RC910871616CN.... situation??

Yes, I got the same information as you did.
Usually, after the parcel was sent to the airport, it will be sent out of China soon. Probably, your parcel was delivered to its destination country now. Please take it easy and wait patiently.

I thank you for the information
I checked the website of the seller, and the report says:

I do not understand NULL PEK?
thank you very much

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. I have a parcel delivered on april 22 and it's coming to my city now, just wait a little more...
