Chinese medicine brings together a variety of disciplines including Chinese culture, philosophical thought, and humanistic environment. It is a unique life science that serves the purpose of health maintenance, health care, prevention and medical treatment in human life. For thousands of years, famous doctors have emerged and made great contributions to the reproduction and prosperity of the Chinese nation by using Chinese medicine. “Chinese medicine is a great treasure trove that should be explored and improved with great efforts.” Facing the ancient and magical Chinese medicine, and after twenty years of research and exploration, I deeply appreciate the different roles of each of the four diagnoses in practice. Especially, the diagnosis of looking and cutting plays a pivotal role in the process of disease diagnosis. Now, we will analyze their correlation with the five Tibetan diagnoses and discuss with you to improve them. The “Difficult Classic of 61 Difficulties” says: “The Classic says that to look and know is called God; to hear and know is called Saint; to ask and know is called work; to cut the pulse and know is called skill. What is it? However, those who look to know, look to see its five colors to know its disease; those who hear to know, hear its five sounds to distinguish its disease; those who ask to know, hear its desired five flavors to know where its disease starts; those who cut the pulse to know, diagnose its inch mouth, see its deficiency, to know its disease, the disease in which the Tibetan government also. The sutra says: outside the knowledge of, said saint: within the knowledge of, said God. This is also known as.” Chinese medicine’s diagnosis mainly includes looking at the form of God, God has the spirit, spirit and eyes, we believe that the eyes are the focus of observation. The eyes can be divided into the gods, that is, jingling, this patient is serious, self-confidence is very strong, brain power, physical exertion, clinical susceptibility to kidney deficiency, such as waist i fatigue, double lower limb weakness, energy, physical strength decline, more so after work, do things with a heart but not enough power. If the eyes are dull and dull, this patient is narrow-minded, smaller, heavy-hearted, prone to the evidence of melancholy, too heavy psychological burden. If the eyes are lax, the patient is prone to no one in sight, carelessness, and an uncaring attitude toward things, and the patient is prone to the evidence of lack of heart energy. If the eye circle is black and the white eye is red, it belongs to liver heat and is prone to the evidence of hyperactivity of liver yang, mostly seen in insomnia and distraction, dizziness and tinnitus, poor sleep, more nightmares, unable to persuade, persuaded even more, easy to regret doing things, in contradiction. Dark circles around the eyes, drooping eyelids, and filled eye bands are heavy with phlegm and dampness, and are prone to the evidence of phlegm and stasis. If we see women over 40 years of age, with a strong Guan pulse and a sunken ulnar pulse, we often see chest tightness and stomach distension, swallowing acid in the diaphragm, not thinking about eating and drinking, swelling after eating, and a yellowish complexion, which is a sign of heavy dampness; a flushed face is a sign of yin deficiency and fire; a greenish black lip is a sign of insufficient heart pulse and is prone to hypoxia and ischemia, which is a sign of pulmonary emphysema; a flushed lip or a bright red lip is a sign of food stagnation and fire; a pale lip is a sign of Qi and blood deficiency and a sign of Yang Qi weakness; a flushed lip or a bright red lip is a sign of food stagnation and fire; a pale lip is a sign of Qi and blood deficiency and a sign of Yang Qi weakness. If the hair falls out, it is a sign of brain overuse and liver and kidney yin deficiency. 1, the key to diagnosis is to look at the tongue, the tongue moss to determine the reality of deficiency in the four diagnoses only the most objective tongue diagnosis. Tongue diagnosis is mainly observed directly by the doctor and is divided into three parts: tongue coating, tongue texture and tongue body. Tongue diagnosis can objectively reflect the changes of the patient’s body and is very important for the accurate diagnosis of diseases. The color of the tongue is observed, yellow moss is hot, white moss is cold. The thick moss is solid, which is phlegm-damp or food obstruction; the thin moss is normal, superficial or deficiency, which is deficiency of qi, blood, yin and yang. Observe its moistening and dryness. A moist tongue is normal and does not injure yin and fluid, while a dry tongue injures yin and loses fluid; observe its color. The tongue is fat and thin, the tongue is fat, i.e. tooth mark tongue or skirt tongue, which is Yang deficiency evidence, and thin tongue is Yin deficiency evidence. Most of the tongue changes are critical evidence. Such as tongue roll, tongue tremor, tongue distortion, tongue impotence, all belong to the stroke. In addition, the tongue body is divided into five organs, the tip of the tongue for the heart and lungs, the middle for the spleen and stomach, the two sides for the liver and gallbladder, and the root for the two kidneys. If the tip of the tongue is red, the heart and lungs are hot, with dry mouth, irritability, insomnia and nervous sweating; if the tip of the tongue is petechiae, chest tightness, shortness of breath and pain in the precordial area; if the middle part of the tongue is greasy, the middle jiao is damp heat, with distention and fullness, loss of appetite, sticky mouth, bitterness, heavy body, sticky stools or loose stools; if the middle part of the tongue has a map tongue, it is easy to see dry mouth and desire to drink, sometimes acidity, dyspepsia and indigestion. When there is red tongue without moss in the middle of the tongue, it can be seen as burning in the stomach, dry mouth, thirst for cold drinks, sleeplessness, dry stools and so on. When the root of the tongue is greasy with moss, it is easy to see lumbar sleepiness, heavy lower limbs, unpleasant urination and sticky stools; when the root of the tongue is peeling off, it is disturbed and insomnia, lumbar pain and dry mouth leading to drinking. When the tongue is purple and dark on both sides, the patient is emotionally uncomfortable, impatient and irritable, with fullness in both sides, and in women, irritability and crying, irregular menstruation, or menopausal syndrome. When the tongue is greasy on both sides, it is easy to see damp-heat in the liver and gallbladder, bitter mouth and sticky mouth, loss of appetite, and fullness and distension in both sides. Although tongue diagnosis can be observed directly, it often produces errors due to the influence of light, differences in visual inspection and factors such as staining and diet. Therefore, it should be carefully observed and treated seriously. 