In life, people find that girls develop a little earlier than boys, such as: learning to speak, learn to walk, learn knowledge, understand things, and many other aspects, always perform better. This phenomenon has been described in ancient times: “Su Wen – Shang Gu Tian Zhen Lun” has a paragraph discussing the growth and development cycle of men and women: “Women seven years old, the kidneys are strong, the teeth more hair long; two seven and the day of sebum to, Ren vein through, Tai Chong vein Sheng, the moon to the time, so there are children; three seven kidney gas average, so the real teeth and long pole; four seven tendons and bones firm, hair long pole, the body is strong; five seven Yang Ming vein Yang Ming pulse. The body is strong; five seven Yangming pulse failure, the face began to scorch, hair began to fall; six seven three Yang pulse failure in the upper, the face are scorched, hair began to white; seven seven Ren pulse deficiency, Taichong pulse failure less, the days of sebum exhaustion, the ground is not accessible, so the form is bad and childless. Husband eight years old kidney qi real, long hair and teeth more; two eight kidney qi Sheng, the day sebum to, essence overflow write, Yin and Yang, so can have children; three eight kidney qi average, tendons and bones strong, so the real teeth and long pole; four eight tendons and bones bloom, muscle full strong; five eight kidney qi failure, hair fall teeth haggard; six eight Yang qi failure on the top, face scorched, hair and temples white; seven eight liver qi failure, tendons can not move; eight eight day sebum exhausted, less essence, kidney collection failure, the form is bad and extreme. Then the teeth hair go.” Why do men take eight years as the cycle, and women take seven years as the cycle? Later generations of doctors such as Wang Bing, Zhang Jiebin, etc. believe that men less Yang Qi, so with the number of Shao Yin eight; women for Shao Yin Qi, so with the number of Shao Yang seven. Tang Zonghai that seven, eight for the number of Luoshu, Luoshu with the eight trigrams of King Wen, against the number of seven, the number of burgundy for eight, against the girl, then the number of seven; burgundy for young men, so the number of eight. From the actual situation of men and women growth and development, men about sixteen years old (two eight), women about fourteen years old (two seven) sexual maturity, men about sixty-four years old (eight eight), women about forty-nine years old (seven seven) reproductive decline, it can be seen that men to eight years old for the cycle, women to seven years old for the cycle, there is some justification. From a biogenetic point of view, the female sex chromosome is XX, the male sex chromosome is XY, that is, men are about one-eighth less than women sex chromosomes, is it because of this little difference, resulting in men in growth and development slightly lagging behind women? Let’s try to do this scenario: the seven legs of the male “XY” chromosome are one less than the eight legs of the female “XX” chromosome, if no other factors interfere, the male growth and development is one eighth slower than the female, the female seven years of development The male needs eight years to complete, and so on, the female 14 years male needs 16 years, … Of course, human development is not only affected by sex chromosomes, but also by autosomes and other multiple factors, so the actual situation is much more complex. Another difference between men and women in traditional culture is that men dominate the yang, for the sky, for the dry; women dominate the yin, for the earth, for the kun. Many people think that this is a feudal society, the idea of inequality between men and women, in fact, this also contains the physiological and psychological aspects of the truth: men are in a disadvantageous position in terms of sex chromosomes, lagging behind the development of women, resulting in a sense of psychological inferiority, will try to do something to get people’s recognition as compensation, which is one of the lifelong subject of men. On the other hand, from the psychosexual point of view, male sexuality is easily affected by tension, anxiety, only without any interference and threat to complete the sexual act, while women are relatively less sensitive to this point, male superiority model is conducive to a harmonious sex life, so there will be “big heroes and small beauties” said. Modern society, gender equality, should be social status, rights and treatment of equality, if you do not take into account the difference between men and women, the concept of equality between men and women mechanically applied to the mode of interaction between husband and wife, men’s inferiority complex in married life can not be to the effective relief, will escape from married life, trying to bet on other aspects, indulge in or money, or career, or power, or gambling, or art, or games, or The company’s main goal is to provide a good solution to the problem.
