Nope. Not probably. IS. Because that's what the founders were taught.
Not according to YOON, Byung In. According to him, he studied Kung Fu and Shotokan. And he didn't claim to have taught ANY of the founders.
According to him, he did. Are you saying he lied about his training?
All of them that I listed.
Actually, he did.
His primary training was in Kung Fu, and his school was primarily based on this (similar to the Moo Duk Kwan).
LIES!!! ALL LIES!!!!
You're only saying all that support your agenda.
I don't know what your agenda might be - probably the same as mine - but it obviously needs supporting with lies.
Or you're mistaken.
