Hi daisy, thank you for your help. Are you able to provide me some contact details of yuanyang delivery agent of Chongqing north. As I see my package was not picked up as of 17 November 2016. I am concerned that they may return the package to me. I have informed my friend to pick up the package at her earliest convenience.

Sorry, they are hard to get connected through phone or email. You can let your friend in China call 11183 or 11185 (then 8 for English service) which are the customer service numbers of China Post to check if the package is still there. Also you can require them to deliver again.
