Personally, I hate such people. And I think this is what most people think. Because this will bring some influence to everyone in the library, they can't devote themselves to their own world and do their own things well, and they will be distracted by these noises, which is not conducive to the improvement of learning efficiency to some extent. Besides, there are rules in the library that don't talk loudly. If he still does this when he knows such common sense, it can only show that he is a person who does not keep public morality. We must teach such a person some lessons, let him know that it is wrong to do so, and let him restrain himself in the future.
