Many Bank of China ATMs use the dollar symbol ($) to stand for RMB. So don't panic if your transaction receipt says you've withdrawn $5000. You have actually only withdrawn 5000RMB. One other tip when using Chinese ATMs: You might be told that your transaction has been "declined". So long as your home account has adequate funds, this advice is a misnomer. It actually means "the network is not currently responding, please try again later, or try another bank."
