She develops skill of counting cash

Xu Yin starts work at 7 am, taking her place at her desk and turning toward a metal basin filled with small-denomination bank notes.

She picks up a spray bottle, squirts a little water over the cash, and then picks out a 1 yuan ($0.16) note, unfolds it, flattens it and lays it on the desk.

Within three minutes, she has counted 100 yuan. The burst of spray makes the notes easier to handle.
