Cheung Chau Bun Festival (traditional Chinese: 包山節) or Cheung Chau Da Jiu Festival (traditional Chinese: 長洲太平清醮) is a traditional Chinese festival on the island of Cheung Chau in Hong Kong. Being held annually, and with therefore the most public exposure, it is by far the most famous of such Da Jiu festivals, with Jiu (醮) being a Taoist sacrificial ceremony. Such events are held by mostly rural communities in Hong Kong, either annually or at a set interval of years ranging all the way up to once every 60 years (i.e. the same year in the Chinese astrological calendar). Other places that may share the folk custom include Taiwan, Sichuan, Fujian and Guangdong.
