Well...for me, I like making friends with people from different countries and cultures. It's really GREAT and FUN to learn something difference from other people.
Ya..I have to admit that sometimes problems or misunderstandings may happen due to the difference of cultures; however, everything can be overcome if people can be considerate and value the precious friendship in between. Can say..if you always bear in mind that people from different countries SHOULD have their own cultures and thinking, you can be more forgiving to accept the differences. If problems really come out, you can be more patient to look into it and get them solved with your friends. That's what I think!
So...actually don't be afraid~most people here in HK are nice and sure you can make many good friends here~~welcome to HK!
