Yu Ning is a princess of the Yehenala clan in the Manchu Qing Dynasty. After the fall of the Qing Dynasty, she went north to Pingjin to seek refuge with the Zhang family, who was engaged to be married. Zhang Yaolin and Yu Ning had a relationship when they were young, but they were not satisfied with the sudden engagement, and there was a new-style female student Zhang Hanzhi around them. The Zhang family did not approve of the new-style girl Zhang Hanzhi, and preferred Yu Ning as the wife of their second son. Yu Ning had to intervene in their relationship for the sake of the safety of the clan, which made Zhang Yaolin resentful of her.
