There is a poisonous tree by the road.

The first kind of people saw it from a distance and took a detour. They don't want to get close at all, for fear of being poisoned by carelessness.

The second person came to the tree, saw it, immediately thought of its toxin, and was anxious to cut it down so as not to hurt people.

The third person has a different mentality and is willing to think with compassion: this tree is alive, too, so don't destroy it easily. So they put a fence around the tree, marking it toxic, so as not to hurt passers-by.

As for the fourth kind of people, when they see this tree, they will say, "Oh! A poisonous tree, great, this is exactly what I want! " They began to study the toxicity of trees and mixed them with other medicinal materials to make new drugs that can save lives.
