I have been to nantong myself and I have to say there is a plethora of training centers that are new there. The city keeps on adding more and more every year. Eventually something like this was bound to happen. I personally have heard from a contact who works in the city talk about the inherent cheapness of people who live there locally. I have also heard this from Chinese who are not native to Nantong say the same thing. Let's hope more bad publicity from these pretend schools from this city get exposed!
