First, look 1, look at the shape: the shape looks obese, but did not reach the standard of obesity, just overweight; muscle touch firm, flexible action, most of them are calm, damp heat, phlegm damp physique, qi deficiency is not obvious. If very lazy, action dragging, walking dragging, the whole person seems heavy and tired, most of such people are between the phlegm and dampness between the Yang deficiency or Qi deficiency constitution. The body is thin, the weight is not up to standard, and the subcutaneous fat is low, basically a deficiency physique. If thin and muscle flabby, yellow face, speak as if wandering, low voice, mainly qi deficiency physique. If lean and sturdy, flexible, good energy, usually Yin deficiency internal heat constitution. If the shape is dry and thin, the face and lips are dark, the skin is dry, the tongue is purple and dark, blood stasis is the main body. 2, look at the face color: Chinese people are yellow, the normal face color should be yellow and lustrous, through a little blood color. Of course, there are shades of skin color, whether fair or dark, there should be luster. A shriveled face, i.e. yellow without luster and without blood, is a blood deficiency. Yellow and greasy skin is mostly damp heat. Dark face and lips, dark circles under the eyes before menstruation or often with cold or insomnia are mostly blood stasis. If the face is white and lacks blood and luster, it is Yang deficiency.3. Look at the tongue: a fat, light and tender tongue with soft texture indicates a deficient constitution, Yang deficiency and Qi deficiency are common. If the tongue is fat and very red, it is a hot body, and generally has a strong appetite. Feeling that the tongue is obviously distended, the tip of the tongue is red and red, and it seems to bite the tongue when eating, indicates that one has eaten too much hot stuff or too much, and is prone to mouth sores. A thin, small, pale and shriveled tongue is a deficiency of qi and blood. A small, but red tongue with little tongue coating is Yin deficiency or internal heat. A purple and dark tongue, or petechiae and petechiae, is Blood stasis. The tongue often has teeth marks on the edges, which is Qi deficiency. A tongue that is often thick and does not easily recede is either damp-heat or phlegm-damp. If there is no tongue moss, it is Yin deficiency. 4. Look at the eyes: a glowing gaze may favor a hot body or a calm body. A dull gaze is a deficient constitution, with Qi deficiency, Blood deficiency, and Yang deficiency all present. Fatty deposits on the eye sclera, or very fine blood filaments that look cloudy all year round, are mostly seen in blood stasis, phlegm-damp and damp-heat constitutions. There is a more specific type of Yang deficiency physique with upper heat and lower cold, which will also see cloudy eyes.5. Look at the nails: the crescent is the white, rounded shape at the root of the finger nails. A normal crescent should be milky white, and the whiter the healthier. A normal crescent accounts for about 1/5 of the entire nail cover, if less than 1/5, it means there is cold in the body; if more than 1/5, it means there is heat in the body. The thumb and middle finger should have crescent teeth, which means our body is moderately hot and cold, and there will be no major health problems. 10 fingers have no crescent teeth and have not had them since childhood, which means a cold body; if they used to have them and now they don’t, that means the body is cold and heavy. When the body is hot, 10 fingers have crescent teeth, there are more than 7 crescent teeth belong to the hot or hot body. Second, smell 1, listen to the sound: light and shallow voice, no mid-air, is a gas deficiency. Sound bottom gas enough, the gas is sufficient, usually phlegm damp or calm body. 2, smell: often sweat, body odor is particularly large, is phlegm damp or damp heat body. Often have breath, indicating that there is internal heat, stagnation. Phlegm damp, damp heat, Yin deficiency internal heat, upper heat and lower cold people are prone to bad breath. Third, ask 1, ask the cold and heat: fear of cold, summer but not winter, perennial cold hands and feet, especially in winter, cold hands over the elbows and feet cold knees, sleep not hot nest, suffering from every cold is the onset or exacerbation of chronic diseases, basically can be judged as Yang deficiency body. Those who are afraid of heat, tolerate winter but not summer, have warm extremities, especially in the summer when the palms and feet are hot, and like to blow the air conditioner and drink cold drinks, have a hot constitution. Some people, especially women, are afraid of cold in winter and heat in summer, and are intolerant of cold and heat; they wear a lot of clothes when they are cold, and drink cold drinks and blow air conditioners when they are hot, and have poor adaptability to climate. Commonly found in qi-depression physique, qi-vacuity physique. The woman with a deficient blood body will also be afraid of cold, cold hands and feet, but usually accompanied by dizziness, palpitations, dreamy, yellowish face, menstruation less colorful blood deficiency performance. 2, ask sweat: less sweat or no sweat, energy metabolism will be slow and not smooth, smothered inside, endogenous phlegm, damp heat, damp heat. Too much sweating, such as sweating during the day without activity (spontaneous sweating), sweating at night after going to sleep (night sweating) are not normal, seen in the Qi deficiency, Yin deficiency body. People who sweat little or no sweat and can eat are often inevitably obese, while those who sweat spontaneously or night sweat, have poor appetite and small meals will suffer from weight loss, insomnia, forgetfulness, and panic. Exercise, hot food, hot drinks, when the day is hot, than others obviously sweat less person, usually seen in qi depression, damp heat, phlegm damp physique, less sweat without sweat will be easy to fat, swelling, amenorrhea, irritability, acne, etc.. Because of the low energy consumption, poor metabolism of water and fluid, internal heat can not be dispersed. Fourth, cut the pulse is strong, neat rhythm, indicating good health, at least good heart and lung function. If you can’t feel the pulse for half a day, it’s hard to feel it, but it feels very thin, if anything, it’s a deficient body; if the pulse is thin and the appetite is good, it will be easy to gain weight. A pulse that resembles a straight string is called the string pulse, also called the liver pulse, which means that the liver is not functioning properly. In a calm state, a quicker pulse is heat (actual heat or deficiency heat); a significantly slower pulse is Yang deficiency.
