There’s a subtle distinction between using force and… using force. Up to this point I’d been under the impression (ok, it was my mistaken belief) that you shouldn’t use force/strength under any circumstances – unless you were finishing off you’re opponent. I realised at a class today that it’s not quite as simple as that. And yet it’s not much more complicated either.
If I’m face to face with someone and I try to push them out of the way, this is bad. I’m using strength to overcome them. But if they are walking backwards already and I simply add my weight to their movement by guiding them backwards a little faster, this is good. Similarly if someone charges towards me and I charge towards them, that’s two equal and opposite forces meeting in the middle – bad. Bang bang. If someone charges towards me and I slip sideways and then my deft push adds to their momentum to send them on their way – in the same direction – good.
So using strength isn’t always bad. We did a couple of drills today that really made the penny drop for me. They both started with me pushing my bong sau against my partners fook sau. The bong sau actually changed to a lan wan sau (bar arm thing!) to do this and the action was merely to get a response from my partner – that response being his resistance. When he met my pushing bong sau with his own unconscious resistance, I could use his energy by rolling my bong sau on the inside into a tan sau. But because he was pushing back against me, I could actually help his arm go in that same direction with my tan sau, so the tan sau pushes his arm in the direction it’s already going. This is the use of force that isn’t bad. His fook sau is already going in that direction because he’s resisting my bong sau, so it’s ok for me to help it along with my tan sau.
Does that sound complicated? It’s not at all, but of course trying to string a coherent sentence together that describes the movements is tricky. I really need to video these things to illustrate. But saying that… it’s actually quite useful for me to articulate what we did, and write it down, because it aids my memory. Maybe I could do both 
The next drill used the same setup. The old “bong sau pushing forwards against his fook sau to provoke the resistance that we can harness” trick. Sneaky like a ninja. This time, when I felt his resistance I had to lap sau it out of the way with my other hand, trapping his tan sau in the process. My lap sau is almost coming back towards me and I have to move to my left to get the angle (assuming my right arm is the bong sau). After the lap sau comes the punch of course, but the important bit is creating the space in which to punch.
These drills really illustrate the subtlety of wing chun. Redirecting energy, you have to love it. The pushing bong sau doesn’t have to be that strong, and people invariably resist it without even knowing they are. This resistance is most accommodating of them, because without it the technique won’t work.
Recently I was messing with my girlfriend (who doesn’t do any martial arts) and we were facing each other, long wu saus touching at the wrists, I would pak sau and punch blah de blah. Well after a few goes, when our wu saus met, I could really feel her pushing against me. Of course she didn’t know she was pushing until I quickly moved my hand away and her hand flew to the side because I was no longer resisting it! I’m always being told to stop pushing, and I know I’m much better than I used to be.
I wonder how much of your partner’s energy you just don’t notice. Energy that you could use to your advantage but is just going to waste. I know for a fact that I’m not yet tuned in sensitively enough. But then, who is?
On a side note, if you want to see numerous examples of how not to use strength, search youtube for chi sau competition. Some of that stuff is not that far removed from wrestling! It ain’t pretty.
