Du Di's mother was infected with trachea and digestive tract due to long-term intubation and hydronephrosis. Huang Yunling was worried about infecting the fetus, so she decided to give Zhang Xiufen a caesarean section. Du Yongfu called Du Di and begged Du Di to save Zhang Xiufen and his son. Du Di asked to attend Zhang Xiufen's operation, but Huang Yunling couldn't help her, so she had to attend.

Huang Yunling gave birth to a daughter for Zhang Xiufen by caesarean section. Du Di took the initiative to stitch Zhang Xiufen. Feng and the nurse in neonatology department took the child away. Du Yongfu suspected that he was holding the wrong child. Du Di had to admit that he cheated him when he was a child, and Du Yongfu gave Du a slap in the face.

When Tian Yunshan heard the news, Du Yongfu knelt on the ground and begged Tian Yunshan to be his master. He listened to Du Di's words and always thought that Zhang Xiufen was pregnant with a son, which made her suffer so much and has not recovered yet. Although the medical staff tried their best to rescue Zhang Xiufen, she died after treatment. Du Di was heartbroken when she learned that her mother Zhang Xiufen was brain dead, and vowed to take good care of her sister.

Du Di arranged the ashes of her mother Zhang Xiufen, and Liu Nianbai and Wu Congrui stayed with her all the time. Du Di tried to make her proud through her own efforts, but she died long ago.

Liu Nianbai came to Du Yongfu and showed him his daughter's photo. Du Yongfu remembered his dead wife Zhang Xiufen and wept bitterly. Liu Nianbai took the opportunity to persuade him to withdraw the lawsuit against Du Di, and also briefly described Du Di's painstaking efforts and efforts in college.
