Just here to confirm (i worked in Nanning recently) but yes he's right that Nanning is now horrible for cheaters, rip-off artists, scamming and pretty much just outright cheating foreign teachers (or any employees of any kind).

This isn't small rumours etc.. I mean its just amazing and not only was I totally robbed, cheated, scammed out of hours of work and time BUT every foreigner I talked to had horror stories, was being scammed, just recently scammed.

So can confirm: NanNing now just awful for massive employee abuse, theft and cheating. Its the worst I've ever seen in China and by quite a large margin now.

*tho many of these companies are from other cities I should mention*
