• Pinyin (with tone marks): wéi fēi zuò dǎi
• Part of Speech: Chengyu (idiom), Verb Phrase
• HSK Level: N/A
• Concise Definition: To knowingly and persistently engage in evil, criminal, and wicked activities.
• In a Nutshell: This isn't just about “breaking the law.” `为非作歹` is a strong, formal, and condemnatory term for a continuous course of action that is both illegal and immoral. Think of the classic movie villain, a gang of thugs, or a corrupt tyrant—they don't just make one mistake, they actively and habitually choose to do bad things. The term carries a heavy sense of moral judgment and is used to describe people who are a genuine menace to society.

• 为 (wéi): To do, to act, to behave as.
• 非 (fēi): Wrong, evil, improper, non-conforming.
• 作 (zuò): To do, to make, to commit.
• 歹 (dǎi): Evil, wicked, vicious, vile.

The structure is a parallel construction: “为非” (wéi fēi) means “to do wrong,” and “作歹” (zuò dǎi) means “to commit evil.” Putting them together creates a powerful, emphatic idiom that covers the full spectrum of malicious behavior. It literally means “to do wrong and commit evil,” leaving no doubt about the wicked intentions and actions of the subject.

• In Chinese culture, which traditionally places a high value on social harmony, stability, and order (和谐, héxié), the act of `为非作歹` is seen as a direct attack on the well-being of the community. This idiom is deeply rooted in historical narratives, from tales of bandits and rebels to stories of corrupt officials exploiting the populace. It embodies the ultimate antagonist in classic literature and modern wuxia (武侠) stories, where heroes often dedicate their lives to fighting against those who `为非作歹`.
• Comparison to Western Concepts: An English speaker might say someone “breaks the law” or is a “criminal.” While `为非作歹` includes these ideas, it's morally heavier. “To break the law” can be neutral (e.g., a parking ticket). `为非作歹` is never neutral; it is a moral condemnation. It's closer in feeling to phrases like “to be on a crime spree,” “to wreak havoc,” or “to be a scourge on society,” as it emphasizes a pattern of intentional harm and a complete disregard for moral and legal boundaries.

• Formal and Official Contexts: This idiom is frequently used in formal settings. You will see it in news reports about the police cracking down on organized crime, in court documents describing a defendant's criminal history, and in official government statements condemning corruption or terrorism.
• Everyday Condemnation: While formal, it can be used in serious conversations to describe someone's terrible character. For example, people might use it to talk about a notorious local bully, a scam artist who preys on the elderly, or an unscrupulous businessperson.
• Connotation and Formality: The connotation is extremely negative. It is a very strong accusation. You would not use this term lightly or for minor transgressions. It is considered a formal and literary idiom (`成语`, chéngyǔ).

• Don't Use it For Minor Issues: The most common mistake for learners is using this powerful idiom for trivial matters. `为非作歹` is for serious, harmful, and often illegal activities.

  • Incorrect: 他开会迟到了，真是为非作歹！(Tā kāihuì chídào le, zhēn shì wéifēizuòdǎi!) - He was late to the meeting, he's really committing evil deeds!
