Mid-Autumn Festival, also known as Moon Festival, Autumn Festival, Mid-Autumn Festival, August Festival, Moon Chasing Festival, Mid-Autumn Festival, Daughter's Day or Reunion Festival, is a traditional cultural festival popular among many ethnic groups in China. It falls on the 15th day of the eighth lunar month. It is named because its value is only half that of Sanqiu. It is said that the moon is closest to the earth this night, and the moon is the biggest and brightest, so there has been a custom of drinking and enjoying the moon since ancient times.

The daughter-in-law who goes back to her parents' house will go back and forth to express her happiness and good luck. In some places, such as Ningbo, Taizhou and Zhoushan, the Mid-Autumn Festival is scheduled for August 16, which is related to changing it to "Lantern Festival on the 14th day of the first month and Mid-Autumn Festival on the 16th of August" in order to prevent attacks by officers and men of the Yuan Dynasty and Zhu. Besides, in Hongkong, after the Mid-Autumn Festival, we will hold another carnival in Izayoi, called "Chasing the Moon".
