Chang 'e, the daughter of Di Ku (Di Jun), one of the three emperors and five emperors in ancient times, and the wife of Hou Yi (Da Yi), was called Heng E because of her extraordinary beauty. She was renamed Chang 'e and Chang E in the Western Han Dynasty to avoid the taboo of Liu Heng, the Chinese emperor.
It is said that Chang 'e and Hou Yi initiated monogamy. Later generations interpreted the story of the Goddess Chang'e flying to the moon in memory of them, and many folk legends and poems and songs were circulated. Before the Eastern Han Dynasty, there was no data showing that Chang 'e and Yi were husband and wife, and it was not until Gao You annotated Huai Nan Zi that Chang 'e was the wife of Hou Yi.
Later, in its mythology, Taoism merged Chang 'e with the moon god Taiyin Xingjun into one person. Taoism regarded the moon as the essence of yin, and honored it as the queen of Taiyin Yuanjun, or the emperor of Taiyin in the Moon Palace as a filial piety and a wise king, and made a female idol.
