I know what you mean, that is right, we don't say "hello" to strangers, although many Chinese people believe it is common for us to do so.

Rather, what I was trying to say in that there is not a cheerful and friendly attitude among foreigners whom don't know each other. (Yes, I suppose in a village with only two foreigners in it, they would be thrilled to see each other.) But, I mean in your average Chinese city like Dalian, Shanghai, Guangzhou, and Xian.....etc.......

Most foreigners have a discontent feeling for each other(in China if they don't know each-other) like "oh great, another foreigner here to take advantage of this developing country", countless times I have walked by foreigners and seen others just have this "unhappy to see you feeling" or "what is this person doing in China". But, then again I sometimes do the same, like I saw a foreigner who was dressed all "skater-punk" with the spiky earrings and spiked hair, so of course, I gave him a look like "what is this guy doing in China" , couldn't he have left this spiky-punk silliness back home.

I think in a European country like Slovakia or Hungary, an American or Englishman would be thrilled to see each other, but in China it is like they disgust each other.
