Again, as the link I provided explains, youth unemployment counts 15 through 24 year olds. And those stats can't exclude students because school education in China is mandatory, so anybody under 18 is in school by definition.
It's perfectly normal to get a part time job for kids instead enjoying their youth under barbaric capitalist regimes. Obviously, Canadian teens are doing child labour instead of doing literally anything else. I grew up in USSR, and I didn't have to be exploited in my teens. Amazing how you see this as normal.
