EAP? Most FTs 'teaching' EFL in China wouldn't and needn't know the meaning of that acronym. So, I'll discount what you expect in that regard. What's surprising to me here in the PRC is that most FTs can't distinguish between EFL and ESL. That should tell you sth about the average FT here, and the low English levels of many Chinese students.

Now, re the Turnoi/Silverboy/ others warnings re lousy schools in China. I think they're justified despite their posts often having been blanket warnings related to the private education sector in China.

I'll provide an analogy:

Smoking can kill you, so don't smoke - I think you'll agree.
But I smoke, and have done so heavily for many years. Clearly I'm not dead, and if I died tomorrow as a result of it, I'd still have been happy to have done what I'd started all those years ago, namely smoking. But nevertheless I woudn't recommend others to smoke!

You can't and shouldn't generalise re Chinese 'schools'. It's a fact that FT turnover rates in the private sector, especially (lousy) training centres, are much higher than in the public sector. It's also a fact that private employers here will take on unqualified teachers, and are more likely to use and abuse foreign staff. There are always complaints re private schools in quantity online. Therefore, teaching in the private sector is much riskier than doing so in the public sector.

Teaching in the private sector here is like smoking, a risky proposition. You can't be against one without being against the other. Logic dictates that, eh! But of course there will always be those who survive happily in the private sector because they are born lackeys or workoholics or both while there will also be those who smoke and love doing so and have long lifespans.
