Chang 'e boarded the Moon Palace. According to ancient books such as Huai Nan Zi in the Western Han Dynasty, it was because she ate the elixir that her husband Yi asked for from the West Fifth Mother that she flew into the Moon Palace and turned into a toad. In the eastern Han Dynasty, Gao You annotated Huai Nan Zi, saying that Chang 'e was the wife of Da Yi. It is said that Da Yi's wife's name is Heng 'e, because people in the Han Dynasty avoided the taboo of the then emperor Liu Heng, and later her name was changed to Chang 'e (Chang E).
Extended information Chang 'e is a moon fairy in China mythology. In Shan Hai Jing, the medieval celestial emperor, the daughter of Di Jun and the wife of Hou Yi (Da Yi), was called Heng E (Heng E) because of her extraordinary beauty, but she was renamed E in order to avoid the taboo of Chinese Emperor Liu Heng in the Western Han Dynasty, and was also called Chang E. There are also people who call it Chun Hu.
In the myth, Da Yi lived in the Guanghan Palace above the moon because he took the elixir of immortality from the Queen Mother of the West.
Before the Eastern Han Dynasty, there was no data to indicate that Chang 'e and Yi were husband and wife, and Gui Zang explained that they might be husband and wife by comparing the divinatory images. It was not until Gao You annotated Huai Nan Zi that Chang 'e was the wife of Hou Yi. In some folklore, Chang 'e is merged with the moon god Taiyin Xingjun in Taoist mythology, honorably called the Moon Palace Huang Huasu Yao Yuan Jing Sheng Hou Taiyin Yuanjun, or the Moon Palace Taiyin Huangjun filial piety and Ming Wang, as a female figure.
