What should I do about the idea that the elderly at home prefer sons to daughters?

Because of the preference for boys, many families around me are like this. Many fathers don't care about their children. In order to please his father, children dress themselves up as boys, and finally feel that they should be boys. What is serious is having a boy, wanting a divorce, and even marrying a second wife, so that the ex-wife can leave home clean. A son was born in a good situation and a daughter was born in a bad situation. Some terrible new families abort their children as soon as they find out it's a girl. After all, the family status of a girl who gives birth to a baby girl and a boy in the countryside may be different. Generally speaking, it is understandable and normal for the elderly to prefer sons to daughters. After all, China's traditional culture has been influenced for thousands of years and will continue. There are several reasons why the elderly prefer boys to girls. First, China people regard death as their death, and attach more importance to the family line. This is caused by China's patriarchal clan system, which began to form in the Zhou Dynasty and is the embodiment of China's sacrificial culture. Two: it is uncomfortable for girls to inherit their career wealth from the elderly. In short, we should give priority to persuasion, open the hearts of the elderly, and let them feel that boys and girls are all the same, all their own flesh and blood, and their own descendants.
