First, the trend of modernism makes young people yearn for personal freedom and independence more and more. They will pay more attention to the quality of life and material enjoyment, and have strong personalities. Whether it is material or spiritual, it is not easy for others to do things for themselves, and they are even more unwilling to sacrifice their freedom for marriage, and they will bear too many family responsibilities.
Secondly, with the increasing pace of modern life and social competition, marriage will make people lose more freedom and pay more living costs. The traditional bondage of marriage, the responsibility of marriage and the binding effect of marriage will make many people in marriage become more and more anxious and insecure.
Third, some modern ideas make women more independent, but also make society more tolerant of marriage. Late marriage and non-marriage are increasingly recognized and accepted by society. In other words, people don't need to pay too much life and social cost for not getting married.
Fourthly, the change of ideas, the relative perfection of social pension system and the improvement of medical fertility level also provide more convenient and quick possibilities for fertility problems, pension problems and diversified lifestyles under the unmarried principle. In other words, people don't have to get married reluctantly for living, giving birth and providing for the elderly.
To put it bluntly, everyone's eyes are more and more focused on themselves. Everyone wants to make a profit in marriage, but few people are willing to pay and endure for marriage.
