The custom of enjoying the moon comes from offering sacrifices to the moon, and serious sacrifices have become relaxed pleasures. Folk Mid-Autumn Festival activities began in Wei and Jin Dynasties, but they did not become a habit. In the Tang Dynasty, it was quite popular to enjoy and play with the moon in the Mid-Autumn Festival, and many poets wrote poems about the moon in their masterpieces. By the time of the Song Dynasty, a Mid-Autumn Festival centered on the activities of appreciating the moon was formed and officially designated as the Mid-Autumn Festival. Different from the Tang people, the Song people appreciate the moon more because they feel hurt by things, and often use rain or shine as a metaphor for human affairs. Even on the Mid-Autumn night, the clear light of the bright moon can't hide the sadness of the Song people. But for the Song people, the Mid-Autumn Festival has another form, that is, it is a secular and joyful festival: "Before the Mid-Autumn Festival, all the shops sold new wine, and your family decorated pavilions, and the people competed for the restaurant to play with the moon, and the songs were heard thousands of miles away, and the play continued until dawn" (Dream of China in Tokyo). The Mid-Autumn Festival in the Song Dynasty is a sleepless night. The night market is open all night, and there are endless tourists playing with the moon.

Eat moon cakes to show "reunion" Moon cakes, also known as Hu cakes, palace cakes, moon groups, harvest cakes, reunion cakes, etc., are offerings to worship the moon god in ancient Mid-Autumn Festival. According to legend, in ancient China, emperors had a ritual system of offering sacrifices to the sun in spring and the moon in autumn. In the folk, every Mid-Autumn Festival in August, there are also customs about Yue Bai or offering sacrifices to the moon. The famous proverb "The moon is full on August 15th, and the moon cakes in Mid-Autumn Festival are sweet and fragrant" tells the custom of urban and rural people eating moon cakes on Mid-Autumn Festival night. At first, mooncakes were used as sacrifices to the moon god. Later, people gradually regarded the Mid-Autumn Festival as a symbol of family reunion, and gradually, mooncakes became a necessary gift for festivals.
