I am trying to send something by fedex to Chengdu, Sichuan 610000. Fedex will not let me complete the label stating that the zipcode is invalid. I have verified the zipcode and it is correct. Can you help or explain what I need to do?

WRONG = 38341, correct 70443 - USA

Hello
I did send two packages from China to Sweden. I did send 4 packages in total and 2 have been received. The 2 that has not been delivered are:
CP405187970CN and CP405188649CN.
For some reason has the digital adress not been written correct and I have therefore not received any notice about the packages.
Today did the Swedish postoffice inform me that the packages are sent back to China.
Please resend the packages to me with the correct digital adress.
Hope you will be able to help me
