6. MA had been part of my life since my childhood; 4th grade elementary and continued and done research and developed via 자습, I've been on a journey of self-study and continuing education (CE) for more since 2005, which has led me to create my own system known as the "GhimSang System." It's not a distinct style but a personalized approach that suits me best. The GhimSang System encompasses a wide range of strikes from various distances, including kicks, punches, and close-quarters techniques, along with elements from Hapkido grappling.

In addition, I draw inspiration from various martial arts, including Chinese boxing, Sanda, Boxing, Muay Thai, Wing Chun, Xingy Quan, and the Jun-Fan System. Furthermore, my experience in Kumdo (Kendo) has made a significant and positive contribution to the development of this system.
