The origin of Mid-Autumn Festival. August 15th of the lunar calendar is the Mid-Autumn Festival in China. Because this day is half of autumn, it is called Mid-Autumn Festival, which is commonly known as August Festival among the people. This is the origin of Mid-Autumn Festival.

As early as the Han Dynasty, there was already a Mid-Autumn Festival in China. But not on August 15th, but on that day in beginning of autumn. On this day, princes and nobles went out hunting and brought their prey to the temple. In the Tang Dynasty, there were no records of Mid-Autumn Festival stories in various books. In the Song Dynasty, there were more records about the Mid-Autumn Festival. At that time, in the Mid-Autumn Festival, "the family complained about getting married, and the people fought for restaurants", and even the poor citizens "undressed and drank, barely welcoming guests". Since then, the Mid-Autumn Festival has become the second largest festival in China after the Spring Festival.

Mid-Autumn Festival is a traditional folk festival of Han nationality. Besides Han nationality, Hui, Su, Zhuang, Buyi and North Korea also celebrate this festival. It is related to the ritual system of offering sacrifices to the moon in autumn in ancient China. The Mid-Autumn Festival is held on the 15th day of the eighth lunar month, just in the middle of Sanqiu, hence its name.
