Macro-Bai is a grouping of the
Bai languages, spoken in the Chinese province of
Yunnan, with the recently discovered
Caijia language spoken in western
Guizhou.
Longjia and
Luren (also from western Guizhou) may be closely related to Caijia, and therefore also be part of Macro-Bai. Bai has over a million speakers, but Longjia and Luren may both be extinct, and Caijia is highly endangered, with approximately 1,000 speakers. The
Qixingmin people of
Weining County, Guizhou may have also spoken a Macro-Bai language.
