Su Wantang, the daughter of a wealthy businessman in Suzhou, was forced to marry Zhou Huaijin, Emperor Qingyuan of the Zhou Dynasty, in her stead because her sister was seriously ill. She originally wanted to live a idle life, but her "Buddha nature" of not participating in palace fights attracted the emperor's attention. Faced with the frame-up by the concubines, she directly admitted that "I did it," but the emperor found out that the concubines framed her. Faced with pressure from the queen mother, she accepted the punishment, and the queen mother thought she was sensible. Faced with the calculations of her descendants, she said "it's up to you" without hesitation, but the descendants themselves were exposed. In the end, she became the queen even though she was lying down, and pushed the emperor to reform the government, realizing a life in which "you can win even though you are lying down".
