Shen Zhaoning, the adopted daughter of the Marquis of Ning'an, is actually the legitimate daughter of her late original wife. She became an "adopted daughter" because her stepmother Zhou changed her identity. For many years, she was bullied by her concubine Shen Zhaoyue and her stepmother's hypocritical schemes. She has endured for many years, using keen observation and psychological calculations as weapons. She first designed to expose the "jealous" true face of her stepmother, and then used the concubine's marriage robbery to rebel against her. She gradually collected evidence of her mother's murder, and finally regained her identity as a legitimate daughter and the power of the Hou Mansion. At the same time, she cooperated with the third prince Li Zhaoming, who was lurking to investigate the conspiracy of the Hou Mansion, to smash the Zhou family's plan to seize power, and became the real controller of the Hou Mansion. Highlights: The whole process of psychological warfare output, the heroine uses the calculation of "returning a favor to the other" to make the villain reap the consequences. Every counterattack accurately pokes at the enemy's weakness (such as the stepmother cares about reputation, the concubine cares about marriage), and the most refreshing scene comes from the famous scene where the villain "shoots himself in the foot".
