Please can you help, I sent a parcel home (to England) via snail mail from Xi'an on the 18th January, I am now home but my parcel is not. I have checked the online tracking and all it says is that it was in Beijing Int. Airport on the 21st January and there is no information after that. I can not find any contact e-mail for China Post at all. The tracking number is CP213767975CN, is my parcel lost? Please help!
