Changling Mountain is located in Gulang County, Wuwei City, Gansu Province, and belongs to Qilian Mountain National Nature Reserve. From the Tang and Song Dynasties to the Qing Dynasty, the temples on the hills are row upon row, the cigarettes in the mountains are lingering, and the sounds of the morning and the faint bells echo, and the celebrities and monks who come near are esoteric. There is the name of "Northwest Xiaowudang". On the Changling Mountain, the trees and flowers are lush, and the arbor trees such as spruce, pine, and aspen are all over the mountains. Autumn also dyed the autumn grass on the mountain. Over the years, it has blocked the raging yellow sand with its own barrier, blocking the footsteps of the desert invasion, and is known as a green pearl embedded in the desert. In 1989, Changling Mountain was listed as a national nature reserve.
