" Once when there were no rivers on the earth, the Jade Dragon was in charge of clouds. She decided when and where the clouds would rain upon the land and when they would stop. She was very proud of her power and of the reverence the people of earth paid her. Jade Dragon had four dragon children: Pearl, Yellow, Long, and Black. They were large and strong and good and kind. They helped Jade Dragon with her work, and whenever they flew in the sky she was overwhelmed with love and pride. "
