Wing Chun is clearly a close quarter striking art…
precisely because the punching/striking structure requires one’s centerline to basically face the opponent’s center-of-mass DIRECTLY…
so the shoulder torque is minimal as compared to say a boxer’s lead, cross, hook, uppercut, etc…
since wing chun prefers to have both arms in play at all times for both offense and defense, ie.- simultaneous (or near simultaneous) blocking and striking, parrying, deflecting, and of course to stick to the opponent so as to apply constant pressure in order to take his space away.
THIS IS ALL DONE SHORT RANGE…
with chi sao as the main drill at the closest of striking ranges, kiu sao and other drills at a longer extension, and some non contact starting point drills and applications come into play as well, ie.- several footwork patterns, possibly the TWC entry technique, etc.
All of which can work fine at a range wherein within one short half step or so you can now strike, stick, knee, elbow, sweep, possibly standing armlock, etc…
and of course, at slightly longer ranges wing chun makes use of some low to mid level kicking…
but outside of these ranges, and when up against a skilled fighter with longer arms, indeed there can be trouble getting to range and/or in dealing with arching (ie.- round, hooking) strikes and kicks…
and trouble at the other end of the spectrum with the striker who suddenly becomes a grappler and seeks to grab your arms, body, leg, etc. for a tie-up to lock, or a take down/throw or a leg shoot.
No need to constantly debate these things…
actually working against people skilled in other arts will take the wing chun world a lot further than the debates…
which requires less attention being paid to the politics and history of wing chun and more time spent in engaging a worthy opponent or training partner.
Now as regards Alan Orr as an example of the bigger issue of what is and what is not wing chun…remember, wing chun is primarily about HITTING THE GUY…and not about how often you do lop, or pak, or bong, or tan, etc…
as long as he’s getting hit a lot more than you are.
