Hand diagnosis collects diagnostic data comprehensively by observing nine areas: hand shape, finger shape, fingerprint, palmprint, hand color, nail shape and color, hand blood vessels, wrist (hand neck) and hand diagnosis. Guided by the theory of traditional Chinese medicine, based on holographic medicine, combined with syndrome differentiation of traditional Chinese and western medicine, the development trend of human health diseases is dynamically and intuitively revealed, thus providing objective diagnostic data for treatment and health care. Compared with face-to-face diagnosis, hand-to-face diagnosis has greater adaptability: it can be free from the restriction of race color, the influence of beauty, and the control of people's emotions, and it has greater Esperanto nature. Different races have the same hand pattern, which is the experience gained by doctors after hand diagnosis for people with different skin colors. The hand diagnosis introduced here is the cultural wealth accumulated by ancient and modern sages at home and abroad, which is worth studying seriously. Any form of hand diagnosis is health disease information distributed in human body, and human viscera is closely related to meridians and nerves. Palm exchanges information with them, very close. If the human brain is compared to "CPU", then the hand is a "monitor". Therefore, the performance in hand diagnosis is directly proportional to the reaction of physical health. In fact, no matter what kind of disease it is, it is more or less related to internal organs. Therefore, when suffering from a certain disease, there will always be related symptoms. At first, the symptoms are mild, and when they get worse, they will become serious and send out dangerous signals. There are six meridians running on the palm of our hand (including the back of our hand), which are closely related to the five internal organs. Therefore, when the viscera is abnormal, it will appear abnormal changes in color, texture and shape through the meridians and acupoints related to the movement of human qi, and respond to the distress signal or red light warning sent by the viscera to people, thus attracting serious attention and reminding people to nip in the bud. Understanding, learning and mastering the qualitative characteristics and changing rules of health disease information in hand diagnosis can help us to judge what color, texture and shape represent what viscera, so as to predict the disease. This is also China's medical theory and experience for thousands of years, which is undoubtedly reliable. As long as you are familiar with it and practice boldly, no matter who, when and where, even in the desolate desert, even if you leave the application of modern technology, you can re-examine and perfect it and show the medical charm of hand diagnosis-Chinese medicine inspection!
