Why do you feel that you meet more wonderful China classmates or friends when you study abroad?

Not all people go abroad because their families are rich. Many people spend their savings at home to study. Maybe four years' tuition costs five or six years' deposit. Therefore, in the same school, there are likely to be students who are vain, love to take advantage, petty and stab in the back. In the final analysis, their parents were too busy or poor to support them, and they were reluctant to spend money. Thinking about money every day will become like this.
