Are Americans friendly to immigrant students from China? Is it lonely and exclusive to go out?

Language is a slow effort. Listen and watch more, and you will understand slowly. Actually, foreigners are very friendly. Seriously, it's much better than people in China. China people are enthusiastic on the surface, but indifferent on the inside. Foreigners are the opposite. In a word, after you go, you don't want to live in China. There are many things that cannot be compared.
