Welcome to the Korea Dangsudo Association!

The KDA is built on the historic effort to preserve the Korean martial art of Dangsudo (Tang Soo Do), which has roots in Korea, Okinawa, Japan and China. The preservation of this historic art is the utmost concern of the KDA and we are very excited to share this effort with you.

Due to the political and legal battles, as well as upheaval within the Moo Duk Kwan itself. Much of the martial art of Dangsudo has been changed. The Korea Dangsudo Association (KDA) has been created to preserve this historical martial art of Korea and to protect it for years to come.

To achieve this, Grandmaster Carlos Alayon went back to the roots and became students of the two highest ranked Dangsudo practitioners in the world. Grandmaster Kim Yong Duk, Dan #2 (RIP), Grandmaster Choi Hee Suk, Dan #3 (RIP); As well as the famous Grandmaster Chang Il Do, otherwise known as Bruce Li (RIP). It is from these gentlemen that the KDA flows forth into the world.

We hope website helps you in your Dangsudo Journey. DANGSU!


Grand Master Carlos Alayon was born in Arecibo, Puerto Rico on July 13, 1960 and started practicing Dangsudo Moo Duk Kwan at the age of 13 under the strict guidance of Grand Master Manuel Siverio. Many years of training under Grand Master Siverio ended when he moved to the U.S.A. to start his professional stuntman career. At that moment Grand Master Alayon contacted Grand Master Kim, Chun Sik to join his organization and started practicing under him from the middle of the 1980's until 2001. By the end of year 2001 Grand Master Alayon resigned from the International Tang Soo Do Federation. Afterwards Grand Master Alayon starting traveling to Korea and China to train with many Masters, Grand Masters and Senior Grand Masters like the Late Great Grand Master Kim Young Duk, Great Grand Master Choi Hee Suk, Grand Master Lee Sang Kyu, Grand Master Hong Jong Kuk (Chang Il Do), Grand Master Choung Koe Woong and Grand Master Kim Ivanhoe. In the year 2003 Grand Master Carlos Alayon was promoted to seventh degree black belt (Chil Dan) by Senior Grand Master Choi Hee Suk, Grand Master Lee Sang Kyu and Grand Master Kim Ivanhoe in Seoul Korea .

On November 1, 2013 Grand Master Carlos Alayon was promoted to eighth degree black belt (Pal Dan) by Senior Grand Master Choi Hee Suk, Grand Master Lee Sang Kyu, Grand Master Hong Jong Kuk and Grand Master Choung Koe Woong in the Korea Moo Duk Kwan H.Q. in Seoul, South Korea.

Grand Master Carlos Alayon won many tournaments and performed many Amazing demonstrations domestically and internationally. He has received many awards like "Instructor of the Year" in 1993 and 1994 by the Korean Martial Arts Organization, inducted in to the "Latin America Martial Arts Hall of Fame" in 1994 as Instructor of the Year and again in the "Legends of the Martial Arts Hall of Fame" in 2014 as The 2014 "Legendary Golden Pioneer" recognizing his 40+ Years of dedication, contribution and service to the Art of Dangsudo Moo Duk Kwan. He has received many letters of Merit, Commendation and Appreciation from many Grand Masters Like Grand Master Kim Song Ki and Grand Master Kim Chun Sik.

Grandmaster Carlos Alayon was honored to have the opportunity to practice with many Legendary Great Grand Masters like Hwang Kee, Kim Yong Duk, Choi Hee Suk, Kim Song Ki, Shin Jae Chul, Hong Jong Kuk, Kim Chun Sik, Nam Soo Yoo, Choung Koe Woong, Kim Ivanhoe and Hwang In Moo (Hyun Chul Hwang) to name some.

Hwang Kee (Hangul: 황기; Hwang Gi; November 9, 1914 – July 14, 2002) was one of the most important figures in the Korean martial art of Dangsudo.  He was the founder of the school of Dangsudo Moodukwan.

