It is said that its origin is related to a legendary story in the Tang Dynasty.
Ming Taizu in the Tang Dynasty liked opera very much. One year, he visited Jiangnan. One day, he took a little eunuch to visit Tangxi Town in Jiashan incognito and heard the sound of silk and bamboo on the slate road. He found one and started. When several old people saw two strangers coming in, they all bowed and offered their seats to tea.
It turns out that there are two mothers and children in this family. The mother is paralyzed in bed and depends on her son to wait on her. Today is the boy's twentieth birthday, and the neighbors pooled their money to invite a troupe to sing country songs and have a good time. Tang felt refreshed, clapped and even forgot to return. Unconsciously, after a long time, they felt hungry. Tang wanted to go to the restaurant for dinner, but he was reluctant to leave, so he quietly told the little eunuch to buy something to eat.
As a result, an old man heard it, and he was busy filling his hunger with cakes made by young people themselves. This is a cake made by grinding white rice into powder. Crispy and sweet, very delicious. Don is very happy because he is full. After he returned to the palace, he suddenly remembered the cake he had eaten in Xitang one day. He wanted to eat it very much and asked the little eunuch to get it, but how to write this imperial edict? Fortunately, the little eunuch went with him, so Tang decided to let the little eunuch preach the imperial edict.
The little eunuch came to Xitang, found his family and repeatedly shouted, "Take the imperial edict." Who knew the door was left unlocked and no one answered? When I asked my neighbors, I realized that the young man had been in Beijing for several months in order to catch the exam.
After listening to the little eunuch's recital, Tang thought, there are thousands of candidates in Beijing, where can I find the young man who makes cakes? He had a brainwave and came up with a special examination question-making cakes. This time, the candidates are all messed up. Those sons and brothers can only eat cakes, but can't make cakes. Even those poor scholars didn't expect such a problem. So some people paid a lot of money to ask the pastry chef for help, and some people went to find books to make cakes, but they didn't like the emperor. Only the young man in Xitang succeeded in making delicious cakes. Tang tasted it, was very satisfied and happy, so he appointed this young man as the champion.
Among the cake makers, they won the first prize, which was told as a much-told story. The cake made by the champion is naturally called the "champion cake".
