From Han Liuxiang's "Say Wu". If we don't intimidate those little evils, those big evils can't be punished.

Second, greed is the root of all evil; People with few desires are the foundation of all good things.

From "Cautious Words and Experience" by Wang Mingting Xiang. Greed is the root of many evil acts. Indifference is the cornerstone of many good deeds. Covetousness is the root of all evil. It is precisely because people are not satisfied with the material that they breed all kinds of evil psychology, gradually break through the moral barriers and embark on the evil road.
