When Princess Chu Ziqian of Changning County woke up, she turned into Lin Yan (played by He Shi), the daughter of Lin Shangshu, sitting on the wedding sedan to marry the seventh prince Zhao Qing (played by Guan Yue).Everyone thought that the Seventh Prince and Princess Changning were childhood sweethearts, but they never thought that Chu Ziqian actually claimed that the Seventh Prince not only refused to marry and humiliated her, but also poisoned her.God has given this opportunity, and Chu Ziqian will definitely use Lin Yan's identity to take revenge.
