The northern Tibetan grassland is the largest natural grassland in Tibet, located between the Kunlun Mountains, the Tanggula Mountains and the Gangdise Mountains, with an average altitude of more than 4,500 meters. Yaks and herders' tents are scattered all over the place, forming a unique landscape. The biggest feature is its vastness and magnificence. It is not only a paradise for yaks and sheep, but also a fertile land of culture, where well-preserved nomadic culture can be seen.
