2. It could mean 2 things. One is your parcel is trying to get on board an Aircraft by there was no room and is trying again on the 02 Oct.

3. The other one is a closer security check of Parcel is in place at the Guangzhou Airport and the mail bag that your parcel inside got stop and the mail bag was recheck for security.

4. To make sure that your parcel departed China you need at least 15 days without any tracking. Then there would be good chances that the parcel made out of China.
