Every English department in every school will most likely have an English speaking member of staff. You can easily find their contact details, especially in the case of public universities. There is never a need to ever use a recruiter for finding these kinds of jobs.

Just go on Wikipedia, any FT can find a list of every university in China. The Wikipedia page of many of those universities will have links to the university's official website on the page. If not, it will still be easy to find.

Many will have an English version of the page. If not, google translate maybe won't do a perfect job; but will probably do a good enough job to enable you to find all those contact details. If you can read Chinese or have a friend that can, that would be even better. But it is not essential.

Universities probably only use recruiters because they are either: 1.) Unbelievably lazy 2.) Know that many FTs are too stupid to do their basic research.
