Gu Zhaozhao, the concubine of Dingbeihou Mansion in the Daning Dynasty, was designed by her aunt Wang to be a "silly girl" because of her mother's early death. In fact, she tolerated it for ten years. With her photographic memory, the medical skills passed down by her mother and her precise insight into people's hearts, she used "silliness" as a cover to gradually tear apart her aunt's sinister disguise - revealing the truth about how she poisoned her mother. Uncovering the hypocrisy of her eldest sister Gu Mingwei, she enlisted the concubines and old servants in the backyard to form a powerful force. In the end, she made the Wang family lose the trust of the Hou Mansion and Gu Mingwei lost her reputation. She successfully controlled the power of the Hou Mansion. At the same time, she got to know and stay with the general Shen Yanqing, and realized the counterattack from "the helpless and foolish girl" to the "Head of the Hou Mansion".
