I can't speak to the Australian situation, but the vast numbers of Chinese students in the UK are predominantly polite and respectful. That's no mean feat when you consider the subtle, complex and rather passive-aggressive nature of British etiquette.

I don't say this often, but this is straight up racism. You're painting an enormous group of people with a lazy and ignorant stereotype.

It isn't racism at all, literally no one claims ethnically Chinese people from anywhere other than mainland China behave like this.

Some people have to think rather than just regurgitating propaganda, this is a real problem.

Nationality is a race now? Great, when I check the race box from now on I'll just put "United States!"
