I am heading back to the USA after working in China. I am looking to take what is left in my bank account in China.

Change of plans,

What is the most cost efficient way to do this? Should I take my money out in China and carry it with me as I travel back home and covert it back in the USA or is it cheaper to try to find an ATM in the USA that has union pay and take out the money from an ATM in the US? If not one of these are there any other better options? Thanks.
