1, innate endowment “two gods fighting each other, combined and formed.” Therefore, the surplus and deficit of the parents’ reproductive essence and physical characteristics determine the thickness and strength of the offspring’s endowment and affect their physique, and the bias of yin and yang in the parents’ body and the differences in functional activities can cause the offspring to have the same tendency, according to Wan Quan of the Ming Dynasty, “The child and the parents are one and divided.” The strengths and weaknesses of the parents’ form and essence and blood have caused differences in the offspring’s endowment, manifesting differences in physique, such as physical strength, fatness, rigidity, length, skin color, character, temperament, and even congenital physical defects and hereditary diseases, such as chicken breast, turtle back, epilepsy, asthma, etc. 2, age factors With the change of age, the formation and evolution of male and female physique, can be divided into five stages: (1) from birth to adolescence, is the stage of physical maturity, stereotypes, the basic physique stereotypes at the end of puberty. (2) puberty to about 35 years of age, the female physique often undergoes more obvious changes, and most of them are shifted to pathological physique, some pathological state. Relatively speaking, the changes in men during this period are not very significant. (3) 35 years of age to menopause before the men and women, are in the prime of life, most of the physical changes are more moderate. (4) Women at the age of 50 and men at the age of 55-60 enter menopause, and their physique changes significantly because of the gradual depletion of Tianjiu and the decay of essence and blood. (5) In the old age after menopause, the physique of men and women becomes increasingly deficient and sexualized, often with deficiency and phlegm and stasis. Children are vigorous and their essence and yin and yang grow vigorously, so they are called “pure yang bodies”. However, its essence and yin and yang are not fully mature, so it is also called “infantile yin and yang”. The physical characteristics of children were summarized by previous generations as follows: the internal organs are delicate, the shape is not yet full, easy to deficiency, easy to cold, easy to heat. In the Ming Dynasty, Wan Quan’s “Secret of Infant Care – General Theory of the Treatment of the Five Viscera” pointed out that the physical characteristics of children are “the liver has a surplus of the five viscera, the spleen is often deficient and the kidneys are often deficient, the heart is hot as the fire with the liver, and the delicate lungs are not easily healed by injury.” Adults are generally full of essence, blood and fluids, the function of the internal organs is strong and healthy, the type of physique has basically set, generally speaking more stable. Older people due to the physiological decline of internal organ function activities, the physique often shows the gradual decline of essence, yin and yang imbalance, visceral function, metabolic slowdown, qi and blood stagnation and other characteristics. 3, gender differences Due to the differences between men and women in genetic traits, body shape, visceral structure and other aspects, the corresponding physiological functions, psychological characteristics are also different, so there are gender differences in the physique. Men are Yang, women are Yin. Men are more endowed with masculine energy, organ function is strong, strong and sturdy, capable of heavy physical and mental labor, personality more extroverted, rough, open-minded; women are more endowed with feminine energy, organ function is weak, small and slim, personality more introverted, like quiet, delicate, sentimental. Men with the kidney as the innate, to the essence, gas as the basic; women with the liver as the innate, to the blood as the basic. Men use more qi, so qi is often insufficient; women use more blood, so blood is often insufficient. Men’s diseases are mostly in the qi part, women’s diseases are mostly in the blood part. Men’s diseases are mostly caused by injury to the essence and depletion of Qi, women’s diseases are mostly caused by injury to the blood. In addition, women due to menstruation, belt, fetus, birth, breast and other special physiological processes, as well as menstruation, pregnancy and puerperium changes in the body. When the menstrual period, the body produces obvious cyclical changes, so Chinese medicine has a menstrual cold hot blood room and other monographs; pregnancy due to the needs of fetal growth and development, the puerperium due to the impact of childbirth, nursing, the maternal body systems produce a series of adaptive reactions, so there is a “pregnant women should be cool, after the birth of warm” said. The “Golden Knot” summarizes the characteristics of the postpartum physique as follows: “the new blood deficiency, sweating, like the stroke, so that the disease spasms; the loss of blood and sweat, cold, so that depression; the loss of fluids, stomach dryness, so the stool is difficult.” However, the male physique also has shortcomings, men tend to be more sensitive to disease than women, more susceptible to disease, and often more serious lesions, mortality is also higher. 