No littering in the trash can.

Garbage into the box, civilized and healthy.

Put the garbage in the box, it's easy.

Waste is thrown into my mouth, and my "big belly" can hold everything.

You are a little, I am a little, and he adds up. Environmental protection depends on everyone.

Every piece of paper is civilization, and every move shows civilization.

You throw away not only rubbish, but also public morality.

Pay attention to hygiene, love cleanliness, and put garbage into the basket.

Garbage is thrown on the ground, and shame is written into your heart.

More awareness, more cleanliness.

Step forward, civilization is very.
