...Having had the dubious opportunity of working for thr METEN/METRO chain schools.. in Dongguan, and in Foshan, I will reply...

This company offers a slick facade, and charges a premium rate to its students...
In Guangdong, the teachers are "hand picked" by a few English teaching supervisors...Generally in Shenzhen...

When I worked in Forshan, I happened to be the only foreign teacher that had a university degree... Apparently, that was essential for me, as I am a minority!

Apparently, the Guangdong teachers, as a lot, are illegally working there...as all their credentials have been processed in Chengdu...

The administration for the most part, embody the wort traits of local "professionals".

They are dishonest and corrupt...racist, and ignorant

I was "fired" twice...but it didn't stick...and I ended up walking away...

This chain school has even pirated some of its text books from the very well known
New Interchange...

...Still... they attract foreign teachers because of their slick facade, and higher
(in general) than average wages

It's business as usual ....in China
