Hi Laura,

Your package arrived Germany on Dec. 5 but not sure why it was returned back to China later. Now it's back in China now. The sender will receive it after several days. As you are in Germany, you can contact DHL Paket in your country to ask why it was returned back. Also, you should contact the sender to let him know it was returned and let him call China Post (11185) to ask what happened to the package.
