Mid Autumn Festival, also known as Moon Festival, moon birthday, moon Eve, autumn festival, Mid Autumn Festival, moon worship Festival, moon mother's day, Moon Festival and reunion festival, is a traditional festival among Chinese people. The Mid Autumn Festival originated from the worship of celestial phenomena and evolved from the worship of the moon on autumn Eve in ancient times. At first, the festival of "sacrificing the moon" was held on the 24 solar terms "autumnal equinox" of the Ganzhi calendar. Later, it was adjusted to August 15 of the summer calendar (lunar calendar). In some places, the Mid Autumn Festival was set on August 16 of the summer calendar. Since ancient times, the Mid Autumn Festival has folk customs such as sacrificing the moon, appreciating the moon, eating moon cakes, playing lanterns, appreciating osmanthus, drinking osmanthus wine and so on.
