The legitimate daughter Shen Yunnuan showed up at a polo match with a beaded hairpin left by her biological mother. Xiao Yan promised to win it back for her, but he deliberately abstained to please his concubine Shen Ruying, forcing her to marry her as an equal wife, and even allowed her family to embezzle her mother's dowry. When Shen Yunnuan was heartbroken, Jiang Yunzhou, the prince of Dingbeihou, came to his house with a pearl hairpin and asked to marry her in accordance with his mother's last wish. Three days later, Shili Hongzhuang married her into the house. Xiao Yan and his concubine suffered the consequences, and the Shen family declined, but Shen Yunnuan married a good man, had two children, received a royal title, and finally lived a happy life.
