Mid-Autumn Festival, also known as Moon Festival, Autumn Festival, Mid-Autumn Festival, Moonlight Festival, Moon Eve, Moon Worship Festival, Moon Mother Festival, Moon Festival, Reunion Festival, etc., is a traditional Chinese folk festival.

The Mid-Autumn Festival originated from the worship of celestial phenomena and evolved from worshiping the moon on the autumn eve of ancient times.

Originally, the "Moon Festival" was the "autumn equinox" among the 24 solar terms, but later it was adjusted to the 15th day of the eighth lunar month, and in some places it was the 16th day of the eighth lunar month.
