Oh god, triple post of doom!
I have a question for anyone who's got anything on Chinese history, particularly social history though.
In general, have tattoos always been seen as a negative thing in dynastic China? I know that they used to have tattoo soldiers so that they couldn't desert the army and not be caught, and that tattooing was a punishment for criminals.
I get the distinct feeling that the answer is yes, yes and yes, since there were non-Han Chinese groups in the South that utilized elaborate facial tattoos as part of their religion and they were considered uncivilized barbarians, etc, etc.
I really want to give the police in wizarding China a fancy tattoo that marks them, I'm just not sure that it makes sense culturally or historically.
