On the wedding night, the souls of the legitimate daughter of the Hou family and her fiancé exchanged. Trapped in a man's body, she despises feudal oppression and does not want to be a caged bird. As a man, she did scientific research, engaged in politics, stabilized the people, and established the country, and stirred up the court with her true talents and knowledge; but he was trapped in the boudoir, and only then did he understand the difficulty of a woman's survival. In the end, she returned to her original form as a woman, and still went down in history with her strength, becoming the number one female minister throughout the ages.
