Not afraid of not being smart, but afraid of being too smart. If a person is too smart, he will fall into blindness and become arrogant and ignorant. At this time, a person who looks smart is actually half a fool! This is just a little more courage than a fool, a little more hypocrisy than a fool, and a little more tricks than an idiot. This kind of "intelligence" is actually not better than fools, fools and idiots, but more pitiful, disgusting and pathetic. Their scheming is obvious, and they have become villains in everyone's mouth, but in fact, although they have fallen under the stigma of villains, they did not get any benefits in the end. They are still down and out.
