If you know EF first hand and if you know China so well as you claim, you will know that there are scores of schools/centers with little or nothing in a sense of course books, supplementary material or any other support to offer to FTs who have had to become more and more creative for the same or less money than before

A teacher should be able to create his own materials. And at a public job, no FT should need to rely on the school for that. EF's crappy materials, give teachers no freedom, I am sure turnoi will agree.

It is not about knowing China, but knowing what EF is, and we don't need to know about them first hand, because we don't work for them and never will@!
