Chang'er flew to the moon
Legend says that there were once ten suns in the sky, which made plants wither, water in rivers and lakes run dry. It's too hot to live on the sun.
Houyi, a young man who was good at archery was sympathetic with people's torture so he decided to save them. He took out his bow, ascended up to the peak of the Kunlun Mountain and shot down nine of the ten suns one by one, and he might have shot the last one if it was not called off by others. Thus the severe drought was gone.
Houyi thus was respected and honored by people as a hero. Young men who were fond of archery flocked to him to learn shooting.
Houyi later married a pretty lady called Chang'er and lived a happy life with her.
One day on his way to a friend' home in the Kunlun Mountain, Houyi came across the Heavenly Empress. Houyi was enamored of the happy life with his wife and wanted to be with her forever so he asked the Heavely Empress to give him some elixir. The elixir was strictly controlled off normal people. The Heavely Empress, however, moved by Houyi's contribution and affection to love and gave him one. The drug was said very powerful and people who took it can fly to the heaven and became a immortal immediately. However, the content was only enough for one person and Houyi was reluctant to leave his beloved wife alone on the earth so he gave the elixir to Chang'er to preserve and wanted to seek another one for his wife. Chang'er carefully stored it in a wooden box while her action was peeked by the evil Fengmeng-one of his husband's adherents.
