Brief introduction to the Goddess Chang'e flying to the moon's story:

Iraq was the king of a poor country in ancient times. He is strong and brave, but he is tyrannical and oppressive, which makes people miserable. He wanted to live forever, so he took the elixir of the Queen Mother.

The ending of the Goddess Chang'e flying to the moon's story in Han Dynasty is very strange. People in the Han Dynasty believed that there were jade rabbits and toads in the moon. Jade rabbit doesn't know the origin, and it is said that Chang 'e later became a toad.

The story of Chang 'e taking the elixir to the moon was revealed at the latest in the divination book "Returning to Tibet" at the end of the Warring States Period, and it was not widely known until the Han Dynasty. The story of the Goddess Chang'e flying to the moon in the Goddess Chang'e flying to the moon's Huainanzi written by Liu An, the king of Huainan in the Western Han Dynasty, and Lingxian written by Zhang Heng, an astronomer in the Eastern Han Dynasty, has always had a good beginning and end.

"Lingxian" also mentioned that after Chang 'e stole the elixir of Hou Yi, she went to a fortune teller named Huang for good or ill luck. The fortune teller divined and told her that it was auspicious, but it was possible and predicted.
