Gêrzê
Gêrzê belongs to the high pastoral country of Changtang in western Tibet. The local historical account identifies Sengguo herders as an established community and records an eighteenth-century arrival of migrants from Qinghai and the Amdo area around Nagqu. Their settlement formed two major tribal groupings. The district’s population and social geography therefore changed during the eighteenth century, rather than remaining an unchanging expanse of wilderness.
