As for jake, i think he refers to the angry baboons as the middleaged men whose last resort was go to China due to bad luck at getting jobs back home. They go to China with their masters in education that they most likely did as an online course.

In retrospect, it's not rocket science to teach 3 year old chinese kids english. I did just that, with flashcards, games and singing songs.
Jake could start at KG level, after a year or so move to middle school. You can't just get a piece of paper saying you're a teacher without stepping foot in a classroom.

I did a TEFL as Jake did, went to Beijing and taught KG for a year. I think anyone who has a years teaching experience in a Chinese kindergarten compared to one old guy who is doing a masters in teaching with no experience of kindergarten - The person WITH the experience would be hired first as a kindergarten won't pay 20,000元 per month for a new teacher with NO experience.

Hold on to your Z visa's Jake, that's proof of employment
