In China, Lashi (Leqi) speakers are distributed in Mangshi City (formerly Luxi County), Ruili City, Longchuan County, and Yingjiang County of western Yunnan Province (Dai 2007:5). Mangshi has the most Lashi speakers, who are distributed in the following townships. Lashi (လရှီ) is also spoken in eastern Shan State, Burma. Lashi was originally spoken in the downstream area of the Ngochang Hka river valley, a tributary of the N’Mai Hka river, while Ngochang was originally spoken in the upstream area of the Ngochang Hka river valley.
