1. This is the full scan of your parcel:

Parcel No.RS047766466CN tracking result
2016-05-12 11:21:11.0 Dongguan city Post Office eCommerce dept. parcel center received
2016-05-12 11:30:02.0 Dongguan city Post Office eCommerce dept. parcel center customs scan

2016-05-13 12:37:42.0 Guangzhou Transit Station export security scan
2016-05-13 15:51:35.0 Guangzhou Transit Station export customs scan (domestic transit )

2. I suspect that your parcel has difficulty to pass the Customs scan in Guangzhou.

3. You should keep tracking it and maybe you could contact the seller and tell him about your parcel.

Hope this help.
