"Avoiding problems down the line", that can be a big problem! Some Chinese bosses in the field of education are not averse to using a scapegoat to get rid of an FT he(or she) dislikes, maybe due to skin color or something else. It's pretty much the case that employers in China consider themselves to be God. Though there are many opportunities for black teachers in China, how does that 'many' compare in quantity and in quality with the 'many more' opportunities for non-black teachers in China? I'd say there is no comparison in terms of quantity of jobs or quality of jobs. Far fewer Chinese employers will employ black teachers than will employ white teachers. What's more, the better and more prestigious jobs tend to go to white people. We should face the reality of being a black teacher in China. Not perfect, but a job's a job!
