Yanwen reports that a delivery attempt did not work out. The note "Without authorization" suggests the carrier could not hand the parcel over, for example because it could not get into the building or complex, or because the person receiving it could not be verified or authorized. The message also says the parcel will be returned to the Yanwen warehouse, so the parcel is being taken back to a depot and is not with you.
This is an exception, not a routine step. A failed attempt followed by a return to the warehouse usually means the delivery is held up and will take longer than normal. It does not necessarily mean the parcel is lost, but it will not arrive unless the cause is fixed or a new attempt is arranged.
The parcel goes back to the warehouse and is checked there. Depending on the reason for the failure, it may be sent out again for another attempt, held while the address or access details are clarified, or sent back toward the sender. The tracking history should show which of these applies.
