Have you ever worked at the bottom of a factory? Talk about feelings

After graduating from high school, I worked as a general worker in a lamp factory for 1.5 months. I have welded light bulbs on the most basic assembly line. It's the first time I go to work, and I feel quite novel and tired at work. No one at the bottom will take care of you, and it is easy to become numb. So I suggest that it is best not to go to work in a factory, even if it is from the bottom of a regular company. Because what you have learned is totally different.
