Lunar August 15th is China’s traditional Mid-Autumn Festival. It is called Mid-Autumn, because it is exactly in the middle of autumn. On this night, the moon is the fullest and brightest of the year, so it is also called “Yuexi” or “Bayuejie”. When people look at the round moon on the August 15th, they look forward to family reunion. People who are far away from their home also express homesickness to their families. So Mid-Autumn Festival also is called “Union Festival”.
