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.

A piece of paper civilization, every move shows civilization.

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

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

The garbage was thrown on the ground, and the shame was written into my heart.

More awareness, more cleanliness.

Step forward, civilization is very.
