Folk methods for calculating boys and girls

Method 1: The diagram of the Qing Palace of giving birth to boys and girls is a table for predicting the birth of boys and girls, which is calculated according to the Zhouyi and the formulas of Yin and Yang, Five Elements and Eight Diagrams. The rumor of the Qing palace map is a prediction of the birth of boys and girls during the Qing palace period.

The prediction object of the comparison table for boys and girls in Tingsheng is mainly women, which is calculated according to the age and pregnancy month of women. Because the comparison table is made according to the laws of ancient heavenly stems and earthly branches, traditional calculation methods are needed in calculation. For example, the age should be the date of birth of a woman plus 9 months of imaginary years in the lunar calendar, and the month of pregnancy should be based on the lunar month. It originated from Zhouyi and was calculated according to the formula of Yin and Yang five lines of gossip. It has a history of about 300 years and was run by eunuchs of past dynasties. In this table, 1~ 12 represents the month of pregnancy, 18~45 represents the female age, and the information exchange table for boys and girls is calculated on the basis of virtual age.

Method 2: Calculate the formula for men and women in 7749: 7749 (49), ask when the mother has it (plus the lunar month of ovulation month), subtract the mother's age (minus the nominal age), and add 19. Divide by 2, (don't round, just look at the number before the decimal point) even little princess, odd little prince. All ages and months here refer to the lunar calendar date.

For example, 1972 was born, and August 8, 2002 is a holiday, so the ovulation period is around August 22, which is July of the lunar calendar 14.

The calculation method is as follows: 49+7-31+19-44/2 = 22. I am pregnant with a girl this month.

In addition, I don't know how to calculate this formula if the ovulation period is at the beginning or end of the month, or within a month. There is no way to decorate the moon. At the beginning and end of the month, it is not accurate unless you know exactly when you were conceived.

Method 3: the formula mantissa calculation method for men and women is as follows: male date of birth+female date of birth+pregnancy month-19= mantissa of the obtained number, with odd numbers for men and even numbers for women. The month, year and day in this algorithm are all required to be lunar months.

Method 4: Algorithm for calculating fetus through bones: There are three lines to be calculated. The first line is Bao Da's imaginary age as of the month of pregnancy; The last line is the nominal age of Ma Bao's pregnant month. The middle line is the lunar month, and Bao's father and mother are pregnant in the same room.

Draw a picture that matches you according to the drawing method at the top of the picture, and two lines at the bottom of the picture. The first row of typesetting pictures are boys and the second row is girls.

Method 5: Hot and sour girl? Hot and sour girl? Giving birth to boys and girls is one of the most widely circulated rumors. Judging the sex of the baby in the belly according to the changes in the eating habits of the expectant mother after pregnancy. If you like sour food, you will have a boy; If you like spicy food, you will have a girl.

This statement is too inaccurate, because pregnant women's loss of appetite, sensitivity to odor, acidophilia or spicy taste, and even want to eat some foods that they don't like at ordinary times are all normal physiological reactions of pregnancy, because endocrine activities change after pregnancy, and the placenta secretes chorionic gonadotropin. This hormone can inhibit gastric acid secretion, reduce gastric acid secretion, thus reducing the activity of digestive enzymes, affecting appetite and digestive function, regardless of fetal sex.

Method 6: Look at the shape of B-ultrasound gestational sac. After 6 ~ 8 weeks of pregnancy, the expectant mother should have the first B-ultrasound to determine whether there is a good pregnancy and gestational age in the uterus. The shape of the gestational sac is used by many expectant mothers to judge the sex of the baby. Generally speaking, if the gestational sac is eggplant-shaped, or the data of one gestational sac is twice as high as that of the other two, then it is a male baby. If the gestational sac is round and the three numbers of the gestational sac are in sharp contrast, then it is a female baby. This time, my two babies met, but according to other mothers' feedback, there are exceptions.

Method 7: Look at the belly of the mother who gave birth to a girl. The lower end is mostly inverted trapezoid with prominent lines, which can almost be called angular. The more obvious the trapezoid, the higher the accuracy. The lower part of the boy's mother's stomach is smooth and full, and there is no such prominent line. But this situation is not very absolute. Here are the bellies of girls and boys' mothers.
