They are into drugs, alchol, and the teacher in question is allowed to stay because he is Shuai's little dog. Being drunk in class in front of students, hiiting students. He writes reports on all the teachers and gives it to Shuai. Shuai charges the teachers electricity at a premium, gives no receipt and no official bill from chinese state grid - he just pockets it, so work it out 25x1000 each semester, then pocketing the travel and holiday money, he and this canadian teacher are making some serious money... and the government do little about it. He has free reign to do as he pleases. He has now a new ploy, employing indian teachers to teach english for 2500 yaun a month, and he pockets the rest, as the contract he offers the teachers differs from the one he offers the University, and the contracts have no power, they keep changing just like the wind, and this guy will make military, political and governmental threats to get his way and hold on to power. This is only the tip of the iceberg of what is going on.
Advice? yes, stay away, save yourselves the grief, pain and your Embassy a great deal of time, pain and worry, dont go there, keep away from this school. It is really very, very dangerous and they are corrupt from top to bottom, you can even disappear as Shuai threatens, and these threats are very real. STAY AWAY. KEEP CLEAR. DONT GO THERE. BE WARNED.
