In the early Qing Dynasty, the dramatist Li Yu was seriously ill. He did not agree to see a doctor who could prescribe a doctor to cure a disease, but a doctor who had prescribed a prescription to treat people who had died. This puzzled his wife and mother. Afterwards, Li Yu said, every doctor who can cure a disease must push it when he sees a critically ill patient. There is no ability to treat critically ill patients, and doctors who have killed people are not afraid of severe death. Although they have treated the dead, they have also gained experience. 
story?
Death and life are the unity of opposites. If doctors want to save people from critical conditions, they will face both the possibility of death and the possibility of living.
