Greetings from South Korea

The Greetings from postcard of the day comes from South Korea. I thought it would've been really difficult to get this one, but it turned out it wasn't that hard at all. Thank you so much, Hyemin!

About the facts on this card... I CAN'T STAND PSY, or at least I can't stand the one song I've heard and that everyone must know as it got played everywhere. It's got to the point where I'll try to leave the room if I hear that song, I just really, really can't stand it. Ugh. It would be nice to hear some *good* music from South Korea. :P

I also didn't know about 'Korean age' - does that mean that everyone in South Korea is a year older than they would be had they been born in any other country?
