Cheung Chau Bun Festival ( 包山節) or Cheung Chau Da Jiu Festival ( 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.
Cheung Chau's Bun Festival, which draws tens of thousands of local and overseas tourists every year, is staged to mark the Eighth day of the Fourth Moon, in the Chinese calendar (this is usually in early May). It coincides with the local celebration of Buddha’s Birthday.
