The youngest daughter of Emperor Yongle Zhu Di, the fifth princess Chang Ning, whose maiden name was Xiyao, was the daughter of a treacherous minister during the Jing Dynasty. She hid in Tibet and suffered from displacement. She was also used to seeing devastation, which made her compassionate and compassionate.
Xiyao married Mu Xin, the younger brother of the Marquis of Xiping, in the first year of Yongle. In accordance with the holy will, he raised Zhu Zhanji, the son of the eldest emperor brother Zhu Gaochi, and Zhu Zhanhe, the son of the second emperor brother Zhu Gaoxu. Zhu Di's behavior caused a lot of speculation. As smart as Xiyao, he vaguely understood his father's thoughts, and even realized that his eldest brother's position as prince was in jeopardy. She knew very well that the eldest brother's benevolence and the second brother's cruelty would be unsatisfactory if chosen as the heir to the throne. She wants to help her father choose a successor who can benefit the world, and does not want to cause further disputes and bring disaster to the people.
