You can use the tone of green plants to say slogans calling for protection and care. There is a sunny road, why should we look for a new one? Less footprints, more green. The trees used to be bare, but now we have to protect the environment and move. With your concern, the school will be more beautiful. Please don't get too close and let me catch my breath. The flowers in your hand float through the fragrance, and pay attention to the grass under your feet.
