One of my first dramas was "Lets Eat" which talks about Korean food in every episode. When I applied for the job at the Korean Language Centre, I was looking forward to showing off my Korean skills.
It was only after I got the job, I was told that actually, my Korean was very odd and many staff couldn't understand me. In fact sometimes I was using offensive words because my pronunciation was so poor. Many thanks to Lee Das Sol for being honest enough to tell me.
So take a tip from a member of the KLC Team. Don't rely on google translations or download lessons from the internet. That's not the real Korean Language, come to the KLC and learn true Hangul, the language of artists.
