Departure from outward office of exchange THEN opening. What does it mean?

I have a China Post Registered Air Mail and I just can't understand what's going on. I've tracked it in several websites and each of them gives me a different information. My country's postal service site says my parcel has only been posted, but china post site says the following:

item No. Year Status Location Destination Country Date
RA654687941CN 2013 Collection 43005800 BR 20130723 0812
RA654687941CN 2013 Opening 43032100 BR 20130723 1037
RA654687941CN 2013 Dispatching 43032100 BR 20130723 1128
RA654687941CN 2013 Departure from outward office of exchange 10010200 BR 20130725 1012
RA654687941CN 2013 Opening 10010200 BR 20130725 1600

They practically say my package has left China (departure from outward...) but in the same day it remained in China (opening)! Does anybody understand what this is supposed to mean? Has my package left China or not?

Thanks a lot!
