Bisu (Chinese: 毕苏语) is a Loloish language of Thailand, with a couple thousand speakers in China. Varieties are Bisu proper (Mbisu) and Laomian (Guba), considered by Pelkey to be distinct languages.
The Laomian are classified within the Lahu ethnic group; the Lahu proper call them the "Lawmeh".[2]
According to Bisuyu Yanjiu 毕苏语研究 (2002), there are over 5,000 Bisu speakers in Yunnan, China, and a total of nearly 10,000 Bisu speakers in all countries combined. Within Yunnan, it is spoken mostly in Pu'er Prefecture, as well as neighboring parts of Xishuangbanna.
