1. This is the full tracking of your parcel:

China Post Register Air Mail Tracking System
Parcel No.RF324433463CN tracking result
2016-08-15 16:55:35.0 Electronic Data Received

2. May I suggest you read this:

Why does my tracking result show only one message “”electronic data received” ?

Hope this help.

But, why the status has not changed?

1. This is the full tracking of your parcel:
China Post Register Air Mail Tracking System

Parcel No.RF324433463CN tracking result
2016-08-15 16:55:35.0 Electronic Data Received
2016-08-27 09:22:12.0 China Post Group 泰州city parcel process center received
2016-08-27 20:00:00.0 China Post Group 泰州city parcel process center customs scan
2016-08-27 20:13:00.0 leaving China Post Group 泰州city parcel process center

2. So the last tracking/scanning of the parcel is this:
2016-08-27 20:13
Bulk mail processing center, Taizhou city, China Post group, left

3. Your parcel is leaving Taizhou city, China Post group for another location in China.

4. Just keep tracking your parcel and maybe tomorrow or after tomorrow you will see a new update for your parcel.

Hope this help.
