Giving birth to boys and girls is a matter for both husband and wife, so the appearance should also be judged by men and women. The basic principle of physiognomy is "depending on the heart", and vice versa. We can see the fate of boys and girls from the following aspects: Men mainly look at eyebrows. Because "Tibet is better than bones, and now Yumei is better." A moist man with thick eyebrows, dark hair and long face is sure to be energetic for a long time, and the probability of having a boy is above 60%. Dr. Zheng warned that if all hair is "firm" like eyebrows, the probability will rise to 80% to 90%, because "kidney failure leads to miscarriage, and kidney deficiency leads to long hair." Women reveal fertility information mainly by looking at their mouths, lips and their adjacent parts. If a woman's lips are purple, dim, white or too bright, she will give birth to a baby girl; if her lips are rosy, she will give birth to a baby boy. Physiologically, a woman's upper lip is dominated by the large intestine meridian, and ren meridian has the function of pregnancy and childbirth; In the center of the upper lip, the function and configuration of the bladder can be observed; People with lip bead have concentrated feelings and strong bladders; As for the triangular relationship between laws and people and the inner edge of nostrils, we can observe the strength and sexual ability of reproductive organs. But if men and women come to the opposite conclusion from their faces, there is yin-yang theory in numerology as the basis. According to the Yin-Yang theory of numerology, people concerned remind friends that both men and women should be calm and carefree. Specifically: 1, if a man's eyebrows, hair, pubic hair and other hairs show that he is a man, while a woman's lips show that he is a woman, then he is a woman. 2. If a man's hair shows that he is a man, he is also a woman. 3. He is "right" only when both men and women show signs of being male, otherwise, he is "negative" and "negative". 4. In addition, eyebrows, lips and other hairs will change with time and the change of houses (houses, offices), which can be described as a temporary change. 5, before preparing to make a person, you can adjust the house feng shui and health, so that the husband and wife can look good at the same time. Usually, the color changes of men and women appear in a solar term. Finally, Dr. Zheng solemnly quoted the words of the great chairman: Times have changed, and men and women are the same. What gay men can do, so can lesbians. It has been proved that the number of sperm in men will decrease with age, so the probability of giving birth to girls is particularly high. Similarly, the older a woman is, due to the influence of age, the alkaline secretion in the uterus will decrease year by year, and the chance of giving birth to a girl will greatly increase. Therefore, it is an indisputable fact that older couples are more likely to have daughters than younger couples. Occupational factors According to statistical reports, if men are drivers who drive for a long time (such as taxi drivers and truck drivers), flight attendants or pilots, anesthesiologists and divers who work in the deep sea, the chances of giving birth to girls are particularly high. This is because? Pills are subjected to drastic changes in high temperature, air pressure or water pressure, or too much toxic anesthetic gas is inhaled, resulting in premature death of Y sperm with less vitality, which leads to more chances of giving birth to girls. According to years of research and statistics, it is proved that the pH of food really affects the chances of having boys and girls. If you want to have a boy, women should eat more alkaline food and men should have a balanced diet; If you want to conceive a girl, women should avoid eating too much alkaline food, but don't eat too much acidic food, so as not to affect their health. Both men and women should have a balanced diet. Alkaline foods include beans (pods or green beans), vegetables, fruits (except bananas, plums and processed fruits), fresh milk, grains (such as corn), tea, kelp, seaweed, yeast, iodine, calcium and vitamin D, while acidic foods include all meat, fish, dairy products (such as cream, ice cream, cheese and flavored milk) and rice except fresh milk. Stress factors Long-term stress in men will reduce the number of sperm; Women who are too nervous will have a strong acidic environment, which is not conducive to the survival of Y sperm. Therefore, people with too much work pressure and great pressure to have children are particularly prone to have girls. If you want to have a boy, don't be too stressed, just relax. Men wear tights. If men usually wear tights, the scrotum temperature will rise, resulting in a decrease in sperm count. Y sperm that gives birth to a boy will die first, which will greatly increase the chances of giving birth to a girl, and may also be temporarily infertile. If you want to have a boy, you must prevent the scrotum from overheating, so men should pay special attention not to wear tights. British scientists have found that pregnant women who are vegetarian are more likely to have daughters. Ms. Hudson, the scholar who presided over the study, said that although there is no other study on the influence of pregnant women's diet on the sex of their children, this study still shows that the vegetarian diet of pregnant women has a direct impact on the sex of their children. The study by Nottingham University found that the ratio of male to female babies in Britain is 106 100, but the ratio of male to female babies born to vegetarian pregnant women is 85 100. This data shows that pregnant women who are vegetarian are more likely to have daughters. Expert: The most important thing is that the sex ratio remains unchanged. On the issue of human reproduction, there is naturally a very beautiful phenomenon that is very consistent with human development. That is, the sex ratio between men and women has always been relatively constant, and the population of men and women is equal, which is of great significance to maintaining social development and stability and to the reproduction and prosperity of mankind. Some of the above-mentioned related factors are only theoretical inferences, and some are only associative guesses. They have not been studied systematically, comprehensively and with large samples, so they are still unscientific.
