I am posting here because I hope that some of the things I have to say may be useful for some FTs.
For the rest, I do not really care.

You need to write that in-depth guide, so that FT's can dispense with the services of all the recruiters you don't like. With respect Turnoi, you didn't do so hot a year ago, presumably finding your own two jobs in China, without recourse to a recruiter(must have been the case since you have been advising FT's not to use recruiters for years) which only lasted two days each,costing you 4000 yuan, as I recall. I should try a recruiter next time- it certainly won't be worse. Not a good advert for contacting schools yourself-am I right or am I right?
