< I have to wonder why that, culturally, seems to be linked to Asians?
I can't speak for other Asian countries, but I know China. From what you wrote, your experience and the experience of Zhang Rui (the high school student) couldn't be more different. I've recently had the wonderful and depressing experience of teaching in rural Chinese high schools, and it was an eye-opening experience. The pressure and stress on those kids is simply astounding.
Unfortunately for Zhang Rui, there is probably no more important single event in his life than taking the University Entrance Examination (高考, or GaoKao). There are really only two life paths before him, depending on his score.
If Zhang Rui gets a decently high score, then he can attend a large university in a city like Beijing or Shanghai. He will receive an urban residence permit, and a small stipend that he can use to live as a student. He'll receive a degree without much difficulty, and he should be able to get a good job. He can become a professional, he can go into government, he can become a writer, he's got a lot of options.
If Zhang Rui gets a low score, then he has few or no options. He lives in a remarkably poor region, even by Chinese standards, and his father is probably a peasant farmer (or something close). He's probably also got a rural registration, so he'll never be legally allowed to leave his village. He can either follow in his father's impoverished footsteps or become an undocumented migrant worker, sweating in a factory or hand-mixing concrete on a construction site.
Those are the choices. Zhang Rui might be able to skip university and still lead a full and interesting life, but the odds are hugely against it. He'll have to fight the system until the day he dies.
This is the harsh reality that Zhang Rui is facing, and it helps to put everything into context. His father and teachers know all these things, and so it's likely they've boiled it down to a cold binary decision: either little Zhang gets into university and brings the family out of poverty, or he's another worthless peasant stuck in Anhui. The only thing that matters is the score on the GaoKao. It's horrible, but not uncommon.
I sincerely hope that Zhang Rui overcomes the system without losing his soul (or his life). He sounds creative, strong, and insightful. China could use more voices like his.
