Mid-Autumn Festival is a traditional festival in China. According to historical records, the word "Mid-Autumn Festival" first appeared in the book Zhou Li. In the Wei and Jin Dynasties, there was a record of "telling Shangshu Town about the cow's confusion, crossing the river in mid-autumn, and traveling incognito around". It was not until the early years of the Tang Dynasty that the Mid-Autumn Festival became a fixed festival. The Book of Emperor Taizong recorded the Mid-Autumn Festival on August 15. The prevalence of Mid-Autumn Festival began in the Song Dynasty, and it became one of the major festivals in China in the Ming and Qing Dynasties. This is also the second largest traditional festival in China after the Spring Festival.

According to the China calendar, the eighth month of the lunar calendar is in the middle of autumn, and the second month of autumn is called "Mid-Autumn Festival", and August 15th is in the middle of it, so it is called "Mid-Autumn Festival". Mid-Autumn Festival has many nicknames: it is called "August Festival" and "August and a half" because it falls on August 15th; Because the main activities of Mid-Autumn Festival are all around the moon, it is also commonly known as "Moon Festival" and "Moonlit Night". The full moon in Mid-Autumn Festival symbolizes reunion, so it is also called "Reunion Festival". In the Tang Dynasty, the Mid-Autumn Festival was also called "correcting the moon". The record of "Reunion Festival" was first seen in the Ming Dynasty. "Journey to the West Lake" says: "August 15th is the Mid-Autumn Festival, and people send moon cakes to show their reunion". "A Brief Introduction to the Scenery of the Imperial Capital" also said: "On August 15th, the moon was sacrificed, the cakes were round, the melons were wrongly divided, and the petals were carved with lotus flowers. ..... If a wife goes back to Ning, she will return to her husband's family one day. This is called "Reunion Festival". On the night of Mid-Autumn Festival, there is a custom of "reunion" in most parts of our country, that is, flipping a small cake symbolizing reunion, which is similar to a moon cake. The cake contains sugar, sesame, sweet-scented osmanthus and vegetables, and the moon, sweet-scented osmanthus tree and rabbit are pressed outside. After the Mid-Autumn Festival, the elders at home will divide the cake into pieces according to the number of people, and each person will have one. If someone is not at home, leave one for them to show family reunion.

During the Mid-Autumn Festival, there are fewer clouds and more fog, and the moonlight is bright and bright. In addition to a series of activities such as enjoying the moon, offering sacrifices to the moon, eating moon cakes and wishing for reunion, there are activities such as dancing grass dragons and building stupas in some places. In addition to moon cakes, all kinds of seasonal fresh fruits and dried fruits are also delicious in the Mid-Autumn Festival.

Another explanation for the origin of Mid-Autumn Festival is that the 15th day of the eighth lunar month happens to be the time when rice is ripe, and all families worship the land god. Mid-Autumn Festival may be the legacy of Qiubao.
