In Tsum Kiu the sequence of Jeun Ma進馬, Taan Sau攤手, Dai Bong 低膀手 ends with both feet together after the 3 steps. Many people ask what this is for. The answer is actually it has no meaning it just makes the form tidy and neat. We should never put our feet together if we have to fight as this is very dangerous.
In many traditional Chinese forms there are extra movement added to make the forms flow and look good, but there is no real practical side to these movements. Also after the final Dai Bong we do Biu Ji標指, and this requires some Fa Ging. Quickly bringing our feet together creates some of this power for the Biu Ji, the Jat Sau窒手and Yan Jeung印掌.
After finishing the Yan Jeung we turn around by moving the right foot back, keeping the right toes on the ground, at the same time we keep the weight on the left leg. We then turn on the toes if the right foot and the heel of the left foot. This turns us 180 degrees and then we shift the weight so that 70% is on the back leg and 30% is on the front leg this also creates the Jeun Ma position, with the feet shoulder width apart. We then repeat Jeun Ma and finally turn back to face the front and our stance becomes Yih Jih Kihm Yeung Ma二字鉗羊馬 and our feet are once again shoulder width apart. This is an important part of the skill we need to maintain the shoulder width distance between our feet with every stance in Wing Chun training.
