I have sent a packet from Germany to China by DHL on 9th Feb 2022.
DHL gave me a tracking number: LP044831611DE

The tracking by DHL stopped on 25th March 2022

According to DHL, the package has been handed over to the China Post. And I should track my package with the China Post tracking website.

Here is the DHL tracking website:
https://www.dhl.de/en/privatkunden/pakete-empfangen/verfolgen.html?lang=de&idc=LP044831611DE

Please put recipient zip code "461000" on the tracking page.
Then, then click "shipment tracking in foreign countries"
Then, I came to the tracking system for China post here: https://track-chinapost.com/track_4px.php?code=LP044831611DE

However, the tracking system for China post keeps saying that the tracking number "LP044831611DE" is unknown.

But the tracking number is correct according to DHL.
What can be the reason?

DHL told me that the package was sent in Feb 2022 and by now it must have arrived already. My recipient says he has not received it.

I appreciate any advice on this.

Many thanks in advance.

Thanks a lot for your info! This is super helpful and I finally know where my package is.
The receiver told me that he has contacted customs already. Will the package be shipped to the receiver soon?
