"Finding Equilibrium"

Master Yip Man used to practice the Wing Chun first form ("Siu Lim Tau"/"The Little Idea") one legged. It's a great way to work on one's balance which goes into the realm of footwork and terrain (most important).
I find working on finding the equilibrium in balance helps me with the Wing Chun kicks.
The "hook-step" is a deadly move to stick, trip, pin down the enemy from the feet; i learnt this during my time under the brief tutelage of one Wudang Taoist Priest up in the Zi Xiao Gong/Purple Cloud Palace. It comes from the sister martial art of Tai-Chi, called TaiYi Wu Xing Quan (Five Element Fist of Supreme-Unity). I visited Mt Wudang with my Father, alongside some other family friends, in 2010/2011 and we were very lucky to have the private use of one of the Temple Courtyards for our two week training. I'll tell you that story another time.
I am also working on simultaneous attack and defence (hall mark of Wing Chun) combos on both sides; more specifically i am working on what is known as "shoulder checking", whereby i neutralise the opponent's next possible attack (though i may not know where it's coming from or what form of attack it is, or what vector etc) by attacking right at the hinge/fulcrum point of the exposed shoulder of my imaginary opponent.
No need to memorize techniques when you can maintain dominance over and inside your opponent's centerline, whilst blocking/neutralizing any incoming attacks before they even arise. Always one step ahead.
