silence is golden. Good and bad are our own efforts. Mixing well may not be satisfactory in all aspects! If you don't mix well, maybe everything will be fine. If you want to mix well, work hard. Everyone wants to get along. Your classmates may not do very well either.
If I really mix my views well, I won't flatter myself and make others sad in front of people who don't mix well or have no money. I don't think such people can mix well.
