At the beginning of the Tang Dynasty, in order to pacify the foreign invasion in the north, Tang Gaozu Li Yuan appointed the then famous general Li Jing as the commander-in-chief of the northern expedition, and fought back against the Turks and finally won.

The day of Li Jing's triumph happened to be August 15, and it happened that Turpan people presented cakes to Li Yuan that night. Li Yuan was very happy to see Zhu Jie cake, and blurted out that "Hu cake should be invited to toad".

The second legend: eating moon cakes and "killing Tartars"

At the end of Yuan Dynasty, natural and man-made disasters occurred repeatedly, and the people were miserable. The Mongols' rule over the Han people in the Central Plains was also more severe. These enslavement policies aroused the dissatisfaction of the Han people, and the civil resistance was strong. Uprising was brewing everywhere, and an agreement was made to "kill the Tartars" and overthrow the Yuan regime.

At that time, public gathering was not feasible. In order to convey the signal of unified action and ensure secrecy, Zhu Yuanzhang in the south, later Ming Taizu, chose the opportunity of eating moon cakes on August 15th, and wrapped the note with the signal of uprising in the moon cakes. Through this way of transmission, a huge uprising force was formed.

Extended data:

Moon cakes are also called reunion cakes, because they are round in shape, which means that family happiness has become a symbol of family reunion. This beautiful meaning has been handed down from ancient times and is still very applicable today.

The term "moon cake" first appeared in the early Tang Dynasty. At that time, the Tang Dynasty made Chang 'an its capital, and its national strength was strong. The spectacular sight of all countries worshipping was not just talk, so in an autumn, the Tubo caravan came to Chang 'an.

They gave many gifts to Tang Gaozu, and one of these gifts was called round cakes. On the night of Mid-Autumn Festival, Tang Gaozu and his family ate round cakes while enjoying the moon, and changed the name of round cakes to moon cakes, which is the earliest record of the term moon cakes.
