International package from Nanjiing to jamaica

You can only send the package via Surface Air Lifted (SAL) Mail or Air Mail. The SAL costs around CNY 1,100 and the Air Mail costs around CNY 1,800. You can go to the China Post which located at Qiaobei Road, Wujiang Town of Pukou District.
Hope helpful!

Thank you for the reply. I have been to two China Post in the vicinity of Puzhen and Linchang and both says that my package is 122 cm instead of 100 cm so they can't accept. The option you have me is 4 hrs away, I'm closer to Linchang Subway Station (Longpan Road). So is there any other international China Post closer who does this? Cheers for your assistance thus far.

I found two China Post nearby Linchang Subway Station.
The China Post (Huaqi Branch) is located at Pusi Road, Taishan Street, Pukou District.
The other one called China Post Pancheng Branch is located at No.114, New Pancheng Street, Pukou District.
