If the number is zero, is it a boy or a girl?

Some parents-to-be are curious to know how to judge whether to have a boy or a girl. In fact, there are many ways to judge the sex of a fetus. Let's have a look. Method 1: Formula: male (year of birth+month of birth+birthday)+female (year of birth+month of birth+birthday)+month of pregnancy-19, mantissa is female, odd number is male, the first half of every leap month follows the previous month, and the second half follows the next month. (biography of Qiang people). Examples: 1967, 15, male life born on February 5th, 1967,1female life born on October 8th, the sex of the pregnant child in May, calculated according to the formula. Then: [(67+12+15)+(67+10+8)+5]-19 = [94+85+5]-19 = Method 2: The method of divination: "Parents live at two years old and take the heart of pregnancy." Chen Gen is a man, but Kun Dui is always a woman. "In the Song Dynasty, the pregnant age of parents was placed in the upper and lower positions, forming a divinatory image, and their men and women were determined according to their yin and yang. Gan Zhen is a boy and Kun Xun is a girl. Parents' age is singular, that is, one year old; It is an even number of paintings, that is, one by one; The month of conception is a single month, that is, one; It's a bimonthly picture, that is, one picture at a time. By combining the three, we can see eight diagrams, in which Yang Bu is male and Yin Bu is female. For example, if the male life 1965 and the female life 1968 are measured, the sex of the child pregnant in March is: male: 1965, which is one; March is Yang's fantastic painting, which is one of them. Female: 1968, even painting. For one after another; Gua is gua.
