As a part of my effort to immerse myself in this drastically different country – I have signed up for Hangul (Korean). My goal is to be able to read the random signs written in what looks like gibberish by Jan.
Aside from being able to read basic phrases, the class is good for random facts such as the one I learned last week.
Koreans have a certain superstition for the number 4. Similar to our 13, it is considered a dark and deathly number. Unlike our unlucky superstition, however, they do not have any floors that are at level 4. It simply skips the level. 1,2,3,5,6!I assume the tradition translates to other areas too…4 kids, bad. 4 eggs, bad. Group of 4, bad. Nov 4th…bad.
Yet another random fact of about Korea. Good for cocktail parties or just something random to start off the conversation.
Vive ut Vivas 
I find it amazing that anyone/any culture can put so much stalk in a superstition. It is incredible that the Koreans find the number 4 such bad luck that it is also ingrained in their structural world.
I believe this behavior reinforces the superstition….fear is passed on.
