The grass is green, the air is fresh, the earth is green and people's hearts are moist.

Take care of every grass and tree and create a beautiful campus.

I gave the grass a love and the grass gave me a piece of green.

Sprinkle some green for the blue sky.

Give me a fertile soil and give you a new green.

The grass is green, the flowers are fragrant, the environment is beautiful and people are healthy.

Green is the color in our hearts. Protect it and nourish our hearts.

The grass is green and lush. Protect them and make the earth happy.