Hwang Kee was born on November 9, 1914 in Jang Dan, Kyong Ki province of Korea, while it was under Japanese occupation. His father was a scholar and teacher, thus Kee was one of the few young men in the province to complete high school in 1935. Following graduation, he went to work for the Manchurian Railroad, where he claimed to have learned the martial art of Tantui and Taijiquan in China with a Yang Kuk Jin. Hwang returned to Korea from China in 1937. Throughout the 1930s and 1940s, while working for the Cho Sun Rail Way Bureau, he began to study Okinawan Karate by reading books available at the local library.

In 1945, Hwang Kee formed his first school. Initially he named his first  Dangsudo school Ministry of Transportation Hwasudo Dojang (Dangsu). Hwasudo means "Flowering Hand Way" and was a reference to the Hwarang. In the early 1950s, he dropped the Hwasu and changed the name of his school to Dangsudo Moodukkwan because Dangsu (a direct Korean translation of Chinese and Okinawan/Japanese "Tote/Karate") was more familiar to Koreans from their exposure to Japanese martial arts. Much of the philosophy and many of the original forms (hyung) and techniques were his versions of the Okinawan Tote and Japanese Karate mixed with his Tantui and Taijiquan.

Hwang Kee's version of Karate is still a prominent influence on Korean martial artists around the world.

Dan Number 3 was the highest Dangsudo Moodukkwan practitioner in the World.

Under the suppression of Japanese rule for 36 years, Dangsudo was in crisis of its termination, but after the Liberation in 1945, Martial Arts practitioners sharing the same intention around the late Kwan Jang Nim, Hwang Kee tried to make ‘The Korean Traditional Martial Art’ grow in Korea, but many groups or schools of the Traditional Martial Art in the midst of the Taekwondo unification joined the sports trend, facing another crisis of being buried in history again. Although I am an old man, over 90 years old, I feel I am a tough Dangsudo person, and I am determined to devote my remaining years to the restoration of the Korean Traditional Martial Art of Dang Soo Do.

Dangsudo sets the spiritual training, not martial skills as a basic. Whatever the state-nation may be, it is impossible to become a nation of independence without invincible willpower and healthy body. Invincible, healthy willpower becomes the basis of morality. Healthy mentality is really the cornerstone serving to form a right and righteous society.

It’s necessary to establish a Traditional view through the spirit of Dangsudo. Now, the high ranking Dan members of Dangsudo who will share this will and intention will bind four million or more Dangsudo practitioners scattered over the whole world together by making this organization of the Korean Traditional Martial Art of Dangsudo.

It is our goal that our authentic, spiritual Martial Art of Dangsudo is established as the amazing Martial Art that it is. As Dangsudo practitioners, we will passed down these historical roots, and reach this goal.

At the risk of my life, I earnestly promise to inherit and develop our nation’s traditional Martial Art of Dangsudo, which is a Martial Art that realizes humanitarianism, and a nation’s precious legacy.

Dan Number 312.  A student of Jeong Suk Kim (Dan # 158), Grandmaster Kim began training in Dangsudo in 1951. In 1956 he began teaching and has been dedicated to the growth of the art ever since.

He was instructor of the Korean military army brigade at Osan, Korea in 1957 and later founded the Dangsudo School at the US Air Force base, Osan, Korea in March of 1958.

On January 31, 1960 he founded the Dangsudo Regional headquarters at Kyoung Ki province of Korea.

Over a thousand of his former students have gone on to become high ranking Masters and Grandmasters around the world. Among those are Grandmaster Mariano Estioko, the second American to ever receive a Black Belt in Dangsudo (Tang Soo Do) and founder of the Western Pacific Tang Soo Do Association, and Grandmaster Chun Sik (C.S.) Kim, founder of the International Tang Soo Do Federation. To see a family tree of Master Instructors that came from Song Ki Kim, CLICK HERE.

