What does the pick-up code of the shoulder pole ring mean?

The pick-up code of the shoulder pole ring is the pick-up certificate and the pick-up code needed when online shopping goods are received by express delivery. The rookie station can't see what the buyer bought on Taobao. It is just a pick-up point for express delivery, which is used to help Taobao buyers keep express mail temporarily. When shopping, Taobao buyers choose to send it to the rookie station because it is inconvenient for them to accept the express delivery to their homes.
