Legend has it that Chang 'e was originally the wife of Hou Yi. After Houyi shot nine suns, the Queen Mother of the West gave her the elixir of life, but Houyi refused to take it, so she gave it to Chang 'e for safekeeping. Meng Peng, a disciple of Hou Yi, coveted the fairy medicine and forced Chang 'e to hand it over. Chang 'e swallowed it in despair and flew into the sky.

It was August 15th, and the moon was big and bright. Because of giving up Houyi, Chang 'e stopped on the moon closest to the earth and lived in Guanghan Palace for a long time. After returning home, Hou Yi was heartbroken, so he hosted a banquet on August 15th every year to meet Chang 'e.

The origin of moon cakes:

Ancient moon cakes were eaten as sacrifices in the Mid-Autumn Festival. It is said that the custom of eating moon cakes in Mid-Autumn Festival began in the Tang Dynasty. It was popular in the court in the Northern Song Dynasty and later spread among the people. At that time, it was commonly known as "small cake" and "moon group". In the Ming dynasty, it became a common dietary custom of the whole people. Mooncakes have been integrated into the local dietary customs and are deeply loved by people all over China.