Martial Art Practitioner, Becoming a Movie Actor!

Chang, Il Do is a high ranking member 9th Dan in Dangsudo. After learning Dangsudo in Cheonan, Chungnam when he was 17 years old, he worked as a martial arts instructor at the US camp at Song Tan, Kyong Ki Do Province. In 1973 when he was discharged from the military, he set up the first martial arts school in the premises of the 8th US Army’s Headquarters, Western people considered him to be “ Lee, So Ryong of Korea.” "Bruce Lee of Korea" 

In the days when a public servant’s month salary was tens of thousands Korean Won, the number of the martial arts school students who paid 6,000 Korean Won a month was as many as 70~80 . Chang, Il Do’s life came to be switched as he went to film auditions. A movie director, who was totally infatuated with Mr. Chang’s thick caterpillar eyebrows and excellent martial arts skills, picked out him as a leading role in the movie. 

Even though his acting in the movie was the first in his life, his appearance fees in the movie was as much as 200,000 Korean Won. In 1976, the film titled “Iljimae”, in which he did a leading role, made a box office hit, attracting as many as 100,000 film audiences only in Seoul. Thanks to “Iljimae” , Mr. Chang was casted for a Korea-Hong Kong joint film. 

Its title was “Three Bandits.” Afterwards, he abandoned the instructorship of martial arts in London, England, and committed himself to martial arts films only. By the way, with the release of the film titles “A Better Tomorrow” in the middle of the ‘80s, all changed. 

Even in the period when almost all people were enthused about bloody movies with a volley of gunfire reminding people of a battlefield, Chang, Il Do was committed to Martial arts and Martial Arts Movies without regard to other genres. Chang, Il Do’s prediction hit the bull’s eyes. In 1991, with the film “Hwang Bi Hong” he imported making a great success, the era of Martial Arts & Martial Art Movies made a comeback. 

Building the foundation for his business after the success of the film ‘Hwang Bi Hong’, Chang, Il Do came forward for “Dangsudo Restoration” he harbored in his heart all the time. In 2003, beginning to lay a cornerstone of Dangsudo restoration by opening Dangsudo English Moo Duk Kwan in Goyang city, Chang, Il Do devoted himself to restoration of Dangsudo by selecting the late Founder Hwang, Kee’s students, President the council, Choi, Hee Suk and operator Kim, Yong Duk as an important post holder for Moo Duk Kwan; in addition, taking up the post of secretary general of the Moo Duk Kwan for unity of all Dangsudo practitioners, he did training and research of mysterious martial art skills. At present, as a Senior Master of the Korea Dangsudo Association, he goes on an overseas business trip to supervise the Dangsudo Seminar, Dangsudo Belt Screening, and Dangsudo demonstrations and competitions, etc. 6 times to 10 times every year. Chang, Il Do’s only aspirations are to prove that “the National Martial Art of Dangsudo is the authentic and very best Martial Art of the world, and to set up the Dangsudo as the ‘Martial Art for all Korean people’ with the spirit of Dangsudo becoming the spiritual basis of the Korean people.

We send our deepest condolences to the family of Chang Il-Do. R.I.P. Chang Il-Do. For Chang’s filmography, go to his page on the Hong Kong Movie Database.

First, let us stifle some confusion. Dangsudo and Tang Soo Do are exactly the same thing. The Korean and Chinese words are exactly the same. The forms, techniques, history, ranks, etc... are the same. So why do we at the KDA choose to use a "D" instead of a "T"?


The Korean government has gone through a lot of work to romanize it's alphabet, allowing better transliterations of Korean words for Westerners. A good example of this is shown in Google Translate. If I were to type in "" the pronunciation shows up below as "dang".  If I were to type in "" the pronunciation shows up below as "tang". As we all know, the correct way to write Dangsudo in Korean is "당수도", not "탕수도". And therefore, we use the romanization "Dangsudo".
