Ed, I won't give you my sources, because they were given to me and not to you. They are published works that were sometimes comical translations of Chinese texts, but the information was accurate, and contains not only the location of the DM points, but the information to make it work.
The summary is written in my private notes as:
Chang San Feng, was born in the Lung Hu Shan of Hiangsi Province in 1247, during the period of the Emperor of Li Chung of the Southern Dynasty. He was asked to be commanding general of the country to conquer a powerful tribe that was causing trouble, but he declined. Instead, he passed the exam to become an officer in the royal court and to continue his work on his particular style of hitting points.
A dedicated Daoist, he regularly practiced his particular style of Tai Chi and hitting points, and studied the hitting points style of someone who had come before him named Feng Tao Yi. The study of his book developed into what we know today as the 36 vital points, but he continued to work on the hitting points based on the medical information developed by Dr. Pin Chuh (300 BC) and Dr. Hua Tao (born 190 AD).
The hitting points information was passed on to only his own students, for he feared the information falling into the wrong hands and jeopardizing his or the Emperorís life. Being an excellent military man, he realized the opportunity it presented to execute military operations using one skilled fighter rather than sending in hundreds of troops.
The process was to send in one emissary to negotiate with the other side and to send as his bodyguard, a fighter skilled in the hitting points. Once the main point was hit by the skilled fighter, the opponent would be badly injured resulting in death or being crippled. Once hit, there was no sign of apparent wound outside the body, but internally, he was seriously wounded or dying from having his internal organs damaged or smashing a major blood vessel, causing internal bleeding.
The art was so effective, that the legends of Dim Hsueh grew to the proportions that people feared that simply the waving of the hand of the practitioner could cause people to die. For that reason alone, there was a reluctance of teachers later on to pass the information on to anyone other than exceptional students, usually family members, who could be trusted not to misuse the skills.
I don't ask you to believe anything any more Ed... it always just becomes the next point of you arguing that it's not true... so go ahead and call this rubbish, but your google-fu skills don't work on my room full of books and private notes. You seem to think you're the only one that is capable of smelling out a faker or doing research, but having been around MA since 1962, I've seen them all... both the ones that actually had something, and the ones that were trying to be larger than life.
It's just a suggestion, but you might actually learn more by absorbing some information rather than trying to prove everybody that makes a statement is lying. That's really tiresome.
