The info on this page is ancient.It's a well known fact that most of the GLV "teachers" have no education whatsoever but they are good at "entertaining" students.Quality teachers do not stick around as they move on to greener pastures.The following types of "teachers" do not buzz:

1.people with no education
2.people who are on a fake degree/fake certificates (like the recruitment manager-zhuhai/epc/Hangzhou EPA who has traveled around the world but never been to school!)
3.non native speakers
4.native speakers with zero education
5.people who like to be spied upon
6.sex offenders

Now the good things:
1.pay on time
2.do your own shit in the classroom but keep the customers happy
3.no need to worry about your educational background as you will find many with similar background as yours
4.non stop gossiping
5.free shitty lunch and dinner if you really like to save money
6.annual bonus(read tip)

forget about "teachers",even the top management holds no education.all in all,avoid this "school". good place to make some quick bucks and sleep around with students but for long timers,a strict no no.
