If a doctor's strength lies not in his frequent or late use of drugs, but in the balance between his understanding of the disease and the patient's physical condition, he will not rely too much on medical treatment, and the abuse of medical treatment is only a way to alleviate the patient's illness, so no upright doctor dares to assert to any patient.
