How it's used
Originating from triad slang, this term implies a connection to the underworld or a history of criminal activity. While it is widely understood, it carries a strong negative connotation and is often used in gossip or when discussing someone's background in a serious, cautionary tone. It is significantly more informal and evocative than the standard term 案底.
Examples
He has a criminal record, so many companies won't hire him.

Common phrases
to have a criminal record
to clear one's criminal record
Common mistake
Do not confuse this with the literal meaning of a black background or base, as the context of the sentence will almost always indicate whether it refers to a criminal history or a physical object.
