According to Chinese folklore, the earth once had 10 suns circling over it, each taking its turn in illuminating the earth with its light. But one day all the suns appeared together and began to scorch the earth. An archer named Hou Yi saved the earth by shooting down all but one sun, and he threatened to eliminate that one as well. This archer then stole the "Elixir of Life" from a goddess and tightened his control over the country. The archer's beautiful wife, named Chang Er, drank the elixir in order to save the people from her husband's tyrannical rule. After drinking the elixir, she became light and floated upwards to the moon. Hou Yi loved his wife so much, he didn't shoot down the moon and ended his oppression. The moon festival was celebrated since that time in honor of Chang Er.
