As with everything in China, if you go to the same place two days running you'll get two different answers. Also as with nearly all Chinese rules, they change and are different depending on what province your in.
I think technically your extremely limited in what you can transfer and you must log it your Foreign experts certificate, blah blah blah. In reality their are a million different ways, it's just finding the best that works for you and if you don't get the answer you want walk down the street or try again the next day with a different staff member. Also ask around the company your working in when you get there. The other foreigners will have some scams going for getting their money home.
From memory Bank of China charge about 200CNY+some really small percentage 0.01%?.
Trust me when you get here getting yourself home will be a bigger concern then getting your money home.....
