Hi Paul,
I just went to the Post Office and asked for it to be sent airmail to China with an address that QHY had provided to me.
My QHY12 originally came with an aluminium case so I sent the whole case back to them in an Aust Post provided cardboard box.
If QinXiaoXu has sent you the return info, just mark the parcel attention to his name.
I had to fill out this application form and send it attached to the box.

P.S. I replied to your email about opening up the QHY8L but it bounced back to me as undeliverable.
Cheers
Bill
