The Cheung Chau Bun Festival returns this weekend for a whole lot of fun (and bun) things to do, see and eat. On Saturday check out the piu sik parade from 2-4pm, in which kids dress up and “float” on poles around the island. At 11:30pm on Saturday don’t miss the Bun Scrambling Competition, where contestants scale an enormous bamboo tower studded with “lucky” buns. Want a taste? Islanders will give out buns on Sunday at 9pm at Pak Tai Temple Plaza. May 13-15. Cheung Chau.
