Yup, Master Dong taught us that one, though we were taught to use what we called tigermouth stike hand shape like a C-clamp with the base of the index finger to strike the philtrum, apply upward pressure and close the thumb (one sinus area) and index/middle fingers (other side) closing the C-clamp for head control, additional pain and head control obtained placing other hand on back of head...worse if one used what He called the hammed and anvil technique, striking philtrum and palm to back of head same time.
I have the official (ok it is 15yrs old so I cant say its still taught) GPD non fatal thumb strike/control area under different part of jaw than my original post....
Should I start a new post for these or just hang here or forget about it???
do not try to spork the post, for that is impossible, only realize there is no post to spork
