The Queen Mother of the West rewarded two immortal elixirs, which were kept by Chang 'e, the wife of Yi. Meng, the disciple of Yi, grabbed the elixirs on August 15th, and Chang 'e swallowed them all to protect them. She immediately rose to the moon palace but couldn't get down. Because she missed Chang 'e, she made food like the moon on August 15th and waited for Chang 'e's return. This is the Mid-Autumn Festival.

After the Goddess Chang'e flying to the moon Hou Yi became emperor, he became a tyrant by indulging in debauchery and killing people at will. He wanted to live forever and went to Kunlun Mountain to steal the immortal medicine of the Queen Mother. His wife Chang 'e was afraid that he would live forever and the people would suffer, so she stole the immortal medicine and ate it, so she flew lightly to the Moon Palace herself.

According to legend, the osmanthus tree in front of the Guanghan Palace on the moon grows luxuriantly, with a height of more than 500 feet. There is a man who often cuts it down, but every time he cuts it down, the cut place is closed immediately. For thousands of years, it has been like this. It is said that this tree-chopping man, named WU GANG, once followed the Immortal in monasticism, but when he made a mistake, the Immortal relegated him to the Moon Palace, and did this futile chore every day to show his punishment.

Legend has it that three immortals turned into three poor old people, begging for food from the fox, the monkey and the rabbit. Both the fox and the monkey had food to help, but the rabbit was helpless. Later, the rabbit said, "You can eat my meat!" He jumped into the fire and cooked himself. The fairy was greatly moved and sent the rabbit to the moon palace to become a jade rabbit. Accompany Chang 'e, as a panacea for her descent.
