When I went to Hollywood, I offended a foreigner, which made me feel that the foreigner's personality was really strange. Can someone explain it to me?

Your mood at that time was understandable. However, forgive me for saying something unpleasant. Maybe your English is too poor. So he misunderstood. In fact, as long as you calm down, you can even row a boat. ...

Perhaps another reason is that there are more and more China people traveling abroad recently, but most of them are not of high quality. I remember that many foreign public places wrote in Chinese: Don't litter. Don't make any noise or anything. I think our citizens have had a bad influence on foreigners, so you have been targeted.

Another possibility is that the friend ruled out China. None of this is clear.

Maybe that friend was dumped by China's boyfriend? Laugh ~ joke)
