In my opinion, getting married too early has many disadvantages. It is said that every family has its own problems, so why start a family at the age when freedom is most needed? I have to put such a difficult book on myself. In fact, what I want to say is that marriage can make a person more mature, but it will also bring a lot of pressure and unexpected resistance to a person, especially to a man.
For example, if a young man wants to start a business, but he doesn't have much money at hand, if he is not married, he doesn't have to consider his wife or even his children, so he has more opportunities to realize his dreams and more imagination now. If he gets married, many things will be restricted, and he will definitely consider his wife, because he dare not risk his family, and he will consider many problems.
Also, just graduated from college, why not leave some time for yourself to go out for a walk? The world is so big, how can I not travel? If you get married immediately after graduation, there are not many opportunities to go out to play, so I don't think it is good to get married immediately after graduation.
