You might be surprised, as I was, to learn that there has been criticism of Chinese teachers by Chinese students on Ren Ren.

In comparison, teaching in China is a real pleasure, maybe I'm lucky in where I work or maybe it's my approach.

Your first point about ren ren is interesting indeed. Never knew of this!

As for the 2nd point, this shines through in your post. Teaching in China is indeed a pleasure compared with any kind of work in the UK,in fact.
