2. Look at the skin: the skin is white with powder, shiny, elastic, wrinkle-free and spot-free, indicating that the blood is sufficient. On the other hand, rough skin, dull complexion, black hair, yellow hair, white hair, blue hair, redness and long spots all represent poor physical condition and insufficient qi and blood. 3. Look at the hair: black, thick and supple hair means sufficient blood, and dry hair, hair loss, yellowing, white hair and split ends are all insufficient blood. 4. Look at the ears: Nowadays, people's physical fitness is getting worse and worse. Look carefully if you don't believe me. Now people's ears are small, they look more and more stiff, and their shapes are a little deformed. Even children and young people rarely see big, round, fat and full ears. But these big ears are very common in the elderly, which shows that the physical quality of people in the past was obviously stronger than that of modern people. Children look at ears and shapes, while adults mainly look at the acquired situation except the shape, mainly the color, spots and pain. If it is light pink, shiny, without spots, wrinkles and fullness, it means it is full of blood. And insipid, insipid is the decline of qi and blood. If the ears are atrophied, dull, spotted and wrinkled, it means that people's kidney function is beginning to fail, so you should pay attention.
5. Touch the temperature of your hands: If your hands are warm all the year round, it means that this person is full of blood. If the palm is hot or sweaty or the hands are cold, it is qi and blood deficiency. 6. Look at the fingertips: whether it is a child or an adult, if the fingertips are flat, weak and thin, it means that the blood is insufficient, while the fingertips are full and the meat is elastic, indicating that the blood is sufficient. 7. Look at the blue veins: If you see the blue veins on the index finger of an adult, it means that the digestive function is not good when you are young, and this state continues into adulthood. This kind of person is weak, with deficiency of both qi and blood. If you see veins standing out on your little finger, it means you have kidney deficiency. If there are many and deep lines near the horizontal line of the wrist under the palm of your hand, it means malnutrition, physical weakness and lack of qi and blood when you were a child. In adulthood, such women are prone to gynecological diseases, while men are prone to prostate hypertrophy and gout. 8. Look at the half-moon on the nail: Under normal circumstances, the half-moon should be all except the little finger. On the thumb, the half moon should account for 1/4~ 1/5 of the nail area, and the other index finger, middle finger and ring finger should not exceed 1/5. If there is no half moon on the finger, or only half moon on the thumb, it means that the human body is cold, the circulation function is poor, and the blood is insufficient, so that the blood cannot reach the fingertips. If there are too many months, it is easy to suffer from diseases such as hyperthyroidism and high blood pressure. 9. Look at the vertical line on the nail: it only appears in the hands of adults, but not children. When adults have vertical stripes on their nails, they must be vigilant, which shows that both qi and blood are deficient and overdraft is a symbol of aging. 10. Look at the gums: children are not obvious, mainly adults. Gingival atrophy represents deficiency of qi and blood. As long as it is found that the teeth are getting bigger and food is more and more easily stuffed into the teeth, it is necessary to pay attention to the decline of the body and the acceleration of aging. 1 1. Look at sleep: If adults fall asleep quickly, sleep heavily and breathe evenly, like children, they will naturally wake up when they sleep, indicating that their blood is full; People who have difficulty falling asleep, are easy to wake up, have nocturia, breathe heavily or snore are all blood deficiency. 12. Watch exercise: If you feel chest tightness and shortness of breath during exercise, and fatigue is difficult to recover, your blood is insufficient, and people who are full of energy and relaxed after exercise will be fine. Please adopt it.
