Can Zhouyi freely calculate whether boys and girls are allowed? Single and bimonthly boys and girls form

In the past, medicine was not very developed, and there was no scientific method to determine whether the baby in a pregnant woman's belly was a boy or a girl, so there were many indigenous methods to test men and women. Although it is now possible to judge the sex of the fetus through examination, it is forbidden by law to identify the sex of the fetus, so some pregnant women will try some indigenous methods to guess the sex of the fetus. So does Zhouyi allow free calculation of boys and girls, and does it allow single and twin boys and girls?

I believe many people have heard of Zhouyi, which has existed since ancient times and is also the first of the Five Classics. Coupled with its complete preservation, there is the Zhouyi that future generations can see. The content of giving birth to boys and girls in Zhouyi is also involved. According to the calculation method of Zhouyi, the table of boys and girls in Zhouyi came out. But this method is only a kind of calculation, with low accuracy and unscientific. Prospective parents can try it as an interest, but don't blindly believe it.

In addition, the method of detecting fetal sex in the form of singleton and twin boys and girls has been confirmed by some pregnant women, and it is said that the accuracy is very high. The calculation method is one month a year, two years and two months, which means you are pregnant with a girl. If you are one year old and two months old, a boy will be born in the first half of the month. Note here that the month is the first day of the last menstrual period before pregnancy, and the age is an imaginary age starting from the first day of the last menstrual period before pregnancy. The so-called morphological judgment of single and twin boys and girls means that boys and girls have no scientific explanation and do not know the accuracy. You are not advised to be too superstitious.

In short, it is a question of probability for expectant mothers to have boys and girls. There is no scientific proof that men and women can be tested by the free calculation of Zhouyi and the form of single and double months, and medically speaking, the probability of giving birth to boys and girls is 50/50.
