When describing others, we can use the word 人家 (rénjia) or 别人 (biéren). But 人家 also has other grammatical uses, which we will explore in this article.
人家 and 别人 both refer to others besides the speaker and the listener. However, 人家 is more colloquial.

These sentences mean the same thing:

人家 can also refer to someone previously referred to (in the context of the conversation or body of text) or it can refer to a certain someone that both the speaker and listener know.
