Jiang Xiaodou, a shrew who sells tofu in the West Market, was hired by the old lady of Zhenbei Palace with a large sum of money as the crown prince because of her sharp tongue and ability to hit her. She was just to protect the "weak and unable to take care of himself" crown prince Chu Lingzhou from being bullied by his concubines. After her marriage, she stood up for Chu Lingzhou many times, but gradually discovered that he had a secret - the seemingly sickly prince was actually the late emperor's son, General Zhenbei, who held a heavy army. He pretended to be sick to avoid persecution by the prince. During the Imperial City Incident, Chu Lingzhou showed his iron-blooded nature and killed the regicide and false emperor to ascend the throne. After going through deception and twists and turns, the two finally reached a tacit understanding. Jiang Xiaodou accompanied Chu Lingzhou with his true self, and lived a happy life of "half palace and half city".
