Hi Alex, I always book my hotels on a website (chinahotels.org) never had a problem with them, Quick response and a printed out receipt booking with the address in English and also Chinese "for the taxi driver" , As for changing money, I always change around $500 before I leave home and the hotel you stay in usually changes foreign currency with a better exchange rate than home, As for them inspecting them for writing and tears, I have never noticed them looking too closely at mine, They seem to lok more at their own money closely , As Willie said, There is a lot of forged note's here , As for the visa, Every country may have different requirements, What David said about the Australian visa was spot on, I'm on my third one now, Multiple entry for twelve months, John.
