I would like to ask how many points you have tried. It could also be due to the five elemant side, If the points being attacked work towards a constructive cycle due the body type it will cause little effect. IE: Fire burns metal, metal cuts wood. I find all points do not work on all people. Also how long to you tweak the point the student may e blocking the pain easy to do , how ever it does not work for more than a few moments.
