First, the library is very noisy. Liang Wendao asked in his book Common Sense: "What made Hong Kong people lower their voices at the dinner table ten years later?" The reason is undoubtedly that Hong Kong people are getting richer and more civilized. Don't let your voice reveal your lack of education. Speak quietly, which affects others' study. This is the embodiment of basic quality.

Second, the behavior of campus couples is too intimate. Being too intimate in the library will have an impact on students coming and going. This is a place to study, not to show love. Others will look askance and distract students. The blow to single dog is too great.

Third, openly occupy the table and have no order. There are always some people in the library who occupy seats for others, resulting in people behind them having no place to study. Everyone should have a seat to keep order.
