The jiao is the largest thing Taoism does. It is a communal offering ritual that renews the covenant between a settlement and the powers governing it, performed over several days by hired priests holding the appropriate registers, and paid for by subscription from every household in the district. The sequence involves establishing and sealing a sacred area, inviting the gods by written memorial, a confession made on the community's behalf, the presentation of offerings including a whole pig, the reading of the community's register of subscribers to heaven, and finally the dissolution of the altar and the burning of everything used. Opera is staged on a temporary platform facing the temple, and it is performed for the gods, with the human audience incidental. Hong Kong's Taiping Qingjiao, held by New Territories villages at intervals of ten years or longer, is inscribed on the territory's intangible cultural heritage list, and the associated Cheung Chau bun festival is nationally famous. Some communities hold theirs once in sixty years, meaning most residents will see one.
