It has been 11 days and I saw that this package is returned twice from Xiamen International exchange station. What does it mean? How long will I need to wait for the parcel to arrive in Sweden?

Hello,
Tracking package LL797248463CN (it contains a bicycle part) on 17track shows repeated "Beijing, Beijing Exchange Station Return" (4 times) and "Beijing, Beijing Speed International return, note: security return". What could be going on here?
