1. the eyes have a bright gaze, a trace of dull feeling are not, indicating full of energy, blood and vitality, and the function of the viscera and six internal organs is 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. The face is red and rosy. The face is red and yellow and hidden, bright and subtle. The ancients said that “the blood of the 12 meridians and 365 veins are all on the face”, so the color of the face is the “barometer” of the strength and weakness of the qi and blood. If the internal organs function well and the qi and blood are sufficient, the face will be rosy; if the qi and blood are deficient, the face will not be lustrous. The lungs are the main source of Qi, the lungs are sufficient, then the voice will be very bright; lung Qi deficiency, then the voice will seem low and weak, so the voice depends on the adequacy of lung Qi. 4. Breathing smoothly “difficult to Jing” points out: “exhale heart and lungs, inhalation liver and kidney”, it can be seen that breathing and human heart, lungs, liver and kidneys are very close. Only when the breathing is not urgent, calm and unhurried, can 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 master of bone” and “teeth are the remainder of bone”, teeth are part of bone and have the same origin as bone, so teeth also depend on the essence of kidney to enrich. The 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 growth and loss, moistening and withering of hair not only depends on the fullness of the essence in the kidney, but also on the moistening of blood. A healthy person, full of essence and blood, hair moist; on the contrary, when the essence and blood deficiency, hair is easy to turn white and fall off. 7. waist and legs handy waist for the kidney of the house, kidney deficiency is waist weakness. The knee is the house of tendons, the liver is the main tendons, liver blood deficiency, tendons lost 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 you keep exercising more than 3 times a week, half an hour each time, so that the muscles, bones and limbs are flexible and free. 8. Physical matters, 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 more qi deficiency, more phlegm and dampness; thin people 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 genitals”, “the brain is the sea of marrow”, “the kidney is the main bone marrow”. The brain is a high convergence of essence and divine, human memory is all dependent 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; if they are over-expressed, they directly hurt 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.
