This may be true to some extent for low-profile teaching jobs where the FT applicant is not required to be a fully qualified teacher. My own experience is somewhat different: Unis and colleges, whether private or state-run, looking, that for foreign lecturers, professors or fully qualified teachers (with a teaching license in their own country), for example, will advertise on internet boards and other places abroad they know and where they can reasonably expect to find the kind of professionals they are looking for.

99.9% of FT's are low-profile teachers. The likes of you and Foxy Poster, fully qualified teachers, needn't concern us very much. Excuse me Turnoi but you shouldn't give the same advice to the majority of FT's that is only suitable for a minority- or indeed qualified teachers who merely wish to slum it in China...and that was meant in the best possible way....more like taking it easy.
