Kyoshi is a Japanese title..but not the highest. Hanshi is the highest...or at lest that is what I was taught. I use Kyoshi..because the Korean title is Sambomnim which means "Master teacher". As a Christian since my Master is Jesus Christ..I can not allow anyone to call me that...just a personal thing. In class I use my Chinese title. Si-Jo, which is used for both males and female...it means founder of a system. Tae Su Jutsu is a combination of Wing Chun, Tae Kwon Do, Tang Soo Do, and American Freestyle. It is my system...and it is geared to allow the student to learn to defend themselves earlier, than in most traditional systems. I have been in the arts, since age 11...so to me it is a complete way of life. I hope I can contribute to the discussions in the great forum. I am looking forward to speaking with each of you. Take care, and God bless. Peace, Tae
