After Wen Ning gave birth in 1983, her husband Yan Gang swapped his biological daughter with his mistress's daughter Yan Lingling. Wen Ning was conscious at the time but was unable to stop it. Wen Ning has pretended to dislike his biological daughter for many years, taking advantage of the conflict between Yan Ruyu and Yan Lingling to make Liu Jinlan and Yan Ruyu suffer the consequences, while collecting evidence of Yan Gang's crime. Wen Ning met Mingzhu by chance and suspected that she was his biological daughter. During the paternity test, Yan Gang sabotaged it. Mingzhu was framed and kicked out of the company and kidnapped by Yan Gang. After Wen Ning learned the truth, he signed a contract to pay 50 million to save Mingzhu. Later, he discovered that Yan Gang had lost all the money, and the poisoned school uniform incident broke out. Wen Ning was charged with protecting Mingzhu and was imprisoned.
