How Bad Guys Are Made tells the story of the protagonist Xie Wendong, whose "initiation story" has the structural framework of initiation stories. Xie Wendong's so-called "growing experience" is that he changed from a cowardly, filial, obedient and good student who was bullied by others with excellent grades to a gangster who killed people without blinking an eye. Of course, this novel is a reflection of reality: today's society is a law of the jungle society, and there is only one way to protect yourself, and that is to be a bad person.
