The origin of festivals is closely related to the calendar, and the origin of Mid-Autumn Festival is no exception. Mid-Autumn Festival is also called "Mid-Autumn Festival" because August 15th is the second month of three months in autumn. Autumn is the season when crops are ripe. In ancient times, there were "autumn clubs" all over the country, which were sacrifices to thank the gods such as land, also known as "autumn newspaper" The "Autumn Festival" in ancient and medieval times didn't have to be on August 15th. The date of Mid-Autumn Festival should also be related to people's custom of offering sacrifices and enjoying the moon. There was a "late moon" in the pre-Qin period, which was the royal etiquette of offering sacrifices to the moon at the autumn equinox. The moon in Mid-Autumn Festival is the roundest, brightest and most pleasant. On this day, later generations combined "Autumn Festival" with festivals and customs such as offering sacrifices to the moon, Yue Bai, enjoying the moon, watching the tide, enjoying laurels and feeding moon cakes, which gradually gave new meanings to this festival, such as reunion. Since then, a meaningful festival has been formed.

It is thought-provoking to change from the "Autumn Festival" which is purely a farming ceremony to the "Reunion Festival" which symbolizes family reunion and happiness. "Autumn party" and "reunion" naturally have some common pursuits from the psychological level. Praying for a bumper harvest or holding a sacrificial ceremony to reward the gods of heaven and earth is undoubtedly praying for material wealth and a rich and happy life; And looking forward to reunion is not the hope for a happy and happy life? But the difference between them is not difficult to analyze. The former seems to pay more attention to material wealth, while the latter seems to pay special attention to the pursuit of family and interpersonal harmony, so it pays more attention to spirit. But what does the formation of the word "reunion" in Mid-Autumn Festival mean? It shows that China people's pursuit of family affection, family harmony and interpersonal harmony exceeds the pursuit of material things. On the other hand, the existence of the custom of Mid-Autumn Festival has cultivated China people's spirit of attaching importance to family, affection and harmonious interpersonal relationship.

The Mid-Autumn Festival is rooted in the extremely deep traditional ethical and cultural soil.
