Ai-Cham (autonym: ; ) is a Kam–Sui language spoken mainly in Diwo 地莪 and Boyao 播尧 Townships, Jialiang District, Libo County, Qiannan Prefecture, Guizhou, China. Alternative names for the language are Jiamuhua, Jinhua and Atsam. Fang-Kuei Li first distinguished the language in 1943. Nearby languages include Bouyei and Mak. However, Yang (2000) considers Ai-Cham and Mak to be different dialects of an identical language. Ai-Cham has six tones. Regarded of speaker's nationality, they are being subsumed under "Bouyei" nationality (same with speakers of Mak language). The mythical patriarch and hero of the Ai-Cham people is the demigod Wu Sangui, who is celebrated during the Ai-Cham New Year.
