NULL means the China Post website has a technical problem and the status can't be translated correctly, PEK refers to Beijing Capital International Airport, so your parcel was delivered to the airport to the destination country. Also check the status in your country post office website. I have a parcel delivered on april 22 and it's coming to my city now, just wait a little more...
