Extension:
Mid-Autumn Festival has a long history. Like other traditional festivals, it develops slowly. The ancient emperors had a system of offering sacrifices to the sun in spring and the moon in autumn. As early as in Zhou Li, the word "Mid-Autumn Festival" was recorded. Later, aristocratic scholars followed suit. During the Mid-Autumn Festival, they watch and worship the bright and round moon in the sky to express their feelings. This custom spread to the people and formed a traditional activity. Until the Tang Dynasty, people paid more attention to this custom of offering sacrifices to the moon, and the Mid-Autumn Festival became a fixed festival. Emperor Taizong recorded the Mid-Autumn Festival on August 15, which was very popular in the Song Dynasty.
The legend of Mid-Autumn Festival is very rich, and fairy tales such as the Goddess Chang'e flying to the moon, Wu Gang cutting Guangxi and Jade Rabbit smashing medicine are widely circulated.
