The Bubishi also contains a number of diagrams and information on the use of pressure points.
The pressure points in the Bubishi are thought to be the ones used by a Ming dynasty Daoist called Feng I-Yuan. It is said that Feng I-Yuan used his methods many times but was never defeated.
They are said to consist of nine death points, nine knock out points, nine paralysing points and nine pain points.
The Bubishi gives advice on the use of these points but cautions against using them in any but the most extreme of circumstances.
One of the most controversial articles in the Bubishi is the one that refers to the death touch.
Article twenty-one contains twelve diagrams that detail various acupuncture points and the time of day that they should be struck in order to cause death after varying time delays. These time delays range from a few moments (“the time it takes to take seven steps”) up to three years
This is the origin of the stories of Death Touch, Dim Mak, and the "Five Point Palm Exploding Heart Technique"
I have explained separately why this sort of thing as a working technique is nonsense, but most likely had a tactical value