2, pulse diagnosis in the clinical evidence must not be lost three fingers cut pulse is the mark of Chinese medicine, pulse diagnosis has formed its own system, called “pulse diagnosis science”, is an important part of Chinese medicine. Pulse diagnosis is listed at the end of the four diagnostic methods of looking, hearing, asking and cutting, but it is the only diagnostic method or technique that touches the body and has an irreplaceable status. Pulse diagnosis is also a very comprehensive and complex technical operation. In the preface to the Pulse Classic, Wang Shuhe has commented on the pulse method: “It is easy to understand in the chest, but difficult to understand under the fingers”, indicating the difficulty of identifying the pulse method under the fingers. For example, the string pulse, tight pulse, flooded pulse, solid pulse, slippery pulse, sore pulse, etc., theoretically and textually can be described clearly and distinguished, but to “under the finger” is very difficult to identify. As for some of the pulses in the Nei Jing, such as the “House Leak Pulse”, “Bird Pecking Pulse”, “Dissolving Pulse”, “Shrimp Swimming Pulse “, “kettle boiling pulse”, “scattered leaf pulse”, “provincial guest pulse”, “cross-frame pulse “, “cross lacquer veins”, “decadent earth veins” and so on will be more difficult to understand under the finger. There is a saying: “the pulse is subtle, its body is difficult to identify”. Although the pulse diagnosis is complex, but from the clinical reality, pulse diagnosis can not be lost. We believe that pulse diagnosis should be coarse rather than fine. Advocate to distinguish the nine main pulse, the combination of a variety of part-time pulse. Floating pulse: pulse position superficial, lightly taken that is obtained, heavy pressure slightly reduced and not empty, lifting the general and surplus, the main surface evidence. Sinking pulse: the pulse is located deep in, lightly taken but not answered, heavy pressure is obtained, the main evidence of the inner organs, for the five organs disease. Late pulse: the pulse rate is slow, one breath is less than four to, the main deficiency cold evidence, for Yang Qi deficiency. Numerical pulse: the pulse rate is fast, with one breath of five or more, mainly heat evidence, and there is a distinction between deficiency and reality in the clinical evidence. Slippery pulse: the pulse is fluent, like a rolling pearl on a plate, mainly phlegm, food stagnation, damp heat. Astringent pulse: the pulse is not smooth, like a knife scraping bamboo, mainly stasis of blood. Blood vessels are not smooth. String pulse: The pulse comes strong, like pressing a bowstring, mainly due to Liver Qi stagnation and body pain. Thin pulse: The pulse is thin, like a thread like silk, and it is a weakness of Qi, Blood, Yin and Yang. Knotted and promoted pulse: irregular pulse rate. The pulse is late, sometimes with a stop, without a constant number for the knot. Pulse number, sometimes there is a stop, no constant number for promotion. Fixed number of aborts for generation, for bradycardia. Knot generation prolongation are serious evidence, belong to the category of cardiac arrhythmia. Most of the common clinical evidence is the concurrent pulse. Its outline: floating tight wind-cold, floating number wind-heat, floating moistened summer heat, floating but powerful table real, floating but powerless table deficiency; sinking late internal cold, sinking number internal heat, sinking slippery phlegm, food obstruction, sinking astringent blood stasis, sinking fine blood deficiency, yin deficiency; sinking late qi stagnation cold condensation, sinking number qi stagnation heat congestion, sinking slippery qi stagnation phlegm, sinking astringent qi stagnation blood stasis, sinking fine yin deficiency yang hyperactivity; sinking fine qi deficiency yang failure, fine number yin deficiency internal heat; knotted generation phlegm, blood stasis internal obstruction, qi deficiency can not transport blood The pulse can be differentiated according to the above. According to the above pulse, we can distinguish between the eight categories of cold, heat, deficiency and yin and yang, which should be carefully appreciated at the time of clinical evidence. The main distinction is between real and imaginary cold and heat, and mastering its essentials, so that the application of clinical evidence can be easily understood and understood in the chest. Specific distinctions are as follows. The left pulse is heart, liver, left kidney (water); the right pulse is lung, spleen, right kidney (fire). The right inch is floating, mainly due to external symptoms; the right inch is sunken, mainly due to weakening of the respiratory system; the right Guan is stringing and slippery, mainly due to damp-heat in the spleen and stomach, and failure of transportation and transformation; the right Guan is sunken, mainly due to weakening of the digestive system; the right ruler is stringing and slippery, mainly due to damp-heat in the lower jiao, and the meridians are not smooth; the right ruler is sunken, mainly due to weakening of the immune system. The left inch is stringy and slippery, main heart meridian solid heat, the left inch is sunken, main heart system function is weakened; the left Guan is stringy and slippery, main liver and gallbladder damp-heat, Qi disorder or emotional agitation, the left Guan is sunken, main liver and gallbladder digestive system function is weakened or emotional depression; the left ruler is stringy and slippery, main lower jiao damp-heat, meridian disorder, the left ruler is sunken, main endocrine system function is weakened. In the process of diagnosing diseases, it is necessary to combine the four diagnoses in order to have a higher accuracy rate. However, in the early stage of the disease, i.e., subhealth state, fatigue syndrome, when the organs are not substantially damaged, the internal dysfunction of the internal organs can be determined through the external manifestations of the patient. This can provide a basis for early diagnosis and prevention of diseases.
