Which book does the text of traditional festivals come from?

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 "called Shangshu Niu, drifting across the river in the Mid-Autumn Festival in disguise". It was not until the early years of the Tang Dynasty that the Mid-Autumn Festival became a fixed festival. Emperor Taizong's book records "Mid-Autumn Festival on August 15th". The popularity of Mid-Autumn Festival began.

According to the China calendar, the eighth month of the lunar calendar is in the middle of autumn, which is the second month of autumn, so it is called "Mid-Autumn Festival", and August 15th is among them, 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 the Mid-Autumn Festival are all around the moon, it is also commonly known as the "Moon Festival" and "Moon Festival". Mid-Autumn Festival is also called "Reunion Festival" because the full moon symbolizes reunion. 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. "Notes on Traveling to the West Lake" says: "August 15th is the Mid-Autumn Festival, and people send moon cakes to show their reunion". In A Brief Introduction to the Scenery of the Imperial Capital, it is also said that "August 15th is the festival of the Moon". In most parts of our country, there is a custom of "reunion", that is, it is branded with cakes symbolizing reunion and similar to moon cakes. The cakes contain sugar, sesame, osmanthus and vegetables, and the moon, osmanthus trees and rabbits are pressed on the outside. After the Mid-Autumn Festival, the elderly at home will cut the cake into pieces according to the number of people, one for each person, and if someone is not at home, they will also leave one for them to show their 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 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.
