The Mid-Autumn Festival, also known as the Moon Festival or Mooncake Festival, is a traditional festival celebrated in Chinese culture.
In the ancient past, there was a hero named Hou Yi who was excellent at archery. His wife was Chang'e. One year, the ten suns rose in the sky together, causing great disaster to the people. Hou Yi shot down nine of the suns and left only one to provide light. An immortal admired Hou Yi and sent him the elixir of immortality. Hou Yi did not want to leave Chang'e and be immortal without her, so he let Chang'e keep the elixir. However, Peng Meng, one of his apprentices, knew this secret. So, on the fifteenth of August in the Chinese lunisolar calendar, when Hou Yi went hunting, Peng Meng broke into Hou Yi's house and forced Chang'e to give the elixir to him. Chang'e refused to do so. Instead, she swallowed it and flew into the sky. Since she loved her husband and hoped to live nearby, she chose the moon for her residence. When Hou Yi came back and learned what had happened, he felt so sad that he displayed the fruits and cakes Chang'e liked in the yard and gave sacrifices to his wife. People soon learned about these activities, and since they also were sympathetic to Chang'e they participated in these sacrifices with Hou Yi.
