According to historical records, emperors in ancient times often held activities to worship the moon, and the date was set on August 15 of the lunar calendar. Because it is half of Sanqiu, it is called Mid-Autumn Festival.
The word "Mid-Autumn Festival" originated from Zhou Li, and the Book of Rites recorded that "the son of heaven is in the spring and the sun is shining, and the autumn is the moon. Asahi is facing the DPRK, and the evening is in the evening. " Therefore, in the Zhou Dynasty, there was already a ritual activity that the son of heaven went to Yue Bai on the Mid-Autumn Festival. The Mid-Autumn Festival began in the early years of the Tang Dynasty and prevailed in the Song Dynasty. By the Ming and Qing Dynasties, it had become one of the traditional festivals in China with the same reputation as the Spring Festival.

Second, the original text
The jade star Shanshan got off the moon wheel and picked up the dew in front of the temple.
So far, there is no such thing as heaven, but Chang 'e should throw it at people.
Iii. Translation
The petals of osmanthus falling one after another are scattered from under the moon like jade beads. I went to the front of the main hall and picked them up. I saw that there were just a few dew flowers on the petals.
Up to now, I don't know what happened in the sky. I think these sweet-scented osmanthus flowers with dew should be thrown to us by Chang 'e in Guanghan Palace.
