This kind of 11 digit number is china post ordinary parcel. It is a slow and cheap service for low value item. China Post will not scan and update its status after it left first post office. So you can not see new status and know where it is after it shows it's at Shenzhen process center. China post ordinary parcel might take 4 to 12 weeks to reach your country. If you couldn't get it within 3 months, it may be lost on the way. As your parcel was sent on August 29, 2017 and you still not get it, it must be lost.
You'd better try to open a dispute on AliExpress to get your money back or ask the seller to deliver again.
