When Emperor Yao became old, he became distressed over the fact that his 9 sons were all useless, only knew how to spend their days enjoying themselves with wine and song. Yao asked his administers, the Four Mountains, to propose a suitable successor. Yao then heard of Shun's tales. Wise Yao did not want to simply believe in the tales about Shun, so he decided to test Shun. Yao gave a district to Shun to govern and married his two daughters to him, with a small dowry of a new house and some money.
