You probably know how patriotic Americans are, right? Well: Chinese are the same! Chinese nationalism is a thing. Although I'm not sure whether you believe that.

In fact, nationalism is a thing in many Asian countries. In South Korea, there was recently a backlash against a K-drama for depicting that certain cultural elements may have originated from China. I don't know anything about the historical facts surrounding that case, but this is an example of how strong nationalism can be in east-Asian countries, including China.
