Although she and the fifth prince Yongqi (played by Leo Ku) finally got married, Xiaoyanzi (played by Huang Yi) did not change her naughty and mischievous nature. She teamed up with Yongqi, Erkang (played by Zhou Jie) and Ziwei (played by Ma Yili) to cause a lot of trouble, and even pretended to pass on the imperial decree to arrange for Qing'er (played by Wang Yan) and Xiaojian (played by Huang Xiaoming) to meet. In the process, Xiaoyanzi gradually figured out her own life experience, and thus developed contradictory and complex feelings towards Yongqi and the emperor, who had always been close to her. The empress dowager was worried about Yongqi's heirs, so she sent the beautiful woman Zhihua (played by Qin Lan) to Yongqi, which also caused a bigger rift between Xiaoyanzi and Yongqi. Soon, war broke out on the border, and Erkang followed the army south. He and Ziwei also faced the test of life and death... This film is adapted from the original work of the same name by the famous Taiwanese romance novelist Qiong Yao.
