Ningmaojin (Twisting the towel). Lock the forearm as one piece, use the elbow to drive the forearm.
Pair training. The partner gives resistance, first use elbow, get stuck, then use the spine/dantian. Shifu touched my mingmen and right away I can feel power from kua and the middle rod able to rotate.
Nian, 捻/碾, grinding. Push the elbows to the ribs, rub the waist with elbows causing the centre to rotate. The external drives the internal. Later on, the internal can drive the external, Dantian/central rod drives the elbows. Two gears. Demonstrate with two flasks and a piece of paper.
Six Sealing Four Closing. I held shifu’s forearm. Shifu put my front elbow in position and that was very uncomfortable, feels like it is a position I haven’t trained on. Once in position, shifu asked me to use my rear elbow, lock, then turn with the waist.
Train Six Sealing Four Closing in moving steps. The angle of front hand and rear foot should be aligned. My waist turned too much. It stayed horizontal and there was no power transfer. The power dissipates, there is no bite of the gears. The horizontal move need transfer down to the feet.
Train Pounch Covering Hand with rubber band. Lock everything, drive with the kua and grind the foot.
