Legend had it that Chang'e was a beautiful and kind woman, and her husband Hou Yi was a brilliant archer.
During a time, thousands of years ago, when there were ten suns, the Mortal Realm could not endure the smoldering heat. To save the realm, Lord Archer Hou Yi shot down nine of the ten suns, leaving behind just one.
Hou Yi was respected as the Mortal Realm's hero and received an elixir of immortality from the Queen Mother of the west as a reward for saving the Realm and its people.
However, the elixir was only enough for one person, and Hou Yi didn't want to gain immortality without his beloved wife. So, he did not consume it straight away, but let Chang'e keep it with her.
