Tang Soo Do is not the same as Soo Bahk Do^®.

The Tang Soo Do martial art system developed by Hwang Kee was an early precursor to his more advanced Soo Bahk Do® martial art system developed years later.

Moo Duk Kwan® martial art school Founder Hwang Kee taught an early iteration of his martial art system and philosophy under the name “Tang Soo Do.”  Later he modified the contents of his system and coined the name “Soo Bahk Do®” to identify his unique martial art system and philosophy being taught in all authorized Moo Duk Kwan® martial art schools worldwide.  His Soo Bahk Do® martial art system encompassed the content and attributes of his previous Tang Soo Do martial art system and was expanded and enhanced to include a significant amount of new content.

The Soo Bahk Do® martial art system is a living art that continues to evolve under the guidance of the Moo Duk Kwan President, H.C. Hwang, Kwan Jang Nim.

The Moo Duk Kwan® martial art school's high standards for philosophical understanding, technical excellence and rigorous quality controls stand behind every Moo Duk Kwan® rank certification.
