What is the origin of Mid-Autumn Festival?

Mid-Autumn Festival, also known as Moon Festival, Moonlight Birthday, Moon Festival, Autumn Festival, Mid-Autumn Festival, Moon Festival, Moon Festival and Reunion Festival, is a traditional folk festival in China. [1] The Mid-Autumn Festival originated from the worship of celestial phenomena and evolved from the worship of the autumn moon in ancient times. At first, the festival of "Sacrificing the Moon" was held on the "autumnal equinox" of the 24 solar terms in the Ganzhi calendar, and later it was moved to August 15 in the summer calendar (lunar calendar). In some places, the Mid-Autumn Festival is set on August 16 in the summer calendar.

The Mid-Autumn Festival originated in ancient times, popularized in the Han Dynasty, shaped in the early Tang Dynasty and prevailed after the Song Dynasty. Mid-Autumn Festival is a synthesis of autumn seasonal customs, most of which have ancient origins. The Mid-Autumn Festival is a colorful and precious cultural heritage. The full moon is a symbol of people's reunion, a sustenance for missing their hometown and relatives, and hopes for a bumper harvest and happiness.
