Introduction to Baima Village: The Baima people are the descendants of the ancient Di people, and Pingwu County has been an area inhabited by the Di and Qiang ethnic minorities since ancient times. The Baima people in the county are mainly distributed in Baima, Muzuo and Mupi and Huangyangguan and other four Tibetan townships. Due to the lack of ethnic identification conditions at the beginning of liberation, they were identified as Tibetans and were customarily called Baima Tibetans. In fact, the Baima people were a force left behind by the Tubo Dynasty's Eastern Expedition. They were different from Tibetans in that they had their own language and Culture, and the name has a surname, which is obviously different from the Tibetan people.
