1. This is the full tracking of your parcel from the China Post EMS site:

2016-12-12 00:00:00.0 15:55:00 International Business Department of Fuzhou Branch Received and Accepted

2016-12-12 00: 00: 00.0 16:28:55 Fuzhou Branch International Business Department to leave the processing center, sent to Fuzhou

2016-12-13 00: 00: 00.0 15:54:30 Fuzhou leaves the processing center and sends it to USORDF = ISC CHICAGO IL (USPS)

2. Your parcel is On Route/In Transit to USA Chicago. Your parcel might be delayed.

3. When your parcel was sent it was not normal condition. Because:

Holiday Season
China Post has too many parcels to send overseas
Not enough room on the Aircraft for parcels
Smog in China delaying Aircraft or cancelling them
Rescheduling of mail bags
Chicago overwhelming of parcels incoming from Overseas.

4. May I suggest you contact seller and tell him you have not receive your parcel. He might be able to call China Post EMS to find out more information about your parcel.

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

Thanks.
