We don't use chinese charactors in real life. Well pretty a lot of korean words are composed with chinese charactors but It's just like..etymology. Although Koreans learn Chinese charactor since when they are elementary school student..But It is just for cultural studies. For me, I'm still confused even how to write one to ten in Chinese charactors.

I'm not sure where I got it from but I read that the older generation/elderly use hanja in some places
