Moon cakes are one of the traditional cakes in China with a long history. People eat moon cakes in the Mid-Autumn Festival. Moon cakes are round and shared by the whole family, symbolizing reunion and harmony. Ancient moon cakes were eaten as sacrifices in the Mid-Autumn Festival. It is said that the custom of eating moon cakes in Mid-Autumn Festival began in the Tang Dynasty. It was popular in the court in the Northern Song Dynasty and later spread among the people. At that time, it was commonly known as "small cake" and "moon group".

Mooncakes have been integrated into local dietary customs and developed into Cantonese-style mooncakes, Beijing-style mooncakes, Suzhou-style mooncakes, Chaozhou-style mooncakes and Yunnan-style mooncakes, which are deeply loved by people all over the country.

Speaking of it, the same is true of the moon cake industry. "Beijing is in the south of Guangzhou and the east of Jiangsu, Anhui and Yunnan", and Beijing flavor is firmly at the top of the list. Specifically, these four schools are: Beijing-style moon cakes, Cantonese-style moon cakes, Soviet-style moon cakes and Yunnan-style moon cakes. Among the mooncakes with Beijing flavor, the largest sect in Wulin, "Wuren" has the highest status, the greatest reputation and the longest history.
