China Post tracking says it was delivered. I did not get it. Where was it delivered? China Post does not give a delivery address.

below Post Office Names are they all same?
1, China Post Agency
2, China post
3, South China Post Agency
4, China Post Office
I need to go to the correct China post for enquiry mailing to oversea.
Thank you
