Cha Yun-do is similar in a lot of way to traditional arts like Tae Kwon Do, Tang Soo Do, Karate, etc. in that Cha Yun-do has patterns (kata/pumsae or poomse) and combinations. There are two main differences, the first is that Cha Yun-do is founded on Biblical principles grounded in the Word of God. The second is that Cha Yun-do’s combinations and patterns are the same movements and techniques used in standard sparring drills. Lastly, everything taught is for self-defense; one purpose; one direction; one system.
