Qiang people
Tibetan languages belong to the Tibeto-Burman language group. The traditional or mythological, explanation of the Tibetan people's origin is that they are the descendants of the human Pha Trelgen Changchup Sempa and rock ogress Ma Drag Sinmo. It is thought that most of the Tibeto-Burman speakers in Southwest China, including Tibetans, are direct descendants from the ancient Qiang people.
