Hmmm...well, I taught EFL for them some years ago. It was an authentic school then. They provided a low-cost/quality apt. in a nice Complex, with swimming pool/Jacuzzi, frequented by amiable Chinese Retirees.
"Hainan Premier School of Chinese & Foreign Language" (website: haikouschool.com/teach.htm; current address: "A4 Huaren villa, Haida road, Haikou city") has FAKE job "Vacancies" and "Openings". They are NOT teaching English!
