This lake flows from Xi 'er River to Xiaguan, Dali, and flows westward into Yangbi River.

Erhai Lake has seven functions: water supply, agricultural irrigation, power generation, climate regulation, fishery, shipping and tourism. Cangshan is like a screen in the west of Erhai Lake and faces Yushan in the east, with a beautiful space environment.

Its main protection objects are plateau freshwater lakes, aquatic animals and plants, natural landscapes and glacial remains in the transitional zone between north and south animals and plants, covering an area of 79,700 hectares.

The spring water was snatched from the sand and gathered in a pond of more than 20 square meters. The spring water is green and clear, surrounded by marble railings and green trees. There is an ancient double-fragrant tree lying across the spring surface, reflecting in the water, swaying and changing endlessly.

Every year in April of the lunar calendar, butterflies gather at the spring and dance, and some of them are hung on trees end to end, forming the wonders of butterfly spring. There are also butterfly museum, sea pavilion, butterfly monument, Xu Xiake stone statue and so on.
