The reason KJN Hwang Kee decided to change the name was because he wanted to take the style back to what it was originally - Soo Bahk. He called it Tang Soo Do to start with because that literally translated as 'Karate' which was known in Korea as a martial art - he was simply going for something that the general public could automatically relate to. The other options he considered was Hwa Soo Do (The Way of the Flower Hand). As for Soo Bahk Do being separate to Tang Soo Do, it is now, more so than ever. This is because those Do Jangs idetifying as Tang Soo Do are no longer under the guidance of Kwang Jang Nim H.C. Hwang and therefore don't have access to the guidance set up by his father, Kwan Jang Nim Hwang Kee. The Tang Soo Do associations are very strong, but they are out there thirving on their own since they broke away from KJN Hwang Kee. Forced Ryu Pa in action. About the style changing, it's NOT moving towards being more Chinese, but moving towards being more Korean. The new Hyungs (Yuk Ro, Chil Sun, Hwa Sun, Sip Sam Seh, etc) have been taken from the Moo yei Do Bo Tong Ji (historical Korean martial arts document). Yes we still study the older hyungs as well - such as the Pyong Ahns, Bassai and Ni Han Ji, and they still hold a strong standing within our curriculum.
