Do not shout slogans in public.

Please don't make any noise in public.

Your whispering is a respect for everyone!

The water is not deep, and the dragon is the spirit; The sound is not high, as long as there is sound!

More than the sound tells them is silent, be careful not to lose your voice!

Quiet creates the beauty of harmony!
