Origin of Mid-Autumn Festival II: 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 out nine suns, and then God gave him a medicine to become immortal. He was reluctant to leave his wife Chang 'e, so he gave it to Chang 'e for safekeeping. On August 15th, Chang 'e took the fairy medicine and 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, from generation to generation, it evolved into a festival. Because this day is the Mid-Autumn Festival, it is called the Mid-Autumn Festival.
