Which is better, a laundry factory or a slaughterhouse?

Laundry factory It's good. Slaughterhouse is bloody, and a lot of sewage and waste gas will be produced in the process of slaughter, which is seriously polluted, and the staff needs to have a strong psychological quality. Laundry factory has a good working environment, no need to wear dust-free clothes, and the room is equipped with air conditioning, which is easy to be accepted at work. So the laundry factory is good.
