Yes, this one is going home. The buyers mailing address is in Chinese characters, but I learned a few months ago that Google translate can actually interpret those. Who knew? What I did last time was print out the address in English AND Chinese. The lady at the post office seemed to appreciate that. I will also use tracking this time, something I don't normally bother with.
Maybe the package was mailed from Tianjin (Tientsin) to or transited through Canton? All but one of the postmarks is 2Feb1954 Tianjin. The single Canton postmark seems to be dated 6 days later -- maybe a receiving/transit postmark?
