The theory of western medicine originated in ancient Greece, absorbed elements and atomism of ancient Greece, and transformed it into medical theory, on the basis of which we can understand and clarify human physiological and pathological phenomena and laws. A new medical system based on science and experiment has been developed in modern times. This subject is modern western medicine. Using the academic research of different disciplines and classifications and starting from experiments, micro or part of the research is carried out. It holds that matter is superior to spirit and emphasizes the materialist line. The theoretical system of traditional chinese medicine was initially formed during the Warring States Period. The four medical classics of Huang-Di' s Inner Classics, Classic of Questioning, Treatise on Febrile Diseases and Miscellaneous Diseases, and Shennong's Classic of Materia Medica can be used as signs of the preliminary formation of traditional chinese medicine theory. Traditional chinese medicine emphasizes that man is a part of nature, and there is a symbiotic relationship between man and nature. Human beings must adapt to the geography, environment, season and climate of nature, and must be integrated with nature in order to live and multiply normally. The biggest difference between traditional Chinese medicine and Western medicine lies in the way of thinking. Western medicine relies solely on medical technology to fight diseases, putting the human body and self-repair ability in a secondary position, even ignoring its existence. Western medicine believes in human wisdom, science and technology. Traditional Chinese medicine relies more on strengthening the human body's own ability to deal with diseases. In terms of "treatment" and "nourishment", it emphasizes "nourishment", "treatment" is external force, and "nourishment" is internal force, that is, the body's self-repair ability. The second difference between traditional Chinese medicine and Western medicine is whether there is a holistic view. Chinese medicine regards people as an indivisible whole. Every organ and tissue is linked together, every honor is worth every honour and every loss is worth every effort. For example, "five elements and five internal organs" believe that the most important human organs are the five internal organs. Any disease has a direct or indirect relationship with the decline of the five internal organs. Any viscera is connected with other organs by means of mutual restraint. The holistic view of TCM also embodies the relationship between man and nature, man and society. Man and nature are an integral whole, and human diseases can be treated from both natural and social aspects. For example, health preservation in four seasons in traditional Chinese medicine, including spring, summer, autumn and winter seasonal changes require people to make appropriate adjustments in food, clothing, housing and transportation, otherwise it will affect health. Western medicine has no holistic concept. People who are cured by traditional Chinese medicine, while Western medicine treats people's diseases. The third difference is that medical models are different. Western medicine is divided into branches according to the physiological system and organs, and is becoming more and more detailed. Medical specialty is becoming more and more specialized. Now there are tens of thousands of diseases, and they are being subdivided. Western medicine treatment and nursing are also clearly demarcated, nurses strictly implement doctor's orders. Medical treatment and maintenance are also separated, emphasizing rehabilitation and health. There are also different psychotherapy, Western medicine has a special psychologist for consultation and treatment. The overall manifestation of traditional Chinese medicine is that the classification of diseases is mainly based on visceral function and major causes, which tend to be rough and pay attention to comprehensive treatment. Psychotherapy runs through the whole process of treatment. The fourth difference between traditional Chinese medicine and Western medicine is the difference in diagnostic methods. TCM uses four ways of diagnosis "look, listen, question and feel the pulse". The diagnosis of Western medicine mainly depends on instruments. Instrumental diagnosis can only be the result. The instrument is lifeless, and the data obtained by the instrument can not be used to make flexible judgments according to the patient's special conditions, such as the patient's face, body, behavior, and so on. The fifth difference between traditional Chinese medicine and Western medicine is that they adapt to different types of diseases. Traditional Chinese medicine adapts to chronic diseases, which are caused by the decline of body function and physique. Therefore, for chronic diseases, such as chronic prostatitis, seminal vesicle inflammation, chronic pelvic inflammatory disease and chronic endometritis, traditional Chinese medicine Diuretic and Anti-inflammatory Pills and Fuyan Pills developed by Dr. Lee play a very good role in the treatment of these chronic diseases. Western medicine has a unique approach to trauma and infectious diseases. In epidemic prevention, first aid and surgery, traditional Chinese medicine is hard to be expected. The sixth difference between traditional Chinese medicine and Western medicine is the different sources of drugs. Western medicine is a chemical synthetic medicine produced in industry and developed through laboratory research; Chinese medicine is a medicine produced by nature and tried out through the principle of "medicinal and food homology". Western medicine is simple, targeted treatment, has a quick and strong effect; Chinese medicine is complex, prescriptions pay attention to decocting methods, play a comprehensive effect. Human cells have repellent effects on Western medicine, some of which lead to drug-induced diseases, while Chinese medicine has a greater affinity, and most of them are not toxic through processing and dispensing. Most western medicine is used to treat diseases, but only when they get sick, so the effect of drugs is simple and specific; while traditional Chinese medicine can treat diseases, but also health care. The difference between traditional Chinese medicine and Western medicine is the difference between two cultures and two philosophies. For traditional Chinese medicine, we should deeply understand it and have warmth and respect for it. Developing traditional Chinese medicine is not the resistance of one school of medicine to another, but the common promotion of the progress of human medicine in the exchange of different medical traditions.
