There are no fewer than four slogans about environmental protection.

(1) The first step is compassion, and the spring is stronger.

(2) Planting a tree is like giving a gift to the earth.

(3) Establish the concept of environmental protection and create a green home.

(4) Let every drop of water be clear and transparent, and let every flower and tree flourish. Make the sky bluer, make the flowers brighter, and let the fresh air stay in the world forever.
