Bisu (บีซู)

Bisu is a member of the Loloish branch of the Tibeto-Burman language family spoken by about 10,000 people. About half of the Bisu speakers are found in Yunnan Province in the south west of China, particularly in Lancang, Menghai, Ximeng and Menglian counties in Pu'er Prefecture, and in nearby parts of Xishuangbanna Prefecture. There are also speakers of Bisu in the Phan District of Chiang Rai Province in northern Thailand, in Phongsali District in Phongsaly Province in northern Laos, and in Shan State in northeastern Myanmar.

Bisu is known as Mbisu, Misu, Mibisu, Mbi or Lao-Phai. It is written with the Thai script in Thailand, using an orthography developed by Kirk Roger Person, a linguist at Payap University and SIL International, his wife Liz, and Bisu-speaking people in northern Thailand starting in 1997. The Thai script for Bisu was revised in the early 2000s, and several hundred publications were published in the language. The Latin alphabet is used in Laos and Myanmar to write Bisu using a spelling system based on Lahu.
