Ok so i just read the book "Kung fu: History Philosophy and technique" by David Chow and Richard Spangler. And in it they describe various forms of Hard and Soft Kungs. I've pretty much heard of all of them (Iron Fist , Iron Forearm, Iron Shin, walking softly, Dragon claw, leaping kung, bag kung, etc etc.) except for Red Sand Palm. Supposedly if mastered this Kung will allow the person to kill or severely maim from just "rubbing" the enemy in a certain way. Death can be immediate or it can take as long as two weeks. Being the westerner that i am I must question the reality of this. Are there any masters that practice this or have there ever been documented evidence of it happening in the past? Or is it something that just developed from legend? Oh ya and it supposedly takes around 10 years to master.

Just wonderin if anybody has heard or knows anymore info on this.

Thanks
