3. You parcel tried to depart China on the 6, 10,18, 24 Dec and each time there was nor room for the mail bag so the parcel came back and was reschedule.

4. The last departure attempt is on the 28 Dec, you will need to track your parcel to find out if more tracking will be added in China. If you don't see any tracking for the next 7 days, this means there is a good chance that your parcel is out of China.

5. Sorry for the bad news about your parcel, hopefully everything will go well from now on.

6. Just continue to track your parcel on the USPS site for any new movement.

Thanks.