4, the dietary factors of the internal organs of the essence of yin and yang, need five flavors of yin and yang and together. Long-term dietary habits and fixed quality of dietary varieties, over time can affect the physique due to changes in certain components of the body, such as increases and decreases. If the diet is insufficient, affecting the production of essence, blood and fluids, can make the body weak; diet bias, so that the lack or excess of certain substances in the body, can cause the human organ gas bias Sheng or bias decline, the formation of bias tendency of the physique, and even become the cause of certain diseases. Such as fatty, sweet and thick taste can help dampness and phlegm, forming phlegm-damp physique; addicted to spicy food is easy to fire burning Jin, forming a Yin deficiency fire physique; over-eating into the blood sad, forming a weak heart physique; over-eating cold and cold will damage the spleen and stomach, resulting in a weak spleen temper physique; excessive diet, long damage to the spleen and stomach, can be formed in the form of Sheng Qi deficiency physique; crave alcoholic wine and wine, moisture and heat in the middle, easy to hurt the liver and spleen. Reasonable dietary structure, scientific eating habits, proper nutrition level, can maintain and promote the normal growth and development of the body, so that the vitality of the spirit, the function of the internal organs in harmony, phlegm and dampness is not born, yin and yang, the secret, strong physique. 5, labor and physical exercise moderate labor or physical exercise, can make the muscles and bones strong, joints, smooth qi, qi and blood harmonization, organ function; appropriate rest, is conducive to eliminating fatigue, restore physical and mental strength, to maintain the normal functional activities of the body. The combination of work and rest is conducive to the physical and mental health of the human body and to maintain good health. But excessive work, it is easy to damage the bones and muscles, consume blood and Qi, resulting in a lack of vital energy of the internal organs, weakened function, the formation of deficiency physique. 6, the emotion factor Emotion, general refers to the happiness, anger, worry, sadness, fear and other mental activities, is the body’s normal response to external objective stimuli, reflecting the body’s ability to adapt to changes in the natural and social environment. The generation and maintenance of emotion and will activities depend on the functional activities of the internal organs, with the material basis of the internal essence and yin and yang. Changes in the “seven emotions” can affect the body’s constitution by influencing the changes in the internal organs. Therefore, the spirit of emotions, and the spirit of harmony. Emotion and regulation, then the qi and blood regulation smooth, the internal organs function in harmony, the body is strong. On the contrary, long-term strong emotional stimulation, persistent and unremitting emotional activities, more than the body’s physiological regulation, can lead to a deficiency or disorder of the internal organs, causing adverse effects on the physique. The common qi-depression physique is mostly caused by this. Qi depression into fire, injury Yin burning blood, but also can lead to Yang hot physique or Yin deficiency physique. Qi stagnation can also form blood stasis type physique. For example, if you are depressed and irritable, you are prone to dizziness and stroke; if you are sad and depressed for a long time, you are prone to cancer. Therefore, maintaining a good mental state is very beneficial to physical health. 7. Geographical factors Different regions or areas have different geographical characteristics, including the physical properties of the earth’s crust, the chemical composition of the soil, the nature of soil and water, the production of goods and climatic conditions. These characteristics affect the dietary structure, living conditions, lifestyle, social folklore, etc. of people in different regions, thus restricting the formation and development of the morphological structure, physiological functions and psychological behavior characteristics of different people living in different regions. At the same time, human beings have dynamic adaptability. Due to different natural environmental conditions, human beings have formed physical characteristics under different natural conditions with self-regulation mechanisms and adaptation methods. The Treatise on the Sources of Medicine – Five Directions for Different Treatments states, “People are endowed with the qi of heaven and earth to be born, so their qi varies everywhere.” Generally speaking, people in the north are more robust, coupled with dense; people in the southeast are more thin, coupled with lax; people in the coastal lakes, more wet and more phlegm. Living in a cold and wet environment, easy to form a Yin Sheng physique or wet Sheng physique. 8, the disease needle medicine and other factors Disease is an important factor to promote the change of physique. Generally speaking, disease change physique is more to the adverse side of the change, such as a major disease, after a long illness, often make the physique weak; certain chronic diseases (such as chronic nephritis, tuberculosis, etc.) prolonged for a long time, the patient’s physique is prone to show a certain specificity. However, infection with evil qi and certain diseases (e.g. measles, mumps) will also make the body have the corresponding immunity, so that the patient will not suffer from this disease for life. In addition, the type of physique formed by disease damage is also related to the changes in the disease, such as chronic hepatitis in the early stage of the qi stagnation type of physique, with the development of the disease can be changed to blood stasis type, yin deficiency type and other different types of physique. It can be seen that the physical and disease factors are often mutual cause and effect. Drugs have different sexual characteristics, acupuncture also has the corresponding effect of tonic and diarrhea, can adjust the internal organs of the essence of yin and yang and meridian qi and blood bias, used properly, will receive the effect of remedial bias to save harm, so that the pathological physique back to normal; improper use, or acupuncture and medicine misuse, will aggravate the damage to the physique, so that the physique from strong to decay, from strong to weak.
