Grandfather Sun, what's the name of the moon?

Grandfather and Moon Mother are husband and wife. Their children are called stars. Originally, they lived happily. However, Grandfather Sun has a bad temper. Moon can't stand it. They left home with their children, Star. In order to avoid the sun father-in-law, the moon mother-in-law dared not come out during the day. In order to find his wife and children, Grandpa Sun came out to find them early in the morning. He didn't go home until it got dark one day. Mother-in-law, the moon and the children with stars dare to come out only when it is dark. So the sun comes out during the day and the moon and stars come out at night.
