1, look at the eyes: look at the eyes is actually to look at the color of the white of the eyes, as the saying goes, “people old pearl yellow”, in fact, refers to the color of the white of the eyes become cloudy, yellow, blood, which indicates that you are not enough qi and blood. The eyes can be open at any time, indicating that the blood is sufficient; conversely, bags under the eyes, dry eyes, heavy eyelids, all represent a lack of blood. 2, look at the skin: skin white with pink, lustrous, elastic, no wrinkles, no spots on behalf of sufficient qi and blood. On the contrary, rough skin, no luster, dark, yellow, white, green, red, long spots represent poor health, lack of Qi and blood. 3, look at the hair: dark, thick, smooth hair represents sufficient qi and blood, dry hair, hair loss, yellow, white, open hair are insufficient qi and blood. 4, look at the ears: now, the quality of human health is getting worse. If you don’t believe me, take a closer look. Nowadays, people’s ears are small and look more and more stiff and deformed in shape. Children and young people are rarely able to see round, fat, full of large ears. But these big ears are very common in the elderly, which means that the physical quality of people in the past was significantly stronger than that of modern people. Children look at the shape of their ears, while adults look at the shape of their ears, mainly in terms of color, spots and pain. If they are light pink, shiny, spotless, wrinkle-free, and full, they represent sufficient qi and blood. If it is dull and lusterless, it means the Qi and blood have declined. If the ears are atrophied, dull, spotted and wrinkled, it represents that the person’s kidney function is starting to fail. 5, touch the temperature of the hand: If the hand is warm all year round, it represents that the person has sufficient qi and blood, if the palm is hot or sweaty or the hand is cold, it is insufficient qi and blood. 6, look at the finger belly: whether children or adults, if the finger belly flat, weak or fingertip thin, are representative of insufficient qi and blood, while the finger belly is full, meat and elastic, it means that the qi and blood is sufficient. 7, look at the veins: If you see the veins on the index finger of adults, it means that the digestive function is not good as a child, and this state has been continued into adulthood. These people are weak and have a deficit of both qi and blood. If you see a green tendon on the little finger, it indicates a deficiency of kidney energy. If there are more and deeper lines below the palm near the transverse wrist line, it means poor nutrition as a child, weak constitution and lack of Qi and blood. As an adult, such women are prone to gynecological diseases, and men are prone to prostate hypertrophy, gout and other diseases. 8, look at the half-moon shape on the nail: under normal circumstances, the half-moon shape should be in addition to the little finger are there. If there is no half-moon on the finger or only on the thumb, it means that the person’s body is heavy with cold, poor circulation, lack of blood, so that the blood does not reach the end of the finger, if the half-moon is too much, too large, it is susceptible to hyperthyroidism, hypertension and other diseases. 9, look at the finger nails on the longitudinal lines: only in the hands of adults, children will not have. When longitudinal lines appear on the fingernails of adults, we must be vigilant, which indicates that the body is deficient in qi and blood, there is an overdraft, a symbol of aging of the body. 10, look at the gums: children are not obvious, mainly adults. Gum shrinkage represents a lack of qi and blood, as long as you find that the gap between the teeth has become larger, food is more and more easily stuffed in the gap, we should pay attention to the body has been going downhill, aging is accelerating. 11, look at sleep: adults who fall asleep as fast as children, sleep heavy, breathing evenly, a sleep until natural awakening, indicating that the blood is sufficient; and sleep difficulties, easy to wake up, night urination, deep breathing or snoring people are blood deficiency. 12, look at the movement: exercise if there is chest tightness, shortness of breath, fatigue is difficult to recover from the situation, Qi and blood is insufficient, while those who are energetic and relaxed after exercise is very good.
