This person is long time con artist, who preys on the ignorant and desperate. I am hoping he would be out of business and shut down by now.
It is a sad state of affairs that many people may leave China with a horrible opinion because of this person. It is even sadder that he has negatively effected the relationship of many schools with not only foreign teachers, but with students as well.
I am making it one of my personal obligations to help shut these people down.
