It was thought by many people that this was lost and no longer taught within Sun Style. But teacher Lei Shi Tai has knowledge of this form and though I never learned the form, I was shown the movements by him and they resembled the energy used in the 5 element fists, but developed it to a higher degree. As the idea is to put the energy into the spear and so project it out of the body. I have done a lot of spear training previously with Master Chu so this concept was not new to me, but in the Sun style it is projected in a natural way not forced. So this is a very high level of training, as you need to be at the ‘An Jing’ level to be able to put the energy into the spear without injuring yourself or forcing the energy and you must use the mind with intent to get the correct result.
