The moon festival is an important festival in Chinese culture:

"Moon Cake Festival: A Mid-Autumn Festival (Chung Chiu), the third major festival of the Chinese calendar, is celebrated on the 15th day of the eighth month. This festival corresponds to harvest festival s observed by Western cultures (in Hong Kong, it is held in conjunction with the annual Lantern Festival).

Contrary to what most people believe, this festival probably has less to do with harvest festivities than with the philosophically minded chinese of old. The union of man's spirit with nature in order to achieve perfect harmony was the fundamental canon of Taoism, so much so that contemplation of nature was a way of life."
