I understand that there are very stringnet rules on transferring money out of China. Therefore I cannot help.
Eleswhere, one effective way of moving money around the world is to take out a pre paid debit card. These are provided like pre-pay mobile phone cards and you pay into them in your country of origin and use them in cash machines anywhere in the world thereafter. You could send one to a relative with no money loaded onto it, then once safely received, pay into the card and it can drawn anywhere else. However, this may be something that you wish to check out whether it is illegal for persons in China to do.
