Master "Iron" Kim's goal was to teach the Oom Yung /Chung Moo line to people of all nations, and to do that, he planned to build a strong foundation of martial arts in the United States from which to spread worldwide. With this goal, Master "Iron" Kim left the Orient and came to the United States in the early 1970's.
Upon arriving in the United States, Master "Iron" Kim felt he could best begin to teach martial arts by first learning basic English and American culture. In 1972, Master "Iron" Kim introduced the Kong Su martial art style in the United States. It was in 1972 that Master "Iron" Kim demonstrated the discipline and strength of (Kyong Gong Sul Bope) by successfully jumping from the top of a building eleven stories in height. Very few individuals have ever accomplished such a feat. Between 1973 and 1979, after educating himself about the American way of life, Master "Iron" Kim opened the first of four schools that he owned in the United States. Many times in areas where schools became established, the local paper would interview Master "Iron" Kim and write articles about him and the Oom Yung /Chung Moo style of martial arts.
In early 1975, Master "Iron" Kim briefly returned to Korea. It was at this time that Grandmaster Wang Po, the 7th generation Grand Master of Yin Yang Doe, passed to Master "Iron" Kim all the knowledge and traditions that had been passed to him. Soon thereafter, the title of 8th generation Master of the Oom Yung line was bestowed upon Master "Iron" Kim. Grandmaster Wang Po passed away in 1976 in Pusan at the age of 93.
In 1975, after the untimely death of martial arts actor Bruce Lee, Warner Brothers motion picture studios began their search for a replacement. After auditioning martial arts "experts" from around the world, Master "Iron" Kim was asked to screen test and was subsequently pronounced Warner Brothers selection. At that time, Master "Iron" Kim was forced to choose between a motion picture contract or to continue teaching his art. Master "Iron" Kim chose to continue sharing his knowledge, which has proven to benefit so many thousands of recipients of his training. It was also in 1975 that Master "Iron" Kim was the principal martial arts demonstrator for the promotional produced for the feature film "Billy Jack". In this exhibition, Master "Iron" Kim led approximately one hundred twenty-five martial arts masters and experts from around the world along with over one hundred actors and actresses. Again in 1975, Master "Iron" Kim was the principal demonstrator for the International Martial Arts Exhibition benefiting the "Asian Orphans Charity." Over thirty masters and experts assisted Master "Iron" Kim in this worthy cause. The proceeds from this charitable event provided aid to children of all nationalities.
In 1976, Master "Iron" Kim taught U. S. military martial arts instructors from all around the United States. These training sessions were conducted at Master Kim's training center near Ft. Jackson, South Carolina.
From 1977 through 1982, Master "Iron" Kim devoted his energies to training a select group of black belt students who had previously demonstrated both outstanding abilities coupled with the mental or "chung" discipline that Master Kim requires of all advanced students. Then beginning in 1983 and continuing through 1989, Master "Iron" Kim concentrated on training selected 3rd degree through 8th degree instructors and masters.
In 1989, Master "Iron" Kim chose the name Chung Moo Doe for the first time in the United States to represent the heritage of the royal line of martial arts for the first generation of practitioners.
The annual "Eight Martial Arts National Championship Tournament" began in 1990 and has been held under the name of Chong Su Nim (Honorable Founder) "Iron" Kim whose great skills are recognized internationally. This event is held for both students and instructors, with medals, trophies and certificates awarded at the competition's end. Between 1990 and 1995, Master "Iron" Kim presented honorary martial arts certificates to United States' Senators and Congressmen as well as numerous judges, government officials, police and military officers, television anchor persons, clergy and community leaders. These individuals have all recognized the vital role that Master "Iron" Kim's teachings have played in inspiring hundreds of thousands of people throughout the years.
Master "Iron" Kim trained the instructors who demonstrated the proper use of weapons and "empty hand" combat to members of the FBI during the 17th Annual International Asian Organized Crime Conference held in 1995.
In 1996, Chong Su Nim "Iron" Kim formally became Grandmaster "Iron" Kim of eight different martial arts disciplines and retired. Unlike the average retiree who turns their thoughts and life in a new direction, Grandmaster "Iron" Kim has intensely undertaken the study of bettering the physical and mental abilities of all age groups, with special emphasis on the aging.
Throughout history, few have earned the status of Grandmaster. Before he came to the U.S. in 1972, Grandmaster "Iron" Kim had achieved the highest skills possible within the eight different Martial Arts (Moo Doe). He is one of the very few people, to our knowledge and belief, who can visibly demonstrate the miraculous Moo Doe strength mentally and physically. Grandmaster "Iron" Kim is considered to be one of the most powerful Moo Doe (Martial Arts) practitioners in the world.
