Lin Wanqing, an emergency doctor who transferred to pediatrics, used reason and warmth to break through doubts in the workplace. Faced with the need to treat patients without medical care and a medical crisis, she fought side by side with deputy director Gu Mingxiu, who had suffered from medical violence.
