One of Hong Kong's most colourful cultural celebration event, Cheung Chau Bun Festival, will be staged on 25 May 2015 (Monday) till 26 May 2015 midnight (Tuesday). This festival has over 100 years of history. Every year, thousands of people descend upon the tiny island for The Piu Sik (Floating Colours) Parade, Lucky Bun (Ping On Bun) and The Bun Scrambling Competition, the ancient custom during the festival. The tradition has been passed down for generations. To ensure the tradition keeps passing on, every year, Cheung Chau Islanders fuse the new elements with the custom to draw the attention from the young. This year, “K-Pop stars” will be featured by one of the Piu Sik parade teams, the first-ever “Ping On (Lucky) Macaron” with Chinese tea favour is invented, and more to be found out on the island.
