A long, long time ago a man was sitting in his room (those little traditional Korean ones ^-^) thinking to create a new language for the newly independent country.
He wanted something simple in opposition to the complexity of Hanja (Chinese characters) and the three different alphabets of Japan.
He thought and thought but couldn't come up with anything; hoping to find some consolation from the
night sky, he motioned to open the window, but he heard that there was a lot of rain falling outside. He looked at the window.
In this window he saw some simple, yet powerful shapes to unify the broken Korea and get rid of illiteracy. And looking at this window, King Se-Jong invented Korean. ^-^.
