You think boys are preferred to girls, right?

Morally speaking, it should be wrong, but in reality, it is right. For example, our rural families are very poor. We have a family there, and her daughter studies very well, so her daughter goes to graduate school all the way (going to school costs a lot of money, which rural families simply can't afford. Others have built a building, and his family still lives in a tile house. Many people in the same village buy houses in the county, and his family has no money to buy them. My daughter graduated last year and married in another province. When she got married, her daughter was pregnant. Now my son is almost thirty, and even a suite can't be bought at home. He can't marry a wife. The old couple didn't mention how his daughter was. They pull a long face all day, waiting for someone to tell him that his daughter-in-law is farting, and everyone in the village laughs at his family. No matter how good the daughter is, it belongs to others. No matter how bad the sons are, they are their own. This is the reality, which is not a backward concept at all. Who is it?
