In fact, you can't stop those children who destroy flowers and plants in the park with any great words or poems. The reason is simple: children's thoughts and sentiments have not yet formed, and their ability to understand things has not yet reached the level of domestication with famous words and poems.

According to life experience, there are two suggestions: First, ask them which school and class they are in, and threaten them to find their class teacher if they destroy it again. Second, you should reason with them or write a sentence and stand there: "Please don't trample on flowers and plants, because they are as afraid of pain as you are." These are two methods that I can think of to teach students in accordance with their aptitude at present.
