Emperor Zhaoming Xi wanted to appoint a heir, but the four princes tried every means to shirk it - the eldest prince shaved his head and became a monk, the second prince joined the Taoist sect, the third prince pretended to be naughty, and the fourth prince even tried to commit suicide. Just when the emperor was troubled, he unexpectedly learned that there was a living fifth prince named Ye Zhanzhao hiding in the cold palace. Ye Zhanzhao walked out of the cold palace and was unexpectedly appointed as the prince by the emperor. Faced with the unique temptations of his four brothers, he calmly responded with his wisdom, and finally successfully succeeded to the throne, worked hard to govern, became a wise monarch, and wrote a unique royal legend.
