At first, the festival of "Sacrificing the Moon" was held on the day of "Autumn Equinox" in the 24th solar term of the Ganzhi calendar, and later it was transferred to August 15th in the summer calendar (lunar calendar). In some places, the Mid-Autumn Festival was set on August 16th in the summer calendar. Since ancient times, Mid-Autumn Festival has had folk customs such as offering sacrifices to the moon, enjoying the moon, eating moon cakes, playing with lanterns, enjoying osmanthus flowers, drinking osmanthus wine, etc., which have spread to this day and lasted for a long time.
