The slogan of observing corridor discipline in schools

corridor

Don't run,

safety first

That's great.

Take the stairs in order and don't make any noise when you enter the classroom.

There is no frolicking in the classroom corridor, but the students are playing and watching.

order

Solid line, dotted line,

street crossing

, are all life.

Safety rope

Crossing the road: at first sight, second class, third crossing.

There are thousands of roads, and safety comes first.

Hope to adopt ~ ~
