Didn’t know there would be online friends interested in the TESOL industry in China here on micro.blog. Let me get this straight. In China, numerous EFL students as well as their parents attach excessive weight to accents. In the meanwhile, they show very little interest in communication skills, discourse chasteness, and eloquence, which should be the cruces of speaking (and even writing). So I don’t think a professional should suggest in the ad that his/her so-called native accent is the only ace he/she holds.
Additionally, many EFL students can’t distinguish between variations and wrong pronunciations. For example, some guys may think if someone’s about sounds like a boat, he/she is not speaking “pure English”.
Most Chinese people are not racially conscious or sensitive, and their preference for American and European (namely, British) teachers — who are not necessarily Caucasian — simply stems from a stereotype to break: a teacher (or any random guy in some certain context) from the UK and the US should speak “the purest English”.
