Traveling to Tibet, we set out from Nima County to Shuanghu County. On the way, we passed the Qiangtang Grassland, an uninhabited area. It is also one of the five largest pastures in China. It is located between the Kunlun Mountains, Tanggula Mountains and Gangdise Mountains. It is also a paradise for wild animals and plants. The average altitude of the Qiangtang Grassland is above 4,500 meters. It is the largest pure natural grassland in Tibet, with Gobi, grassland, lakes, mountains and rivers. The Qiangtang Grassland covers a wide range, including most of the northwest of Nagqu Prefecture, the eastern part of Ali Prefecture, a small part of the north of Shigatse City, Dangxiong County of Lhasa City and a small part of the southwest of Qinghai Province.
