Classified display, everyone praised.
Poetry is like this, I can't write it myself.
Small trash can, there is a lot of knowledge in it.
Blue trash can, garbage collection home.
Green trash can, kitchen garbage is poured in it.
The yellow trash can contains other rubbish.
Red trash can, harmful waste put it in.
Red, yellow, blue and green trash cans, don't make a mistake.
Men, women and children act together and use their brains to sort garbage.
Garbage sorting has many benefits, and the environment is good for three purposes.
I can do urban sanitation and create a civilized city.
