Jiekexili Nature Reserve is located in Yushu Tibetan Autonomous Prefecture in southwestern Qinghai Province, but the whole area of Kekexili includes the "Qiangtang Grassland" area in northern Tibet, the area south of Kunlun Mountain in Qinghai Province and the area adjacent to Tibet and Qinghai. Cocoacili is known as the "forbidden zone of life" because of its cold climate and harsh natural conditions, which make it impossible for human beings to live for a long time.
