It is said that in ancient China, the emperor had the ritual of sacrificing to the sun in spring and sacrificing to the moon in autumn. In folk culture, every August on the lunar calendar during the Mid-Autumn Festival, there are customs of worshiping or sacrificing to the moon. The proverb "the moon is round on August fifteenth, and the moon cakes of the Mid-Autumn Festival are fragrant and sweet" reveals the custom of urban and rural people eating moon cakes on the night of the Mid-Autumn Festival. Moon cakes were originally used as offerings to sacrifice to the moon goddess, and later people gradually associated admiring the moon on the Mid-Autumn Festival with tasting moon cakes as a symbol of family reunion, and slowly moon cakes also became festival gifts.
