"Wang Neng Hao," a life of self-denial and discontent, without improving one's cognitive level, yet seeking psychological balance with Don Quixote-like "toxic words" instead of facing various dissatisfactions in life head on. The majority of people spend their entire lives in this state. You might say they are kind, but in fact, when they put on a security guard uniform, they have the illusion of being a law enforcement officer of the state. They are only kind because they are not qualified or able to do evil. Therefore, the fundamental difference between people is whether they have a learning mentality, constantly improving and correcting their own cognition. The novel itself is a little digressive and not very concise.
