Singling out certain "schools" that are really bad is one thing and may help newbies to avoid them. In the end, it is only a temporary work-around. To make things really better, you have to ask the system question and analyze why such "schools" can exist at all in the first place. Then, change the system, introduce appropriate regulations, the bad "schools" will lose their market and will go down the river and never be heard of again. It is all about regulating a highly unregullted market; not only in China but everywhere in the world where such pretend "schools" exist. Such a regulation especially targets the kind of "schools" that you seem to defend - training centres. Their owners are parasites of society, and none of them is "good".

So hopefully people will take this seriously and put down the seriously crooked and abusive ones (not the ones you just had the usual disrespect from) but the worst of the worst actually screwing people.
