Yun Mu Kwan Yun Mu Kwan was founded by
Chun Sang Sup (전상섭) learned
Okinawan
Karate from
Gichin Funakoshi. Chun had a very close relationship with
Yoon Byung-In (윤병인) the founder of the
YMCA Kwon Bop Bu. Chun and Yoon would travel together to train with other martial artists, sometimes traveling to
Manchuria. They trained with each other so much that they became known as brothers. Chun went missing during the
Korean War; subsequently, this kwan voted to change its name to the
Jidokwan. After Chun disappeared in the Korean War, his original students voted for Master Yoon, who trained in
Chuan Fa in Manchuria, as the Jidokwan's first President.
Kwon Bop Bu/Chang Moo Kwan The
Kwon Bop Bu/Chang Moo Kwan was founded in 1947 by
Yoon Byung-In who had studied Chinese Chuan Fa under the guidance of a Mongolian instructor in Manchuria. Later, Yoon trained
Karate at the
Nihon University karate club in
Japan with
Kanken Tōyama. At one point, Japanese karate students pursued and started to beat up another Korean karate student who had skipped karate class to spend time with his sweetheart. After being persuaded by the other Korean student for help, Yoon used his Chuan Fa to skillfully deflect and evade the karate students’ strikes and kicks to the point that they gave up and ran back to tell their teacher what had happened. Teacher Tōyama invited Yoon to tell him about the skillful non-karate martial art he had used against his students. Yoon explained to Toyama about his Chuan Fa education in Manchuria. Toyama appreciated the Chuan Fa background since he (Toyama) had previously studied Chuan-fa in Taiwan for seven years. They decided to exchange knowledge; Yoon would teach Toyama
Chuan Fa, and Toyama would teach Yoon his
Shotokan Karate. Yoon later created his own art and called it
Kwon Bop Kong Soo Do. Kwon Bop is the Korean pronunciation of the Chinese word Chuan Fa. Early Chang Moo Kwan was mainly based on
Chinese Martial Arts (Chuan Fa). The early Chang Moo Kwan taught Palgi kwon (which was influenced by
Bajiquan). Yoon went missing during the
Korean War, but his teachings were carried on by his top student
Lee Nam Suk, who changed the name of the school to
Chang Moo Kwan. Even though Yoon had disappeared during the
Korean War, information about him was later recovered by original Chang Moo Kwan student, Kim Pyung-soo in 2005, when he found Yoon Byun-in's family. In addition to Lee Nam Suk's work with Chang Moo Kwan, other of Yoon's top students also carried on his teachings, namely; Park Chul-hee, and Hong Jong-Pyo (both Kang Duk Won). During the Korean unification of the
KTA in the 1960s, a small sub-Kwan broke away to form the Kong Soo Do Kang Yu Do style, founded by Grandmaster Jae Soo Kwon. Its location was Yongsan District Korea, outside of the U.S. military base; it then made its way to the United States. Outside of Korea, very few martial artists know or practice this style today. The name stands for 'the hard and soft way' or 'path of Korean empty hand.' ==See also==
