About Moo Duk Kwan
Tang Soo Do means "Way of the China Hand". When the Grandmaster Hwang Kee, founded the Moo Duk Kwan in 1945, the common name for the kicking and striking arts of various kwans (schools) in Korea were called "Kong Soo Do" and "Tang Soo Do" until the merging of various kwans (schools) and renaming them as Taekwondo in almost mid 60s. However, Kwan Jang Nim Hwang Kee was determined to preserve and propagate the Moo Duk Kwan Tang Soo Do. Korean Martial Arts (Kicking and striking) such as Tang Soo Do, and even Taekwondo, are tracing their history from the ancient Korean Martial Art called "Subak" or "Soo Bahk" basing upon Korea's historical document called the Moo Yei Do Bo Tong Ji. To emphasize Tang Soo Do roots, the Grandmaster & Moo Duk Kwan founder, preferred to call his art as "Soo Bahk Do" which means "Way of the Striking Hand".
Soo Bahk Do or otherwise known as Tang Soo Do has spread rapidly in the United States. An actor who became well known as World Karate Champion in the early 70s is actually a Tang Soo Do stylist -- Chuck Norris, and he has been a help in the spread of Tang Soo Do in the United States. He later founded his own style based on Tang Soo Do. A well known actress Cynthia Rothrock is also 6th Dan Tang Soo Do who also trained in other styles.
