What is the origin of Mid-Autumn Festival?

The origin of Mid-Autumn Festival: Mid-Autumn Festival evolved slowly from the ancient Moon Festival. The ancient calendar divided each season into three months, namely, Meng Yue, Mid-Autumn Festival and Yue Ji. August in the lunar calendar is the second month of autumn, so it is called "Mid-Autumn Festival", while August 15th in the lunar calendar is just half of autumn, so it is 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 second origin of Mid-Autumn Festival: Mid-Autumn Festival evolved from the story of the Goddess Chang'e flying to the moon. This story is the most widely circulated. 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 took the fairy medicine 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.

The origin of Mid-Autumn Festival: Mid-Autumn Festival evolved from offering sacrifices to land gods. In farming society, crops are very important to farmers, so people often sacrifice land. During the autumn harvest, farmers will make sacrifices to the land gods. The fifteenth day of the eighth lunar month is just the harvest time of crops, so it gradually evolved into the Mid-Autumn Festival.
