I completely agree, it is IRRELEVANT. So why bring it up in the first place, troll?Because it's irrelevant to the discussion. He was searching for Chang Hon/ITF schools first and foremost, and concluded that only one was in existence in Seoul in 2011. The only part I disagree with (supposing they teach Sine Wave) is his label "traditional". The ITF was Sine Wave free in the 60s and most parts of the world in the 70s.
Here's a Chang Hon place in Seoul. Not that hard to find. There are four others just on the first page of Google if you search the Hangul. Some ITF, some not.
