Mt. Mira is an important boundary mountain of landform, vegetation and climate on the East and west sides of the Yarlung Zangbo River Valley. It is not only a watershed between the Lhasa River system in the northwest and the Niyang River system in the southeast, but also a natural dividing line between the marine climate in Linzhi and the inland climate in Lhasa. Mt. Mira Pass is located at an elevation of 5013 meters above sea, standing at the mouth of the mountain, blowing vigorously, under the blue sky and white clouds, with multicolored channels on the land and the earth. Swaying between the heavens, continuing to heaven and earth, will convey the pious wishes of Tibetans to the gods of heaven.
