Hi callawong,

It's retained at the customs of Guangzhou now. If it's stuck for over a week, it should be waiting for the receiver in China to declare to the customs now. You'd better contact the receiver in China to ask if he has received the notice from the customs. If no, let him call China customs service number 12360 to check.
