A patriarchal sentence with a mother-in-law

For example, "our family is a single biography of several generations." If your mother-in-law keeps telling you that their family is the only child before the baby is born. Then in your mother-in-law's heart, it is very important to have a boy. In fact, she also told you from the side that she must have grandchildren, and her family style must be passed down. So if your mother-in-law said this to you, it means that she has a preference for boys. Because she had a son at that time, she felt that her daughter-in-law needed to carry on the family line.
