How it's used
Originally referring to the thirteen adopted sons of the warlord Li Keyong in historical fiction, this term has evolved into a slang label for undercover police or secret informants. It carries a slightly conspiratorial or noir tone, often used when implying someone is watching or gathering intelligence in a covert manner. It is rarely used in professional or formal contexts.
Examples
He works over there, I heard he is a secret agent.
Don't talk nonsense, be careful of the secret agents hearing you.

Common phrases
to act as a secret agent
Common mistake
Do not confuse this with the historical or literal meaning of thirteen sons, as modern usage is almost exclusively focused on the secret agent or informant connotation. Using it in a historical discussion might cause confusion if the listener assumes you are talking about police.
