Back on topic, Xiangtan University Foreign Affairs Office cannot be trusted. If a foreign jobseeker is introduced to them through an agency, they'll try to get the foreigner to decline the job offer through the recruiter, and then accept it independently. In this way, the recruiter is cheated out of his commission. If that's how the Chinese FAO there deals with a Chinese recruiter, who knows what kind of trouble you will encounter there! Is the risk of going there to teach worth it? Not in my opinion!
