At first, the festival of "offering sacrifices to the moon" was held on the day of "Autumn Equinox" in the 24 solar terms of the Millennium, and later it was moved to August 15th of the lunar calendar. In some places, the Mid-Autumn Festival is set on August 16th of the lunar 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 and drinking osmanthus wine.
