Keep the earth away from pollution and let green come into our homes.
Plastic packaging for one day, white pollution several times.
Rational use of resources to protect the ecological balance.
Garbage sorting, recycling.
In order to campus more beautiful, do not pick flowers.
Protect the ecological environment and achieve sustainable development.
Let the green hope sprout from the campus.
With the top one sky, one side of the water protection.
Love the clear water and blue sky and embrace perfect tomorrow.
The environment was clean and everyone was happy.
