There are over 10,000 fake unqualified foreign teachers cheating Chinese school kids out of real education. And 389 unlicensed TEFL job recruiters are responsible for this fraud. They supply the fake teachers with phony diplomas and tefl certificates, and resumes that are almost pure fiction. This is why the China authroities are now checking the visas and diplomas of every foreign teacher in Beijing and Shanghai. So far over 4,000 have been arrested and deported in 2017.
