Can anyone help me with my package?

My friend just send me a package of 2.5kg from china to malaysia using EMS. I saw one of your answer indicating once the package fly out of china, i wont' be able to track my package using my code already, also, how do I know when the package is already fly out from china, also, once the package is fly out from china, roughly how many days it takes for me to receive my package? Thanks in advance.
