Campus warning:

1, green leaf safflower, how can you trample on it?

Pay attention to the grass under the ground when you step on it, and don't break your fingers.

Don't let the white veil cover my green smile-the message from the lawn.

When I strut, I groan at your feet-the grass is calling for help.

Caring for the environment is like caring for your own eyes.

Environmental warning:

1, don't let the last drop of water be our last tear.

2. Without green, there is no life.

Don't let the white plastic bag cover our white clouds.

4, the grass has life, please be merciful at your feet.

It's a pity that the grass is covered with grass.

6. Your actions represent the future of flowers.
