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. The Mid-Autumn Festival originated from the worship of celestial phenomena and evolved from the worship of the moon in autumn and evening in ancient times. Since ancient times, Mid-Autumn Festival has had folk customs such as offering sacrifices to the moon, enjoying the moon, eating moon cakes, watching lanterns, enjoying osmanthus flowers, drinking osmanthus wine, etc., which have spread to this day and lasted for a long time.

The Mid-Autumn Festival originated in ancient times, popularized in the Han Dynasty and shaped in the Tang Dynasty. Mid-Autumn Festival is a synthesis of seasonal customs in autumn, and most of the festival customs contained in it have ancient origins. As one of the important customs of folk festivals, offering sacrifices to the moon has gradually evolved into activities such as appreciating and praising the moon. The Mid-Autumn Festival is a colorful and precious cultural heritage, with the full moon as a sign of people's reunion, as the sustenance of missing their hometown and their loved ones, and hoping for a bumper harvest and happiness. ?

At first, the festival of "Sacrificing the Moon" was held on the day of "Autumn Equinox" in the 24th solar term of the Ganzhi calendar, and it was later transferred to August 15th of the lunar calendar. Mid-Autumn Festival, Spring Festival, Tomb-Sweeping Day and Dragon Boat Festival are also called the four traditional festivals in China. Influenced by Chinese culture, Mid-Autumn Festival is also a traditional festival for overseas Chinese in some countries in East and Southeast Asia, especially local Chinese. ?
