Known as Bo Bing (博餅), the game involves rolling six dice to determine different prize levels, with titles such as zhuangyuan (狀元), bangyan (榜眼) and tanhua (探花). Mooncakes are traditionally given as prizes, symbolizing good luck, success and prosperity. Anyone can join, including international visitors, making it a fun way to experience a traditional Mid-Autumn custom.According to local legend, the game was created by Hong Xu (洪旭), a Kinmen-born general under Koxinga, to boost the morale of soldiers stationed in Xiamen and ease their homesickness during the Mid-Autumn Festival. The tradition later spread across Kinmen, Xiamen and Quanzhou before reaching Taiwan.Date: September 1-25Location: Kinmen Military Headquarters of the Qing Dynasty, KinmenEvent Highlights: More than 130 participating shops: Visitors can collect Bo Bing tokens by shopping at participating stores during the festival.
