Let's start with the latest one. Roughly speaking, since 20 12, there have been 20 starlets in China. There are Li Lian, Xiao S, Andy Lau and Ada Choi, former Hong Kong sisters Cao Minli, Lin Xilei, Li XiaoLu, Athena Chu, Wen Songxian and Sonija Kwok, former "super girl" Feng Jiamei, famous directors Wu Shixian, Su Yan, Wu Yanzu and Tang Yingying, Taiwanese supermodel Lin Jiaqi, supermodel Jiang Yi, etc. Among them, more than two-thirds of the stars are rich, like Cai Shaofen or Lian Sheng. Let's take another look. Some celebrities seem to have a special daughter relationship. Jet Li has four daughters, two of whom were born to two wives. Gao Lingfeng got married and divorced, then got married and divorced, and got married and divorced three times. * * * has six children, five of whom are daughters. Chingmy Yau, who entered the entertainment industry as a Miss Hongkong and has been in the film industry for many years, has three children, all of whom are daughters. Christy Chung, a sexy actress, had a daughter before marriage and two after marriage. Brigitte Lin has given birth to two daughters for her husband, but she has already given birth to a daughter with her ex-wife. Xiao S has given birth to three daughters now, and I don't know if she will continue to give birth. It has also been found that some female stars who have been or are still single mothers have given birth to daughters, such as Faye Wong, Sandy Lam, Guan Shuyi, Huang Peixia, Wu Qili, Feifei and Alyssa Chia. Most male stars who have played Qiong Yao's dramas have daughters, such as Ma Jingtao, Xu Nailin, Lin Ruiyang, Chung Hua Tou, Ben Lee and Vincent Chiao. Why is this happening? Should we really accept the old saying that "a rich family has a rich daughter, but a poor boy"? A closer look at these male and female stars reveals several reasons. 1, people with professional backgrounds find that there are more teachers and daughters in the Institute of Physical Education. The statement that athletes are prone to have girls has certain scientific basis, but it is not absolute. Because sperm containing Y chromosome is more active in alkaline environment, it is easier to have boys. Sperm containing X chromosome is more active in acidic environment, and it is easier to give birth to girls. Athletes exercise a lot, and their muscles produce a lot of lactic acid, which leads to a lot of acidic substances deposition. In addition, athletes consume a lot of energy, most of which is acidic, which makes the whole body acidic. You will find that many male stars are martial arts majors and female stars are dance majors. For example, Max Zhang, the husband of Jet Li and Ada Choi, has been under high pressure and a lot of exercise for a long time, which makes her body acidic, so it is easy to have a daughter. According to male occupation statistics, drivers, pilots, divers, etc. Those who drive for a long time have a particularly high probability of giving birth to girls. This is because the testis is strongly changed by high temperature, air pressure or water pressure, which leads to the premature death of Y sperm with low vitality, which leads to more chances of giving birth to girls. 2, often eat vegetarian British scientists found that the ratio of sons and daughters born to vegetarian pregnant women is 85: 100, which means that vegetarian pregnant women are more likely to have daughters. Although there is no other research on the influence of pregnant women's diet on children's gender, the data of this study show that pregnant women's vegetarianism does have an influence on children's gender. Statistics show that the pH of food will affect the chances of having boys and girls. Women's vaginas are generally acidic. If alkaline substances are secreted during orgasm, it is more suitable for Y sperm to survive. Diet control is to divide food into acidic, alkaline and neutral foods. Men eat acidic food and women eat alkaline food, which helps to have boys. Men eat more alkaline food, and women eat more acidic food, which is more beneficial to girls. Such as tomatoes, oranges, strawberries, grapes, pineapples, apples and other sour fruits are acidic foods. Such as mung beans, soybeans, red beans, tofu and so on. Vegetables such as vegetables, lettuce, potatoes, bamboo shoots, onions, mushrooms, cauliflower, kelp, bananas, watermelons, loquat and other fruits and wheat flour products, milk, tea and so on. , all belong to alkaline food. Stars, especially female stars, tend to lose weight in order to look good on camera, keep their skin smooth and delicate and graceful, so they eat more acidic fruits. Boys will eat more vegetables while keeping healthy and losing weight. So stars are more likely to have daughters. 3, work pressure to see the star aura shine, but the hardships under the stage are equally eye-catching. They often work under high pressure, filming during the day, broadcasting at night, practicing songs during the day and dancing at night. They were in Hainan yesterday and they are in Beijing today. So some stars will disappear when they struggle to a certain extent, because they want to relax and have a rest, so they temporarily leave the public eye. Let's go back to the topic of having boys and girls. Long-term mental 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. This can understand why there are so many star daughters. 4. The sperm count of men who marry late and have children late will decrease with age, so older men are more likely to have daughters. Similarly, the older a woman is, due to the influence of age, the alkaline secretion in the uterus will gradually decrease, and the chance of having a daughter will greatly increase. Therefore, older couples are more likely to have daughters than younger couples. Stars For the sake of performing arts, many stars get married late. Most female stars can be called older women. The best pregnancy age for women is 25-30 years old, and the best pregnancy age for men is 30-35 years old. Babies born in this period are also of the best quality. 5, genetic inheritance People often say that twins have inheritance. For example, I have a friend whose mother and uncle are twins, his grandmother and uncle are twins, and he and his sister are twins. What is heredity? The similarity of characteristics between parents and offspring is called heredity. Human cells (including sperm cells-sperm; Egg-egg), there is a small body with special structure, called chromosome. There are many genetic materials arranged in sequence on chromosomes, which are called genes. The chemical composition of a gene is deoxyribonucleic acid (DNA). It is like a video tape, which records all the characteristics of parents and skillfully passes them on to the next generation. Heredity is controlled by genes. Everyone knows that Xiao S and Da S are sisters, and they also have a sister, which means that their generation of Xiao S has three daughters. So it is not surprising that Xiao S has three daughters in a row. 6. For other reasons, some people say that a father with a delicate mind is more likely to have a daughter; Generous, careless, careless men are prone to have sons, especially the first child. This can also explain why the actor who plays Qiong Yao gave birth to a daughter. In addition, in the current living and working environment, electromagnetic wave pollution is more popular, male chromosomes are weak in electromagnetic wave resistance, so it is not easy to survive, and female chromosomes are tough, so they survive. The above reasons and explanations are just small series, which are not necessarily accurate. I hope there will be scientific investigation results to solve our doubts.
