There are beautiful older sisters and mediocre younger sisters in the family. Different training methods, different attitudes towards studying, different marriage choices, and different life experiences.
Marriage is a fusion between two people, or even two families, and requires joint efforts and compromise from both parties! It's not something a woman can figure out unilaterally! Is the so-called correct relationship between husband and wife, which is achieved through women's infinite compromise, really the correct relationship between husband and wife? If you have a husband who can't create romance, you really don't desire romance; if you have a husband who doesn't understand you, you really don't need to be considerate; if you have a father who doesn't care about your children, can your children not need to care?
