The original sentence of this sentence can be traced back to the ancient Chinese philosopher Zhuangzi, who was a famous philosopher and writer during the Warring States Period in China. He once said something similar: "Good people govern good and evil people govern evil. There is no good or evil in the world. There is nothing good or bad in the world. There is nothing wrong in the good; there is nothing inferior to the evil." The meaning of this sentence is that a kind person Even when a person does bad things, he is still a good person; when a bad person does good things, he is still a bad person. Zhuangzi's thought emphasizes the inner essence and personality integrity of human beings, not just superficial behaviors and performances.
