Today YIR wants to mention “Hangul”, a Korean writing system created by King Sejong the Great, in 1443. He introduced it to his people in 1447. It was noteworthy for the ease of learning it. Prior to that, there were complex systems, which made it hard for any but the most educated to write anything, or read it either.
Today Sejong the Great is thought of warmly in Korea, where Hangul is still spoken, 570 years later.
Rhinos recall him as a Good Guy. (The writing, in Hangul, says, “Hangul”, we believe…)
