The Queen Mother of the West was moved by Hou Yi's feat and gave him an elixir of life. Feng Meng, a treacherous and greedy villain, was bent on getting the elixir, and took advantage of Houyi's hunting to coerce Chang 'e into handing it over with his sword.
Chang 'e knew that she was no match for Meng Peng. In times of crisis, she made a decisive decision, turned around and opened the treasure chest, took out the fairy medicine and swallowed it in one gulp. As soon as she swallowed the medicine, she flew into the sky at once. Because Chang 'e was worried about her husband, she flew to the nearest moon and became a fairy.
Extended information Chang 'e is the moon fairy in China mythology. In The Classic of Mountains and Seas, the Emperor of Heaven in the Middle Ages, the daughter of the Emperor, and the wife of Hou Yi (sense of righteousness) were called (Heng E) because of their extraordinary beauty, but in order to avoid the taboo of the Emperor China of the Western Han Dynasty, they were renamed as E, also known as Chang 'e, and some people called them Chang 'e.
In mythology, Dayi lived in the Guanghan Palace above the moon because she took the elixir of the Queen Mother of the West.
Before the Eastern Han Dynasty, there was no data to show that Chang 'e and Yi were husband and wife, and Guizang explained that they might be husband and wife by comparing divinatory symbols. It was not until Gaoyou annotated Huai Nan Zi that Chang 'e was Hou Yi's wife. In some folklore, Chang 'e and Xing Jun, the Taoist goddess of the lunar calendar, are combined into one, and are honored as the Moon Palace Huang Huasu, Yao Yuan's net victory over Hou Taiyin Yuan Jun, or the Moon Palace Huang Junxiao and Wang Ming, which is a female image.
