Similar experience(s):<p>I went to the University of Washington, at which an extremely high percentage of the students were Chinese (I want to say between 30% and 40%).  Taiwan and the South China Sea are definite hotbutton issues.  Once during an international relations lecture of about 200 people, the professor made the mistake of mentioning Taiwan which caused one of the Chinese students to stand up and begin talking very loudly (shouting?) at the professor for what must have been a good three minutes, informing him that Taiwan is not the real China.  It was pretty painful to watch considering he was one of the most senior professors within that department, and very well versed on the subject.<p>Then I also had a Chinese roommate freshman year and there were always oddities like &quot;those people at Tiananmen had it coming.&quot;  Lots of little things that added up over time.
