Null, Pvg since Dec. 23, 2013. What it means?

Following is the last known status of this mail.

The English information on the official website of China Post is translated from Chinese tracking status, but not all information can be successfully translated. So “NULL” is a technical problem of the website, not your parcel. "PVG" refers to Shanghai Pudong Airport.
