06193342263 is china post ordinary parcel. This kind 11 digit parcel is a cheap service. http://track-chinapost.com/startairmail.php shows it was shipped on Jun 28. No other information will be updated.

When I track on the link you sent, it says : the server is busy, so I can not track anything.

By the way, what can I do now? Definitely, it is your service, right?

when server is busy, you need try many times. Actually I have already tracked for you. it was shipped on Jun 28. China Post will not scan such parcel after it left first post office, so there will be no more update on your parcel.

Right now you can do nothing but waiting.

One last question: How can I know that the parcel is delivered or not, or which post office has received it?

Thanks.

U wont know anything other than what is already available on china post website. Once shipped, its either u receive or u dont. The tracking will just remain frozen forever like that regardless of what happens to your parcel.
