Don't put up slogans.

Classroom is a place for students to study, and neatness is an important condition to ensure students' physical and mental health. This paper will discuss the importance and detailed requirements of classroom hygiene from indoor and outdoor environment, podium, tables and chairs, doors and windows, slogan code and so on.

1 The indoor and outdoor environment is clean and tidy.

The indoor and outdoor floors of the classroom are as clean as new, the wall railings refuse to graffiti, and stains, water stains and cobweb dust are all gone. The corridor is as clean as a mirror, the walls have no footprints and dirt, the doors and windows are as clean as new, graffiti is refused, and broken glass has nowhere to hide.

2 podium, tables and chairs are clean and tidy.

The podium is clean and tidy, the articles are placed in order, and there is nowhere to hide the sundries. Tables and chairs are arranged in an orderly way, and the items in the desks belong to their places. Neat and orderly is our pursuit.

3 slogan code is clear

Indoor slogans, codes and timetables are clear and tidy, unified and standardized, showing the class style.

Hygiene in a clean area is equally important.

The trash can in the clean area is clean and sludge-free, and graffiti is refused. Everyone praised its neatness and beauty. The ground is flat and clean, free from weeds and garbage, bricks and stones, and there is full of green in the flower bed, free from sundry interference, and flowers and trees are thriving.
