The magic that Christmas brings to people is the happy feeling. Merry Christmas everyone =) Christmas is 성탄절 (seogntanjeol) in Korean. Koreans definitely know Merry Christmas which is written as 메리 크리스마스 (meri keuriseumaseu), they actually greet the same way.
Another way to say this greeting is 성탄절 잘 보내요 (seongtanjeol jal bonaeyo). Literally means have a good Christmas but it also means have a happy Christmas.
It’s probably snowing in Korea this time. Hope everyone is feeling happy today enjoy the holidays!
