Anyway, almost no poor people can afford to read this B line. If the family conditions are not very good, we should be frugal and even have the ability and time to do part-time jobs. If you have money at home, burn money if you want (although many college students are very influential now, there is no need to keep up with the joneses after work.
The above views have no intention of hating the rich.
I am a student in this school.
