Hmu has been recognized as a branch of Hmongic since the 1950s. Wang (1985) recognized three varieties. Matisoff (2001) treated these as distinct languages languages, which is reflected in Ethnologue. Lee (2000) added a fourth variety, Western Hmu (10,000 speakers), among the Yao, and Matisoff (2006) lists seven (Daigong, Kaili, Lushan, Taijiang, Zhenfeng, Phö, Rongjiang ).
