Well, technically speaking, I believe you could drop a $5 bill into one of the forex ATM machines, and receive y32 or so in return. Alternatively, use your bank card at a conventional ATM to pull out y100 (just be sure to use a bank card that either reimburses you for fees like Schwab or one that is affiliated with a local bank -- e.g. BofA and ConstructionBank; otherwise you could end up paying the equivalent of y100 in fees).
But, if I were you, I'd withdraw y300 or so and grab a decent meal; it's not hard to spend y300 in Shanghai. Whatever RMB you are left with will almost certainly be worth more the next time you visit China.
