Lisu (ISO 639-2 lis) is spoken by just over a million members of the group of this name in south-western China, north-eastern Burma, northern Thailand and north-eastern India. It formerly also had other names used by outsiders, including Yeren (Chinese yeren ‘wild people’), and Yawyin in Burma and Yobin in India (both derived from the Chinese term). Other names included Lisaw from the Shan and Thai name for the group, also seen in the former Burmese name Lishaw. About two-thirds of the speakers live in China, especially in north-western Yunnan Province, but also scattered elsewhere in Yunnan and Sichuan. About a quarter live in the Kachin State and the northern Shan State in Burma, with a substantial number in Chiangmai, Chiangrai and other provinces of Thailand, and a few thousand in Arunachal Pradesh in India. It is also spoken as a second language by many speakers of Nusu, Anung, Rawang and others in north-western Yunnan and northern Burma. Lisu has almost completely replaced Anung in China and is replacing Lemei in China. The Lisu are one of the 55 national minorities recognised in China, one of 135 ethnic groups recognised in Burma, a scheduled (officially listed and recognised) tribe in India, and one of the recognised hill tribe groups of Thailand.
