It's fiction.
In real life,by my own observations,I think that the Asian professors are much more ambitious for their pupils than the western professors.
i have also noticed that having spent over a year living in japan the professors and just general educators in general public schools like the one my daughter attended were all pretty much doing everything they could to work with each kid so that they could be productive individuals in society as well as to push the kids to do better as human beings unlike in most western schools ie the us where teachers are over worked and under paid and honestly all of them get to a point where they just do not fucking care as long as the majority of their classes moves on to the next grade they do not care sadly
Wow, Chinese teachers are savage. If this were the USA, the teacher would've been like "you can do it, i believe in you" regardless of what orange hair girl said.
