My turn, I have just sent all my stuff via CRE (China Rail Express) and it was surprisingly pain-free!
457Y (including 100Y insurance, that's extra) for 80kg (ooopssss......). Oh, and they told me it was no extra cost to have everything delivered to my door down south afterall.
Lugged in all my stuff with a student (unsealed), they threw everything throught the XRay machine, got the okay, filled in a form (only 1!!!!!!), guys expertly sealed everything up (was happy how well done it was), paid the moolah, put labels and extra bits on each piece and away it went. Maybe took 1/2 hour.
And apparently will only take 3-4 days from Baoji to Jiangxi!
