Mid-Autumn Festival evolved from the worship of the moon in ancient times. The ancient calendar divided each season into three months, namely, Meng Yue, Mid-Autumn Festival and Yue Ji. August of the lunar calendar happens to be the second month of autumn, which is called "Mid-Autumn Festival", and August 15th of the lunar calendar happens to be half a day of autumn, so it is also called "Mid-Autumn Festival". At first, this day was designated as a festival for ancient emperors to sacrifice to the moon, and later it gradually evolved into the Mid-Autumn Festival.

The Mid-Autumn Festival originated from the story of the Goddess Chang'e flying to the moon. Hou Yi shot nine suns, and then God gave him an immortal medicine. He could not bear to part with his wife Chang 'e, so he gave it to Chang 'e for safekeeping.

On August 15, Chang 'e ate the fairy medicine, and then she went to the moon. Hou Yi misses Chang 'e, so every year on this day, Chang 'e's favorite food will be placed in the garden, hoping that she can come back for reunion. After that, every year, generation after generation, it evolved into a festival. Because this day is the Mid-Autumn Festival, it is called the Mid-Autumn Festival.
