No, he is not trustworthy. His real name is Frank Zhang. He is a well known crook in ESL, and there is a mountain of complaints about him on the net and by word of mouth is this business. Another name he uses is "Alin Bauer".

Just keep the hell away from this person, or you will be sorry!

I have just received an unsolicited e-mail introducing a teaching vacancy at a Chinese university from a person going by the name of Sang Xing. Besides trawling the net, what does he do? Is he a Chinese recruiter? Is he trustworthy?
