Hi my package has been received by airline for the last 4 days is it gonna leave to come to Ireland soon as I need it for a birthday or has it already left China also the tracking on China post says “export customs departure” and then AfterShip says “airline received it” does this mean the same thing

Airline received means now your package is with the airline company. It is not sure how long it will wait to get a flight but normally it will not be very long, i guess you will see an update in the following days. If you are hurry to get something I think it is better to use dhl/ups/fedex because they have their own cargo planes. Right now you just need to wait . If you are too stressed, try to call the China post customer service and ask for the flight number planned for your package, you can then estimate the departure time

They have English service

Your package was sent from which city? The number is 0086-area code-11185, if you don't know the area code of the city, maybe you can simply call 0086-21-11185, this is the number of china post Shanghai
