During the Hongwu period, the imperial power was initially established, and undercurrents surged among the princes. {Zhu Ningyue} As Zhu Yuanzhang's favorite Anqing princess, she is smart and far-sighted, and is unwilling to become a pawn in a political marriage. She took the initiative to request an order to marry the eldest son of Xu Da, the founding hero of the country, {Xu Yungong}. Prince Zhu Biao suddenly died of illness, and the struggle for the throne suddenly broke out. King Zhu Di of Yan showed his talents, while the emperor's grandson Zhu Yunwen was weak. Zhu Ningyue was worried about the recurrence of war and the suffering of the people, so she decided to help Zhu Yunwen stabilize the court situation. As a princess, she secretly contacted Zhongliang to spy on Zhu Di's movements; Xu Yungong relied on the military power of the Xu family to protect Zhu Yunwen's safety. However, Zhu Di launched the Jingnan Campaign in the name of "Qing Jun Side" and captured Nanjing. Zhu Yunwen's whereabouts are unknown. After Zhu Di ascended the throne, he missed the old relationship between the two, but cut off part of the military power of the Xu family. Zhu Ningyue and Xu Yungong saw through the cruelty of the imperial power, so they both resigned and went to their fiefdoms. From then on, they did not care about political affairs and spent the rest of their lives in peace.
