the North Holy Mountain. He also ordered people to build a temple at the foot of the mountain for worshiping the God Sanduo.

The Naxi people divide snow-mountains into white, green and black. The snow-mountains with glaciers are green ones. There is a big serac forest in the areas with an elevation of over 4500 meters in Jade Dragon Snow Mountain. In the daytime, with the rise of temperature, the snow covering the serac melts and ice with light green color appears. Together with bright sunshine and blue sky, the seracs will shine with green color. Thus, we can see the spectacular sight of "Green Snow."
