How about the transit work of Hangzhou SF?

Hangzhou SF is very tired during transportation. Stand at work until you get off work. Sometimes it hurts to stand, but you have to keep working. Finishing is more tiring. You must keep walking and scanning the goods. At the end of the day, you have to walk at least tens of thousands of steps and bend over to work. Sorting is more tiring than packing. Packing is standing in one place. Classification is mainly because your feet can't stand it.
