Four poems on garbage classification

Small trash can, there is a lot of knowledge in it.

Blue trash can, garbage collection house;

Green trash can, where kitchen garbage is poured;

Yellow trash can, where other garbage lives;

Red trash can, harmful waste put it in.

Blue, green, yellow and red trash cans, don't make a mistake,

Men, women and children act together, sort garbage and use their brains.

Garbage sorting has many benefits, and the environment is good for three purposes.

I can do urban sanitation and create a civilized city.
