Are the polishers in the hardware factory tired?

Working in a hardware factory is not only tiring, but also dirty and noisy, and the salary may be high. Polishing in the hardware factory is very tiring. At the end of the day, the hand holding the grinder will be broken, and you can't carry chopsticks without a little strength. There are many middle-aged men working in a hardware factory, but few young people and women. Everyone who works in a factory likes to go to the electronics factory to relax and have a better environment.
