今天是中秋节，这个节日是在农历的8月15满月之时。庆祝中秋节又很悠久的历史
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).
在古代，皇帝春特别崇拜春天的太阳，秋天的月亮。中秋二字第一次出现在《周礼》这本书中。（周礼是一本讲述周代故事的书）
However, it was not until the early Tang Dynasty that the day was officially celebrated as a traditional festival. It became an established festival during the Song Dynasty, and has become as popular as the Spring Festival since the Ming and Qing Dynasties. Celebrations has continued ever since and more customs for marking this occasion have been formed.
然而，在早唐开始庆祝这个节日，直到宋代之后，中秋节才被立为传统的节日。在明清时代变得越发受人欢迎。这些庆祝的传统在越老越多的习惯累积而得以延续。
