Hippocrates studied medical knowledge with his father since childhood. When he was young, he visited Egypt and studied medical literature in Egypt. Later, he founded a medical school in Kos Island and gave lectures in Athens and other cities. Hippocrates, known as the "father of medicine", put forward the theory of body fluid, which holds that the human body is composed of four kinds of body fluids: blood, mucus, yellow bile and black bile. The different coordination of these four kinds of body fluids makes people have different constitutions. He also believes that disease is a developing phenomenon, and doctors should not only treat diseases but also save lives, which changed the concept that medicine was based on witchcraft and religion at that time. Hippocrates advocated paying attention to the influence of patients' personality characteristics, environmental factors and lifestyle on diseases, not only paying attention to drug treatment, but also paying attention to hygiene and diet treatment. We should not only pay attention to symptomatic treatment, but also pay attention to prevention. These medical views have a great influence on the development of western medicine later.
There are many students in Hippocrates. These students inherited his medical skills and wrote more than 60 medical articles, which were later compiled into a book, The Collected Works of Hippocrates.
