Behind the Seams: Garment Manufacturing in Action

Hey, hey, it's too complex. I am asking you a simple image, just like show only four operators. One is doing his work, and the second one is also doing his work with low efficiency. And the third one is waiting for the one before him to complete the work. And the last one is sleeping, just like on their sheet, so they can do anything. He has to wait for the person to complete his work. But it must be in the sense of garment manufacturing.
