The Yao include numerous local groups, each with it's own charateristics of language, costume, and custom. The Yao have been in Vietnam since the 13th century, and live dispersed throughout most of the mountainous and midland provinces of the north. In the document Binh ho-ang khoan diep or Qua son bang, the dog-dragon Pan Hu (Ban Vuong) was identified as the Yao's founding ancestor. These documents of the migration history of the 12 origi-nal Yao lineages have been transmitted from generation to generation.
The Yao cultivate wet-rice or swidden fields, depen-ding on the soil conditions, and grow various kinds of fruit trees, and medical plants. Animal husbandry and poultry raising are well developed. The Yao also make a wide vari-ety of traps for hunting birds and game. Their handicrafts include black smiting, weaving, and papermaking.
Iniation ceremonies are organized for young men. These are Taoism rituals. Folk culture, particularly litera-ture, is very rich and varied among the Yao.
