Is the logistics sorter in Zhong Bai tired?

The sorter is responsible for the receiving, delivery, warehousing, sorting, re-inspection and secondary packaging of express goods received by the express warehouse; Responsible for daily express picking, acceptance, loading and delivery of express warehouse; Responsible for ordering, sorting and sorting goods and other related work.

It seems to be manual labor, but the mental work is also considerable, because the sorter has to memorize all the road section numbers in the service area and ensure that they are accurate.

So I'm still tired.
