새옹지마 [塞翁之馬 Sae-Ong-Ji-Ma: The horse owned by the man, 새옹] This is the four character idiom(사자성어) which was originated from Chinese words. As I said, Korean language system such as the pronunciation and characters is completely different to Chinese language but Korean word's sources come from Chinese...So Japanese and Korean words have Chinese characters. Korean people say that the life is 새옹지마. ..
