My package hasn’t moved for 11 days. It still says “Arrival at office of exchange” and has done since February. My parcel was supposed arrive to me by tomorrow! I need that package for a gift. Tracking number: UP687080859CN
You may get the answer from the following articles:
There is no further update after March 2 because the package is sent by China post ordinary small packet plus. China Post doesn't provide tracking service for it after it leaves some stations of China. It usually takes about two months for it to reach and it's easy to be lost. You'd better contact the sender to give you a solution if you couldn't get it in time.
