1, the eyes have a bright look. The eyes of the gaze of the eyes, a trace of dull feeling are not, indicating full of energy, blood and vitality, and the function of the viscera and six internal organs are also very good. The Yellow Emperor’s Classic of Internal Medicine says: “The essence of the five viscera and six internal organs are all injected into the eyes and are the essence.” It means that the eyes are the place where the essence of the internal organs converge. The Yellow Emperor’s Classic of Internal Medicine also says that “the areoles of essence are the eyes, the essence of bone is the pupil, the essence of tendon is the black eye, the essence of blood is the complex, the essence of its areoles is the white eye, and the essence of muscle is the restraint”. The ancient people divided the different parts of the eye into five organs, and the whole eye socket is the expression of essence, of which the kidney is expressed in the pupil, the liver in the black eye, the heart in the blood complex of the eye, the lung in the white eye, and the spleen restrains the whole eyelid. This shows that the condition of the eyes is closely related to the essence of the five viscera and six internal organs. 2, the face is red and moist. The face is red and yellow and vague, bright and moist and subtle. The ancients said that “the 12 meridians, 365 loops, the blood is on the face”, so the color of the face is the “barometer” of the strength and weakness of the blood. Good function of the internal organs, sufficient qi and blood is rosy face, qi and blood deficiency is not lustrous face. 3, the voice is bright. The lungs are the main gas, the lungs are sufficient, then the voice will be very bright; lung deficiency, then the voice will seem low and weak, so the sound of the high and low depends on whether the lungs are sufficient. 4. Smooth breathing. The “difficult scriptures” pointed out: “exhale heart and lungs, inhale liver and kidneys”, it can be seen that breathing and human heart, lungs, liver and kidneys are very close. Only breathing is not urgent, calm and unhurried, to prove the good function of the internal organs. 5.Strong teeth. Oral hygiene, basically no dental caries and other oral diseases. According to Chinese medicine, “kidney is the main bone”, “teeth are the remainder of the bone”, teeth are part of the bone, and the same source as the bone, so teeth also rely on the kidney essence to enrich. Kidney essence is sufficient, the teeth are strong and complete; essence is insufficient, the teeth are loose, or even fall off. 6, hair moistening. Chinese medicine believes that “the kidney, its Hua in the hair”, “hair for the blood of the surplus”. The hair growth and fall, moist and withered, not only depends on the kidney in the essence of the full nourishment, but also depends on the blood moistening. Healthy people, full of essence and blood, hair moist; on the contrary, when the essence and blood deficiency, the hair is easy to turn white and fall off. 7, waist and legs handy. The waist is the house of the kidneys, kidney deficiency is waist weakness. The knee is the house of tendons, the liver is the main tendons, liver blood deficiency, tendons and veins are not moistened, the limbs flexion and extension is unfavorable. A flexible waist and legs and a relaxed pace are a sign of sufficient kidney essence and strong liver blood. It is recommended that we maintain more than 3 times a week, half an hour each time, so that the muscles, bones and limbs flexible and free. 8, the body shape is appropriate. That is, to maintain a proportionate body shape, not fat and not thin. Standard weight = height (cm) – 100 (female minus 105) (kg). Chinese medicine believes that fat people are more qi deficiency, more phlegm and dampness; thin people are more yin deficiency, more fire. Too thin or too fat is a reflection of sickness, it is easy to suffer from diabetes, cough, stroke and other diseases. 9, good memory. “The brain is the house of the essence”, “the brain is the sea of marrow”, “the kidney is the master of the bone to produce marrow”. The brain is a high convergence of essence and divine, human memory all depend on the function of the brain, the kidney is full of essence, the sea of marrow is nourished, manifested as a strong memory, good understanding. 10, emotional stability. Joy, anger, worry, thought, sadness, fear, fear, the seven emotional changes, reflecting the body’s mental state. If the seven emotions can be expressed normally, the body is healthy, but over-expression of the seven emotions directly injures the five organs: excessive anger hurts the liver, excessive happiness hurts the heart, excessive thinking hurts the spleen, excessive sadness hurts the lungs, and excessive fear hurts the kidneys. Therefore, it is healthy to treat the various emotions that arise in daily life correctly and to be good at regulating them.
