The Mid-Autumn Festival, also known as the Moon Festival, Moonlight Festival, Moon Festival, Autumn Festival, Mid-Autumn Festival, Moon Festival, Moon Festival, and Reunion Festival, is a traditional Chinese folk festival. The Mid-Autumn Festival originated from the worship of celestial phenomena and evolved from the worship of the moon on the autumn eve in ancient times. Since ancient times, the Mid-Autumn Festival has folk customs such as offering sacrifices to the moon, appreciating the moon, eating moon cakes, watching lanterns, appreciating osmanthus flowers, and drinking osmanthus wine, which have been handed down for a long time.

The Mid-Autumn Festival originated in ancient times, was popularized in the Han Dynasty and finalized in the Tang Dynasty. The Mid-Autumn Festival is a synthesis of autumn seasonal customs. Most of its festival customs 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 the moon and praising the moon. The Mid-Autumn Festival symbolizes the reunion of people with the full moon. It is to express the yearning for home and relatives, and to pray for a bumper harvest and happiness. It has become a colorful and precious cultural heritage.

At first, the festival period of "Festival of Sacrificing the Moon" was on the day of the twenty-fourth solar term "Autumn Equinox" in the Ganzhi calendar, and then it was adjusted to the fifteenth day of August in the lunar calendar. The Mid-Autumn Festival, together with the Spring Festival, the Qingming Festival and the Dragon Boat Festival, is known as the four traditional festivals in China. Influenced by Chinese culture, the Mid-Autumn Festival is also a traditional festival for some countries in East Asia and Southeast Asia, especially local Chinese and overseas Chinese.

On May 20, 2006, the State Council listed it in the first batch of national intangible cultural heritage list. The Mid-Autumn Festival has been listed as a national legal holiday since 2008.
