The novel "Romance of the Three Kingdoms" describes a medical dispute between Hua Tuo and Cao Cao. Hua Tuo was suspected by Cao Cao for proposing a craniotomy surgery plan and ultimately died. Hua Tuo was a famous surgeon in history, with superb medical skills, but at that time, practicing medicine had to follow legal regulations. Modern law has a clear requirement for doctors to inform patients of their condition and treatment plan. If Cao Cao's behavior is evaluated according to modern law, it constitutes the crime of intentional homicide. Doctors' practice is protected by law, and any behavior that harms doctors will be held accountable by law. Respecting doctors is respecting life, and a good doctor-patient relationship should be maintained.
