This sentence was said by Sun Simiao. His main contribution lies in his book "A Thousand Gold Prescriptions". Sun Simiao believes that as a doctor, you must first have good qualities. He clearly pointed out in the preface to "A Thousand Gold Prescriptions" that "human life is of the utmost importance, and a thousand gold prescriptions are valuable, and one can help them. The virtue exceeds this, so it is named after it." Here he used the metaphor that human life is more important than a thousand pieces of gold, which is why he took the word "a thousand pieces of gold" as the true meaning of the title of his book. He also emphasized in the book that one must have a high degree of sympathy and responsibility for patients. When seeing a doctor, you must concentrate on it, and you must not "talk too much and laugh with the patient, make a lot of noise, and never talk right and wrong, show off your reputation, or slander other doctors." All patients, whether they are rich or poor, rich or poor, or close relatives and friends, must be treated equally.
