Celebration of Mid-autumn festival has a long history. In ancient times, the emperors had the tradition of worshiping the Sun in spring, and the Moon in autumn. The word "Mid-Autumn" first appeared in the famous ancient book "Zhou Li" (The Zhou Rituals, a book telling the rituals in the Zhou Dynasty). However, it was not until the early Tang Dynasty that the day was officially celebrated as a traditional festival. It became a established festival during the Song Dynasty, and has become as popular as the Spring Festival since the Ming and Qing Dynasties. Celebrations have continued ever since and more customs for marking this occasion have been formed.

There are several explanations on when and where the festival began and some of the most convincing versions are as follows:

Version One: Nanjing and Mid-autumn Festival

A much-told story about the beginning of the Mid-autumn Festival celebration comes from Niuzhu (a place in ancient Nanjing). As early as 1,600 years ago, Nanjing which was called Jianye served as capital of the Eastern Jin Dynasty. On a Mid-autumn night when Xie Shangyue, the governor of Niuzhu, was boating on a river he met Yuan Hong, a poor, frustrated but gifted scholar who had to earn his living by renting boats. Admiring his ability, Xie made friend with him and Yuan had a rise to fame with the help of Xie. Later on, having heard of the story, many refined scholars from all over the country followed suit to boat in the river, climb up the towers, and watch the moon. Famous poets like Li Bai and Ou Yangzhan were all touched by the story, and then wrote numbers of poems about it. Because of this, the tradition of watching the moon on Mid-Autumn Festival gradually came into being.

Version Two: Season and Climate

The Mid-Autumn day is the very moment of rice maturity. And at that day farmers will worship the local God of land, whose birthday is exactly on that day. Mid-Autumn day is possibly an old tradition of telling the coming of autumn. In terms of the seasons in a year, the Mid-Autumn day can be named as "Harvest Day", when the crops sowed in the spring can be reaped. Since ancient times, people would drink, dance, and sing on that day, celebrating the harvest. This scene can be found in the Books of Odes (the earliest collection of poems in ancient China).
