May be I shouldn't use the word 'stare',most of us just glimpse at the foreigners. But it doesn't mean we dislike or hate the foreigners. But I totally agree with you about the 'Hello" part. Nobody like that. Is any chinese guys do that to you? WOW,he or she must be crazy !

I think the staring is impolite. What is far worse, however, is when a person (usually with friends) walks up to me and screams "HELLO!" in my face, just to see my reaction and impress his friends. Also, hearing "hello!" in a high falsetto voice, just to make a joke. They are not being at all friendly. I find myself wondering why anybody would do that, especially seeing as the Chinese usually pride themselves on good manners. I guess with a small minority of Chinese, it just doesn't apply to foreigners.
