Qing Nuan, a medical doctor on the road back home, performed a "textbook" rescue. Li Chunlin, who was traveling on the same train, heard the announcement that medical personnel were in urgent need of rescue.
He quickly rushed to the patient's side to start first aid treatment. The patient was convulsing on the seat, having difficulty breathing, looking pale, sweating profusely, and confused. He has a medical history of heart disease, but he drank too much with his friends before departure.
