Library is not suitable for reading aloud, which belongs to a social norm, but when this social norm is internalized into its own internal behavioral needs, people usually have fierce internal contradictions. Because compared with the previous elementary school, junior high school and senior high school, the amount of memory that universities have to remember is really huge, so it is inevitable that many people have to recite it aloud. But on the other hand, other people will also ask the reading club to go to other places to endorse, instead of going to places like the library.
In this way, there will be fierce contradictions and conflicts between them, which can be said to be difficult to solve. Because the climate in China is very hot in summer, if you go outside, you will really recite in the scorching sun, while in winter, the cold wind is very strong outside, and basically everyone who endorses will not want to go outside, so if you can't go outside, you can only do it in the library.
The library is a relatively closed space. Anyone who has studied physics should know that as long as there are some sounds in a closed space, there may be a lot of sounds in people's eardrums, but it is unreasonable to simply ask people to abide by such social norms. So setting such an endorsement angle is a very good way to solve the contradiction between the two.
