August 15th is right in the middle of autumn, so it is called the Mid-Autumn Festival. The ancient Chinese calendar called August, which is in the middle of autumn, "Zhongqiu", so the Mid-Autumn Festival is also called "Zhongqiu Festival".

According to historical records, the term "Mid-Autumn Festival" first appeared in the book "Zhou Rites". In the Wei and Jin Dynasties, there was a record of "ordering the minister to suppress the cattle confusion, and on the Mid-Autumn Festival night, the left and right people were incognito and flooded the river". It was not until the early years of the Tang Dynasty that the Mid-Autumn Festival became a fixed festival. "Book of Tang·Taizong Ji" records the "Mid-Autumn Festival on August 15th". The popularity of the Mid-Autumn Festival began in the Song Dynasty. By the Ming and Qing Dynasties, it had become as famous as New Year's Day and became one of the major festivals in our country. This is also the second largest traditional festival in our country after the Spring Festival.

"West Lake Tour Notes" says: "The fifteenth day of August is called the Mid-Autumn Festival, and people send mooncakes to each other to symbolize reunion." "A Brief Introduction to the Scenery of the Imperial Capital" also says: "When worshiping the moon on the 15th day of the eighth lunar month, the cakes will be round, the melons will be broken into pieces, and the petals will be carved like lotus flowers. ... Those who have a wife who has returned to peace will return to her husband's house on this day, which is called reunion. On the night of the Mid-Autumn Festival, most areas in my country still have the custom of baking "reunion", which is a small cake that symbolizes reunion and is similar to a moon cake. The cake is filled with sugar, sesame, osmanthus and vegetables, and the moon, osmanthus and rabbit are pressed on the outside. After worshiping the moon, the elders of the family will cut the cake into pieces according to the number of people, and leave one for each person if someone is not at home, which represents the origin of the Mid-Autumn Festival. Another saying is that the 15th day of the eighth lunar month happens to be the time when rice is ripe, and every family worships the God of the Earth. The Mid-Autumn Festival may be a legacy of the autumn harvest.
