When do you use 知道 vs 認識 when discussing when you know someone or some thing?
Normally we use 认识 when we say: I know this person.
And we use 知道 when we say: I know this place.
知道 vs 认识:

About &quot;people&quot;:

知道: Emphasis unilateral;
认识: Emphasis bilateral.





知道 can always be used about knowledge or information.
