Draft a sign to the effect that no noise is allowed in the library reading room

Flowing water is ruthless and people are affectionate. I advise you to let Lou Qing calm down. The communication between the heart and the heart requires listening quietly. The water is not deep, if there is a dragon, it is spiritual. If the sound is not loud, if there is sound, it will be good. ; After class, be quiet. Your soft words are a sign of respect for everyone. In the future, let us cheer loudly. Today, let us read quietly.
