How it's used

Implies a deep, intellectual, and emotional connection that goes beyond just hanging out. It suggests someone who truly understands your inner thoughts and values, often used in more serious or sentimental contexts rather than casual social settings.

Examples

He is the best confidante I have had in my life.
Have you found your bosom friend yet?

Common phrases

close female friend of a man
close male friend of a woman

Common mistake

Do not confuse this with 普通朋友, which refers to casual acquaintances. Using 知己 for someone you just met or only see occasionally sounds overly dramatic or insincere.
