Seating is a ubiquitous behavior. I won't say anything if I meet someone who occupies a seat. If he is polite and occupies the seat, then I will abide by the principles and rules and let him occupy the seat. But if he takes a bad seat and takes it by some despicable means, I can't stand it. In fact, occupying a seat in a university is a very common behavior. Seating reflects the enthusiasm of learning. Because there are not enough seats, many students will take seats with books or other various items. A student who attaches importance to study and studies hard will not be too bad. He occupies a good position and attends classes, so it is possible and permissible to occupy a seat in the university. But pay attention to the way and morality. However, it is disgusting to occupy a seat without a lower limit. Some college students will use graffiti pens to write the words occupying seats directly on their seats to show their ownership. This is very uncivilized and immoral. Graffiti pens are difficult to clean by themselves. Although they occupy a seat, the cleaner's aunt will respect the screenwriter very much, which is much trouble. Another annoying way is to write a cursed note indicating that the seat has been occupied. If it is occupied by others, it will be cursed and die a natural death, which is very annoying. I think it's acceptable if someone takes a seat with human flesh. After all, someone else spent time and energy occupying a seat there, and I'm really embarrassed to dispute this with him.
