Zhang Baoguo is the husband of Sister Zeng, a wife living in the family compound. He is described as terrified and desperate when his wife goes into labor while unconscious. His voice trembles and his eyes are red with fear and worry upon learning the severity of the situation. When Yang Qingyan asks about his wife's heart condition, he breaks down in tears, explaining that his wife has had congenital heart disease since childhood and they never dared think about having children, but she insisted on giving him a baby no matter what. He immediately sprints to prepare food for his wife and feeds her spoonful by spoonful with trembling hands. After the successful delivery of a baby girl, he is overwhelmed with emotion and repeatedly thanks Yang Qingyan for saving both his wife and child.
