Graffiti, by definition, is two fingers up at society - right? Well not in China, “One China forever.” That’s a bit like Banksy scrawling pro capitalist messages without the irony.

But graffiti is not the only anti/pro establishment activity you see. The BBC ran a report a few months back on China's hip hop culture. Kids on the streets of China rapping about family values, loving your parents and supporting the regime. Not quite in the spirit of rebellion you might agree? But whilst Chinas zero tolerance to social disruption might offend our democratic tendencies – you can’t help but think that the threat of a knock on the door and a long stay in Qincheng Prison does seem to encourage a more positive form of rebellion. Would Banksy agree, probably not – but then I did see his latest book being heavily publicised in a Hong Kong bookstore.
