Zhao Jianguo, the daughter of a butcher, enters the palace to compete for the position of Crown Princess. She only intends to go through the motions and return home to inherit her family's pork stall. Unexpectedly, her unusual name leads Crown Prince Xiao Chengze to mistake her for a secret agent of the Mysterious Bird organization. Her special pig-hoof knot for tying up pigs and her ability to identify fresh meat are all imagined by the Crown Prince to be extraordinary secret techniques. When Liu Ruoyun deliberately makes things difficult for her and an embezzlement case involving Vice Minister Zhou arises, Jianguo easily resolves both using her butchering skills. By the time the misunderstanding is cleared up, the Crown Prince has already fallen for her straightforward and spirited personality. When a rebellion breaks out outside the city, Zhao Jianguo subdues the rebels with her bare hands and saves the Empress Dowager, firmly securing her position as Crown Princess. In the end, the Crown Prince opens a royal pork shop for her. Everyone calls her the Crown Princess, but all she wants is for people to call her Comrade Jianguo.
