There are tales of many Suns found in Chinese mythology. Xihe is the Sun Goddess.
The Ten Suns
Xihe was the wife of the Emperor Jun, who was the most mighty God of them all. They had ten Suns together, and lived near a mulberry tree. The child-Suns slept in the lower branches of the tree. However, every morning Xihe bathed one of her children in the river and then let him/her fly on the back a crow to the top of the mulberry tree. Then the child-Sun would fly up into the sky, and be the Sun for the day. Each of the child-Suns took turns doing this so that there would be light everyday.
One day, though, the child-Suns all went into the sky at the same time. The heat was too much, and it scorched the earth so that many people died of hunger. Yi was an archer and he tried to talk the child-Suns into coming home to no avail. Yi decided to shoot the child-Suns out of the sky, one by one. Only one escaped, and now it has to be the Sun everyday so that the world has light.
