This was ordered from AliExpress using ePacket on November 26th, and from the tracking it appears it was handed over to Shenzhen EMS on December 8th, 2018. Since then, it appears the originating post office was preparing to send it along its way, but absolutely no change in status occurs afterward. It is as if the parcel vanished!

Is this parcel hopelessly lost in the China postal system? Would I know if it has been detained by China export customs perhaps, would there be some sort of status indication?

If none of that, how likely is it that it was stolen (it was not a very high value item ($70USD))?

Thanks in advance for any assistance.
