1. Not backwards, since China has concrete achievements such as manned spaceflight, fastest supercomputer in the world and 1st nation to achieve long distance quantum teleportation, with a distance record only recently broken by European universities. Can't fake those like you can fake Cantonese "classmates". Again I'm saying Turkey is backwards as an objective fact. You don't have the WIPO patents, the scientific papers or the concrete engineering achievements to dispute this.
2. I don't care about what overseas Cantonese think and neither do most people. Who are responsible for most Chinese accomplishments in athletics, literature and science? Not Cantonese. Not saying they're dumb, this is just a fact. So why do we care what they say? The more they try to distinguish themselves and the more they trash talk us, the worse they look. In the US, no one likes a rat.
3. You are also cherrypicking, and unlike you, I don't have an inferiority complex. Why are you so scared of Uighur women marrying Han males and the fact that Uighur males in general aren't seen as attractive by Chinese standards? I'm not trolling, this is just a fact.
