Want to know more about Korea and its culture? Who is more suitable than Psy himself. Check out Psy’s Wiki Korea where he teaches you how to name those Korean dishes with video and audio.

In my opinion, Korean Tourism Board is really more successful than Japan Tourism Board in promoting their country. They know how to make full use of opportunity to let everyone knows about Korea. Nice!
