How about JD Qiandeng No. 1 sorter?

The first thing I can answer you is that JD.com sorters are very tired and very hard-working. The most important thing is that most of the working hours are from night to early morning.

First of all, the sorting work usually starts after eight o'clock in the evening, because the parcels collected by the courier during the day will be handed over to the collection center at night, and then the real work begins. And JD.com also has a lot of express delivery, especially now that third-party merchants like JD.com have begun to receive express delivery, the order volume is even larger than before, so it is extremely normal to work until two or three in the morning.
