The champion cake is also called "Bo champion" and "Bo Mid-Autumn Festival", commonly known as "Bo cake". There are different reasons for this. One is that in the late Ming and early Qing Dynasties, the king of Yanping County, Zheng Chenggong's department, designed a game designed by Hong Xu based on the name of the imperial examination system to express the sadness of soldiers conquering the north and the south and leaving their homes. Hong Xu was a native of Kinmen, and the game of gambling was spread to Taiwan and became a custom of the autumn festival. During the Mid-Autumn Festival, the whole family sits in a group, and they can't help but flex their hands and experience the fun of "bo champion" in one fell swoop. Winning the champion cake also has a good luck this year and everything goes smoothly.
