August 15th of the lunar calendar is the traditional Mid-Autumn Festival. This is the middle of autumn, so it is called Mid-Autumn Festival. In China's lunar calendar, a year is divided into four seasons, and each season is divided into three parts: Meng, Zhong and Ji, so Mid-Autumn Festival is also called Mid-Autumn Festival. The moon on August 15th is rounder and brighter than the full moons in other months, so it is also called "Moon Night" and "August Festival".

On this night, people look up at the bright moon in the sky like jade, and naturally look forward to family reunion. Wanderers who are far away from home also take this opportunity to pin their thoughts on their hometown and relatives. Therefore, Mid-Autumn Festival is also called "Reunion Festival".

In ancient times, our people had the custom of "autumn dusk and evening moon". The evening moon is to worship the moon god. In the Zhou dynasty, every mid-autumn night was held to welcome the cold and offer sacrifices to the moon. Set up a big incense table, and put moon cakes, watermelons, apples, red dates, plums, grapes and other sacrifices, among which moon cakes and watermelons are absolutely indispensable. Watermelon has to be cut into lotus shapes.

Under the moon, put the moon statue in the direction of the moon, and the red candle burns high. The whole family worships the moon in turn, and then the housewife cuts up the reunion moon cake. Cut the people in advance to calculate the number of people in the whole family, at home and in the field, all together, can not cut more or less, the size should be the same.
