Hey Ms Dyell, if this will give you any comfort, I am also in the same boat, I posted a package for my girlfriend in Austria and 2 weeks and counting still not arrived. I did it by EMS which is usually reliable from my experience, but I guess the Christmas jam and traffic will slow things down a bit. My best bet will to call a hotline(for EMS - 11185) but you will need to speak chinese(i suppose), they can help out a bit but for the other couriers, google their hotline and let someone you know who speaks chinese help you out. Good luck. I am also fretting whether the package wil reach just in time for Christmas.
Just may be Santa is jamming the way with his big frame and goodies. Merry Christmas and may you receive the best gift of all : Your package.
