According to the old calendar, although this budget method belongs to ancient times, it has suddenly set off a wave of fanaticism in the near future.

How to calculate the birth of boys and girls according to the old calendar: please see the picture above. The above age is the nominal age of women, and the date is the month when women are pregnant. The result of giving birth to boys and girls can be obtained through the tripod composed of the woman's age and month! Experts believe that the accurate method to identify the sex of pregnant women's fetus in medicine is to do B-ultrasound, and the chromosome of the fetus can also be detected through DNA blood test, and the sex of the fetus can be identified through fine chromosomes, which has scientific basis and high accuracy.
