Why do women also prefer boys to girls?

There has been a preference for sons over daughters in China since ancient times. Not only men prefer boys to girls, but also women prefer boys to girls. Although today's society has become a society where everyone is equal and women hold up half the sky, it is said that men and women are equal. Why do so many people prefer boys to girls? If there is no preference for boys over girls, the ratio of men to women will not be unbalanced, resulting in that half of the boys can't find girlfriends now, and they have all become older men. There are still many rural areas that are heavier. If your daughter-in-law can't have a son, show her. If she doesn't have a son, the neighbors will make irresponsible remarks. Some time ago, I saw a news that my son was unfilial and beat up his parents. The story tells that in a particularly remote rural area, the couple gave birth to four daughters before giving birth to a son. They have loved their son very much since they were very young. At that time, the family was particularly poor, and some delicious food was left to my son, never to my daughter, let alone myself. No matter what their son did wrong, they never blamed him. Indulge his bad temper, scrimp and save, and marry his son. My son dislikes his parents less and less as his parents get older. At first, I just scolded my parents, but my son went too far and began to punch and kick his parents. Now his parents are lying in the hospital bed, especially regretting it. All his daughters take care of him. He regretted that he had spoiled his son since childhood. Now some parents are also instilled with this idea and want to have a son. Some women are over 40 years old and risk their lives to have a son. When will the world truly achieve equality between men and women?
