It sucks this is the world we're living in. When I think about it, I have never seen a black teacher in these Chinese online schools, which is just plain stupid. The Chinese can be very closed-minded and unwelcoming of anything new. I have heard that many condemn their mixing with any other race, for example I know a couple where a Chinese woman married a white American man and they had a mixed race daugther. They always get the looks in public and her parents object to their marriage. So you see, the Chinese still have a long way to go, but don't let it discourage you, maybe you can try this online school which is based in Iran. https://oteacher.org/en/become-a-teacher/
Good luck!
