Certainly, there are plenty of Africans who have terrible English and should not be working as teachers even in the field of ESL, but there are also real western teachers who I have met that are of African heritage who can teach English just fine. I do think Yuncheng is not the type of city that would attract the best types of teachers, even pretend ones in the ESL field. On the other hand, the types of expats who work at these places both native and non-native no matter the skin color are not the kinds of folks I would ever keep in touch with if I ever have worked with them previously. Assholes and pieces of shyte come in all colors, genders, and backgrounds. A hative speaking idiot of English is still an idiot at the end of the day. Glad to hear you left the place, hope you find something better.
