A slogan suitable for posting in the classroom about protecting the classroom environment.

I used it in our classroom before. I hope it can help you:

If you don't sweep a room, why sweep the world? Pay attention to hygiene. Everyone has the responsibility to be a good student and keep everyone clean. There are no footprints on the wall and no sputum on the ground. * * * Build a beautiful environment and create a civilized classroom. No littering, no littering, no spitting. The hygiene of the classroom is related to the health of students. Be a noble person and don't litter casually. Pay attention to hygiene and love life. The classroom is my home,

Love depends on everyone.
