The slogan to prevent noise is simple.

1, let's put out the noise together, and good news will come from all over the world. 2. When the bell rings, quickly enter the classroom; Walk like a cat and walk quietly. Let's create the same blue sky, eliminate noise, learn to listen and enjoy peace. 4, the water is not deep, there are dragons; The sound is not high, as long as there is sound. Your whisper is a respect for everyone. 6, whispering, benefiting others and benefiting themselves.
