First of all, let your brother think about his ideals and goals in this life. If it's for money, power and status, what's the difference between you coming out of Nantah and you coming out of Peking University? Going abroad to study for a doctorate is to sell five years of youth to the boss, and the income is not high. No matter how beautiful it is at home, you can start from scratch abroad. Can top students tolerate this gap? Then there are all kinds of inevitable trivial issues such as racial discrimination. In my opinion, the more highly educated people are, the more arrogant, subjective and extreme they are, and the lower their EQ is. There are many such people in America, and they are also very lonely and vulnerable groups.
Looking for a job after graduation? It is difficult to work in the American economic crisis, and it is difficult for Americans to find it themselves. Then foreigners call it a small number. If you don't have a car, you can say that you are isolated from the world. If you are shut up in the corner like most China people who go abroad, it is estimated that suicide is possible, then your circle will always be only China people. China people bully each other the most, right and wrong the most.
Then if you love your major and go abroad for this major, I support it. Otherwise, you will work hard and it is impossible to work or study in America. And it's easy to get confused. Many people don't know why they want to come abroad. It's just that all the top students in the class have gone out, and he will come out, too. However, if you want to be a professional, you should not study in China at all. Just come out and be an undergraduate. If you have a goal, can take care of yourself and have a good emotional intelligence, it is no problem to come out early.
The advantage of coming out is that you can see the world clearly and the people in China and China clearly. It doesn't matter what you read if it's just for a better living environment or conditions. Working as an illegal worker in a restaurant can still get more than 10 thousand RMB a month.
So, let him think it over before deciding. It's up to him to do a lot of things a year or to waste them by repeating them. Don't squeeze your head and complain that foreign countries are not as good as domestic ones. Because some aspects are really not good, especially for China people.
I hope it helps.
