The Ban Vuong worshipping ritual of Dao ethnic people.

Ban Vuong is considered the primitive ancestor of the Dao families and it is also known as the ghost of the house (a good ghost however). Ban Vuong is worshipped together with the ancestors and five other deities including the gods of rice, arts, hunting, and the two gods of breeding. During important rituals such as the "Cap Sac" (coming of age) ritual, the Dao people must worship Ban Vuong.

In addition to common offerings, a tray of offerings to Ban Vuong must include a pair of “holy pigs” and two bottles of “holy wine”. After selecting a blessed date, the householder invites three shamans to host the ritual.

In the past, the Ban Vuong worshipping ceremony used to take place over 3 days and 3 nights. Today, it is simplified but its sacred nature and value have still been kept intact. During the ceremony, the shamans invite Ban Vuong to witness the household's sincerity. At the end of the ceremony, the priests burn votive papers to return Ban Vuong to his underworld.

The Ban Vuong worship ritual is a humane ceremony as it encourages people to remember their ancestors. In addition, this ceremony also establishes a link strengthening the community and the relationships between both family members and among villagers.
