The Dao consider themselves to be the descendants of Ban Vuong or Ban Ho, a legendary character of the Dao people.
Overtime, the Dao people in China were divided into small groups and they migrated to different places, with some of them coming to Vietnam. During the migration, the different groups incorporated some cultural practices of other nations, creating new, diverse Dao cultures. However, the different groups still maintain a common Dao identity, as they have the same origins and continue to share a common language.
Red Dao people mainly live in Cao Bang, Lang Son, Tuyen Quang, Ha Giang and Lao Cai. Nowadays, Ta Phin village has more than 700 Red Dao people.
