People who go, "I'm not Chinese, I'm Taiwanese/Hong Konger" are 100% brainwashed liberals. And honestly, Chinese people who overly stress their city and provincial backgrounds are also pretty sus in my experience. There's a difference between city/provincial rivalry, which Chinese people do all the time against each other, and Chinese people overly stressing their city/provincial origins at the expense of their national identity as Chinese people. Experiencing Cantonese chauvinism irl is a trip.
