Is it accurate to give birth to boys and girls?
Many couples predict the baby's sex by comparing the pictures of boys and girls in their leisure time. So are the pictures of boys and girls in Qing Dynasty accurate? There is no scientific basis for the pictures of boys and girls, and it is not allowed to predict the sex of the fetus only by looking at the pictures of boys and girls.
The Picture of Boys and Girls in the Qing Palace is a tool based on the ancient calendar and combined with the theory of Yin-Yang and Five Elements. It has certain reference significance and can be used as a daily reference, but you can't believe it all. In order to scientifically predict boys and girls, the most accurate methods at present are B-ultrasound, amniocentesis or blood sampling to detect DNA.
However, it should be noted that the determination of fetal sex is to prevent the occurrence of sex-linked genetic diseases and achieve the purpose of prenatal and postnatal care. Under normal circumstances, doctors will not give pregnant women a sex test. In fact, boys and girls are all the same. The key is that children can grow up healthily.
Is the Qing palace watch accurate?
Is the Qing palace watch accurate? Many people want to know whether it is accurate to give birth to boys and girls. In fact, this forecast table has no scientific basis. It just summarizes the experience handed down by predecessors for our daily reference. Because the sex of a person is determined by the XY chromosome in the germ cell.
It is the male sex chromosome that determines the sex of the fetus. There are 23 pairs of chromosomes in human cells, 22 of which are XX, and the rest of the sex chromosomes vary according to gender. The male sex chromosome is XY, and the female sex chromosome is XX. X and Y in the sex chromosome are the key to determine the sex of the fetus. When sperm and egg cells are combined, if Y chromosome and X chromosome are combined, the fetus is a boy and if XX is a girl.
It can be seen that the birth of boys and girls has nothing to do with the date. It is impossible to infer the sex of the fetus in Qing Dynasty. Women can be used as entertainment, but don't take it seriously.

The picture says that all the things about having a boy are hidden in the fetal dream. Have you decided to have a boy and a girl?
It is not a woman's decision to have boys and girls, but mainly the man's sex chromosome. Women of normal reproductive age generally ovulate only one egg every month, and the sex chromosomes of eggs are all X chromosomes, while the sex chromosomes of men are in sperm, and there are two types:
1, when sperm with X chromosome in male body is combined with female egg, fertilized egg is XX sex chromosome and fetus is female;
2. When sperm with Y chromosome in male body is combined with female egg, the fertilized egg is XY sex chromosome and the fetus is male.
As for some popular sayings, such as "a sharp belly gives birth to a boy, a round belly gives birth to a girl", "an ugly boy gives birth to a beautiful girl", "a boy with swollen feet and a spicy girl with swollen feet" and "a sour child", there may be some truth, but none of them have been scientifically proved, and some people have come true. On the contrary, because it is a 50-50 chance to have boys and girls, it is not appropriate to be superstitious about all kinds of anecdotal statements.
