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)+pregnant month-19, mantissa is female, odd number is male, the first half of each leap month follows the last month, and the second half follows the next month. (biography of Qiang people). Example: male life born on February 5th 1967, 15 and female life born on October 8th 1967. The sex of pregnant children in May is 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 the age of two and take it with the heart of the moon." Chen Gen is a man, but Kun is always a woman. "In the song, the pregnant age of parents is placed in the upper and lower positions, forming a divinatory image, and their men and women are determined according to their yin and yang. What a boy! Kun-hoon is a girl. The age of parents is singular, that is, one year old; It is an even number of paintings, that is, one painting at a time; The month of conception is a single month, that is, one month; It is a bimonthly painting, that is, one painting at a time. Combining the three, we can see gossip, in which yang divination is male and yin divination is female. For example, if the life expectancy of men is 1965 and that of women is 1968, the sex of the child pregnant in March is: male: 1965, which is one; March is a painting by Yang, which is one of them. Female: 1968, even painting. For one after another; Divination is a kind of divination symbol.
