moon festival

Hou Yi was an expert archer and he was married to Chang er .
One day 10 suns arose in the sky instead one one, blazing the Earth. Hou Yi shot down nine of the suns and he became a hero. The Emperor rewarded Hou Yi with a pill that granted eternal life. But he recommended HouYi not to take the pill immediately so HouYi took the pill home.
One day his wife Chang Er discovered the pill and took it. Instantly , she jumped out the window of a room at the top of palace, and instead of falling, she floated into the sky toward the moon.
When HouYi came back home he was angry , and he tried to fly to his wife, but he was forced to return to Earth because of strong wind.

Once a year on the fifteenth day of the full moon Houyi visites his wife .That is the reason why the moon is very full and beautifull at night.
