Which is better, a stamping worker or a polishing worker in a hardware factory?

1. Stamping workers adopt mechanized production, without heavy physical labor, and their work is easy. Polishing workers are tired and need manual operation.

2. Stampers don't need to stand for a long time, but they can sit and work, and polishers need to stand for a long time, so stamping workers in hardware factories are easy to do.
