When the apocalypse emperor died, he said, "Come! My brother should be Yao Shun. " What does that mean? When Zhu Youxiao, the emperor in the Revelation, died, he said to his brother Zhu Youjian, "Come here! My brother, you should be a wise emperor like Yao Shun! "
It means to pass on the throne to the fifth brother, hoping that he will become a good emperor like Yao Shun.
