How it's used
Refers specifically to the permanent record of a criminal conviction maintained by the police. It is frequently used as a warning to deter someone from committing a crime, emphasizing the long term impact on future employment and travel opportunities. The phrase is strictly reserved for legal contexts and carries a serious, cautionary tone.
Examples
It is really not worth it to get a criminal record from fighting.

Common mistake
Do not confuse this with simply being arrested or questioned by police. A person only gets a 案底 after being convicted of an offense in court, so using it to describe a minor police interaction is factually incorrect.
