As for spying, China is a country notorious for its citizens taking an unhealthy interest in what laowei are doing. Anyone touchy about this shouldn't come to China to teach. There will be appointed spies in your every class!

You couldn't make this up, yet your criticize the UK police for kicking in a front door and arresting someone for making a insulting or racist post on twitter, which can't be accessed in China anyway. I think I need beer now.
