Qabiao language

Qabiao, Pu Peo or sometimes Laqua (autonym: ; Chinese: Pubiao 普标, Vietnamese: Pu Péo) is a Kra language spoken by the Qabiao people in northern Vietnam and Yunnan, China. Alternative names for Qabiao include Kabeo, Ka Beo, Ka Bao, Ka Biao, Laqua, Pubiao (Pupeo or Pu Péo) and Pen Ti Lolo (Bendi Lolo). The meaning of the name "Qabiao" is unknown.

Maza, a Lolo–Burmese language spoken near the Qabiao area, is notable for having a Qabiao substratum (Hsiu 2014:68-69).
