If the grades are not good, children who can't go to college can still find a way out. In fact, whether children have a way out has little to do with not going to college. Of course, if you get good grades, you can get into a famous university and find a good job, which is the most correct way out.
But if you can't get into college with poor grades, what I want to say is that you can create a world of your own through your own efforts.
For example, when I was at school, a classmate in our class just didn't study very well. His father once told him that it was useless to go to school. You see, I can earn tens of millions a year now. Even if you don't get into college in the future, I can guarantee that you will follow me and not get into college in the future. It's nothing, as long as you are willing to work hard.
