Ask a friend who works in Suzhou Jinlong Haige Bus Factory what he really wants to ask. Other bus factories will do.

I did it in it some time ago, but it's not clear how much I can do, but you can calculate it yourself.

I used to paint, that is, paint (all cars have to be painted). There are two workshops for painting, North and South. I'm in the south workshop. Generally, we make 13 vehicles per shift (* * * there are two shifts: day shift and night shift). We have a day off every week. There seems to be no night shift in the North Workshop. Do the math yourself.
