1, the origin of the Double Ninth Festival can be traced back to ancient times. According to legend, Chongyang is the day of enlightenment in Yuan Di. There are existing written records about the activities of the Double Ninth Festival, which can be found in Lu Chunqiu Qiu Ji Ji: "In September, the family is ordered to slaughter, and the cultivation is prepared for harvest, and five essentials are introduced. The Tibetan emperor's book is collected in the holy warehouse, and it is only respectful. It's the day, great emperor, and I'll taste the sacrifice and tell the son of heaven. "

2. Meaning: Taizai must be respectfully and solemnly ordered to set up an account book to register the grain after all the crops are harvested, and hide the grain harvested in the land of the Son of Heaven in a barn dedicated to storing the grain for sacrifice to the gods.

3. It can be seen that there was an activity of offering sacrifices to God and ancestors during the autumn harvest in September to thank them for their kindness. This is the primitive form of the ancient Double Ninth Festival as a sacrificial activity.
