This is part 6 of the Taekwondo Kwan history blog series. So far I have covered Chun Sang Sup, Yun Kwae Byung, Yun Byung In, Hwang Kee, Lee Won Kuk and now Ro Byung Jik. All of the blog posts in this series build directly from my upcoming secret book which does focus on a single Kwan, but none of the ones that we have covered so far. So which one is it? I still will not say, but I am sure many readers can now make a very educated guess as we have eliminated Yun Mu Kwan, Ji Do Kwan, YMCA Kwon Bop Bu (and Chang Mu Kwan/ Kang Duk Won), Mu Duk Kwan, Chung Do Kwan and today Song Mu Kwan. Like the other blog posts this one is rather short since I wanted to introduce the different major Kwan (schools), their founders and their martial roots, but they are not the focus of the book. Material on them are needed however to give historical context. I do hope you enjoy reading this series, and in the next part I will reveal the secret book project, the supersecret Kwan in great detail (since the book is really about one specific Kwan) and let the cat out of the bag. Hopefully the book will be fully formated and ready to be published by the time you read the next blog post in this series. In a way I will have given away much of the two first chapters of the book for free when you have read the next "episode", but I have always felt that knowledge is not something one should hoard or gatekeep and especially when it comes to the martial arts. Anyway, if you are curious to read on about Ro Byung Jik and his Song Mu Kwan here is the chance :-)
