5 Things you didn't know about South Korea 1. In Canada, many people believe the number 13 is unlucky. But in South Korea, it's the number four that's considered to be bad luck. As for why it's thought to be unlucky? That's probably because the Korean word for "four" sounds a lot like the Korean word for "died." In a lot of elevators, they will use the letter "F" instead of the number four. 2. K-pop is a super popular music genre in South Korea. Its name is short for Korean Pop. The music is a combination of hip-hop, pop, rock and R&B. Thanks to the internet, K-pop is now a big hit with music fans all around the world — even with those who don't understand the lyrics! 3. South Korea is home to some of largest shopping malls in world. And customers can do some serious shopping, since many malls stay open until the wee hours of the morning — that can mean until 4 or 5 a.m.! 4. South Koreans use an alphabet called Hangul for writing. It was created in the 15th century and consists of 19 consonants and 21 vowels. Instead of being written in a row, like the letter you use in English to form words, Hangul letters are grouped into blocks of syllables. So, when you see a letter like this — 한 — it's actually a block of letters. 5. Kite flying is a popular pastime in South Korea. During the Lunar New Year, kite-fliers cut the strings on their kites so that they soar away. It’s believed that when the kites drift off in the wind, all bad luck floats away with them.
