In what categories did the ancient Greek physician Hippogratt classify temperaments? What are the characteristics of each?

[Question] Hippocrates' traditional theory of temperament types classified people into what and what four types according to their body fluids

[Answer 1] In order to resist the fallacy of "God-given diseases", Hippocrates actively explored the characteristics of the human body and the causes of disease, and put forward the famous "theory of body fluids". The theory of the four humors was not only a theory of disease The theory of the four humors is not only a theory of pathology, but also the earliest theory of temperament and constitution. He believed that the complex human body is composed of four kinds of body fluids: blood, mucus, yellow bile and black bile, and that the different proportions of the four kinds of body fluids in the human body form different temperaments of human beings: bile, which is impetuous and swift in action; polycythemia, which is active and sensitive in action; mucus, which is sedate and slow in action; and depression, which is fragile in nature and slow in action. For each individual, whichever fluid is predominant in his physiological characteristics corresponds to which temperament. Innate character performance, will be adjusted with the objective environmental changes in later life, the character will also change, for later generations of medical psychotherapy provides a certain guidance basis. The reason why people get sick is due to the imbalance of the four fluids. And the fluid imbalance is in turn the result of the influence of external factors. Therefore, he believes that a doctor into a certain city should first pay attention to the direction of the city, soil, climate, wind direction, water, water, eating habits, lifestyle and so on these natural environment with a close relationship between human health and disease.
