In ancient times, our people had the custom of setting the moon at the end of autumn.

 In other words, they worshipped the moon god. In the Zhou Dynasty, every mid-autumn 

night, there was a ceremony to welcome the cold and offer sacrifices to the moon. 

A large incense burner was set up, and mooncakes, watermelons, apples, jujubes, plums, 

grapes and other offerings were placed on the table, of which mooncakes and watermelons 

were absolutely indispensable. The watermelon should also be cut in the shape of a lotus 

flower. Under the moon, the statue of the moon god is placed in the direction of the moon,

 red candles are lit high, and the whole family pays homage to the moon in turn, and then 

the housewife cuts the mooncakes for reunion. The person who cuts the mooncake counts 

the number of people in the family in advance, those who are at home and those who are

 out of town, and all of them must be counted together, and they must not cut too much 

or too little, and the size must be the same.
