リス族
The Nu people, originating in the Tibetan Plateau, may have inhabited the areas of the Salween (Nu) and Mekong (Lancang) in modern day China as early as 2000 BCE. The Wa people, who today inhabit parts of the Salween basin on both sides of the China–Burma border, migrated south along the river from Tibet around 500–300 BCE. The Lisu people, also originating in Tibet, arrived in Yunnan sometime before 1000 CE. Chinese records begin to mention Lisu in the late Tang Dynasty (618–907 CE). The Lisu originally inhabited areas further east in Yunnan, but over centuries they were pushed north and west towards the Salween as more Han people settled in Yunnan.
