I've crossed paths with this guy and I can certify that he is a very dangerous recruiter indeed. He helped put me in a very bad way with a training type school in the middle of nowhere (Jiangyin City). He can and will change his emails and contact #s often. My feelings are that someone needs to grab a picture of the animal and post it online for others to see whom there are sealing their fate with if they deal with him in person.
I was actually at his place in Shanghai. If you meet him in person, he will do the switch and bait routine. My advice is to first screen his emails and contact #s online along with the school. I had screened the school and found bad reviews here about it. I should have stopped but I was intent on working in the Shanghai area and convinced myself that the school was good. On the other hand I didn't know how bad many of the Chinese schools can be as I was a complete newbie here, unlike Korea.
Please bring enough money with you (at least $1000 USD), especially if you're new because the chances are better than good that you will cross paths with a Frank Zhang type person during your journey and you will need the money to make a hasty escape. IMO, China is a *tough* place for an ESL teacher to cut their teeth on, much more so than, say, Korea, Japan, and Taiwan. Also watch out for the high number of degenerate foreign teachers, many of whom tend to be at least in their middle age and virtually unemployable outside of China due to numerous personal issues. Perhaps if you are the very patient type of person and are willing to invest at least one year here you will find something redeeming about working in China for well below $1500 USD/month. It's possible to apply yourself and make it here but there are better options for ESL instructors elsewhere to be sure.
