[QUOTE=Katsu Jin Ken;887519]Anyone know of any videos or articles that break each movement in the forms down and give explinations of the applications and energy involved? Preferebly Yip Man style but any style will be of use.
Additionally, does anyone know what the throwing wings in chum kiu are used for? and why is the same movement repeated 3 times? (im a newbie at wing chun)[/QUOTE]
free info , no dvd’s to sell sorry…
there is a common idea born from “attack as your defense”
What does the attack look like ? can I see it ? it can take on many ‘looks’ . From a simple punch to a complicated engagement requiring mixed ma’s abilities. We are a combat mind, not sporting iow, we are trying to end the fight asap , not allow it to go 10 rounds with a break in between , so we need to have a way to deliver the idea …ok attack as defense , now what , how do i achieve this great idea ? 
the forms are simply the ‘attack’ broken down, iow the forms are just ‘parts’ of the tools you need to deliver your attack as you require, no elaborate sequential movements. The forms are just ‘bytes’ of actions in a high speed engagement .
The repetition [ 3 times] signifies importance , or focus more on that particular action/s.
The bong is an energy not a pose, to recover an ‘attack’ , so we repeat the partnership
of bong & vu & leg . The ‘throwing’ is a ballistic [ging/shock] energy to displace the other guys arm laterally to the ensuing strike /attack from the rear vu. incorporating leg force unity in the timing …leg energy timed with bong position = explosive force. repeat 2-3 forever 
Bong & vu& leg, are an attack recovery action, relatively complex, beyond a simple strike that also does attack /defense actions , simultaneously. So we repeat it ..you can do it 8,000,000 times …3 is just a ‘form’…a way to do a simple set to maintain yourself alone.
Bong isnt done alone except when doing ‘facing’ aka low [ only for training] because we apply this attacking entry bong when we are coming directly at you from an angle / flank, when either rear/lead leg can be used .
We do the bongs in SLT from left to right & right to left alone . In the Chum Kil, we incorporate the rear X angling strike line of vu , with the displacing energy of bong , coupled with the short shuffle that uses the leg extension in timing to match the bongs final ballistic point of ‘contact’ or not and back to recovery.
This allows the strike ‘attack’ to be delivered uninterrupted by someone simply X’ing over your initial striking attack arm. The combined energy of the action is ‘contained’ into a move that doesnt chase but recovers back to keep striking , meaning even if you ‘miss’ the contact point you dont go past your own centerline opening yourself up…knives.
Bong is done because a spatial line of attack is coming at you , meaning you dont require contact to ‘feel’ anything to use it , many erroneously use the bong to divert force , turn energy and enter into another realm of fighting…feelers.
You can fight a ‘feeler’ quite easily , because they seek arms to feel to function …
If an arm ‘finds me’ then I use feeling ‘briefly’ ;), otherwise I’m striking you, its up to you to stop me , how good you can do that is your attack ability… Do you have counter attacking actions that work to attack my attack, to overwhelm my intentions to attack you ?
can your simple tan punch and jum punch delivered in rotation , work to regain your attack ? or do you require two hands for everything..ie lop n chop, lop n punch , lop n bil…pak n trap n punch, bong lop chop, bong lop punch and the list goes on kwan lop n chop:eek:
Even if I show you a movement in a dvd , without certain ‘thinking’ to guide you it will seem very similar .
In a real fight you will act without thinking about VT …so the VT has to be done in a drill that can take the actions and responses to a level of 'no thought '…you cant achieve this in forms alone doing 3 times , so we do chi-sao to ingrain the ideas .
The Wooden dummy gives us the ‘ging/shock’ force points and alignment /facing with rotation of actions not ‘poses’ isolated into ‘moves’ …
If you can just step away from the attacker and make them lose contact …stop moving and make them lose space and get to close …how to regain your space to attack, maintain the attack if grabbed, if an arm x’e yours, if you need to kick …
everything in the system is training you to be able to achieve this goal…
tan is the 1st 1/2 of a punch as is jum…each can use the other to maintain an assault on either flank, without leaving your centerline to ‘block’ [ hate saying that] or chase to feel :D…
‘throwing bongs’ work to keep this flanking attack going , because either bong ‘knocks’ energy left or right , further opening up you ability to strike into the gap created or simply deliver attacking actions…
So either arm has a tan strike ability, using the outside of the arm [ elbow leaves the line or sreads off the line]
Either arm has jum strike ability , using the inside of the arm [ elbow inwards strike]
added …the ‘fixed elbow principle’ refers to the fact that the arm uses either side of the forearm with elbow control fixing the line , as SLT , so the arms dont leave the line when doing tan or jum, only the inner mind control focus is changed to keep the elbow in and strike, or allow the elbow out…starting and finishing from the centerline. Each rotating back to a rear chambered strike, capable of being either energy in a millisecond of a changing fight …no thinking .
each can deliver a strike to back up the previous ‘energy’ delivered outside /inside strikes from either side seamlessly…not seeking to block but deliver deflecting ‘glancing’ energy as they go forwards…bong serves to open the door left or right depending what side your on…
brilliant idea.
some will say there is a high -low - turning etc..bong …bong is just a means to an end so dont get caught in the " this bong is for this , and this bong is for if this happens…
whatever you do, point your centerline at them and ATTACK,FIRE, SHOVE , PUSH , KICK, HEADBUTT, RAM INTO WALL.. !!! he hehheheh …never let them point their line at you, the rest comes from this simple thinking …2 lines dont face each other unless they are training partners doing drills to attack or counter from that ‘face -off position’
..you wouldn’t want to have a fair fight would you ?
fight 50 of the opponent with 100% of yourself. Which 50% is up to them to show you… what side doesnt matter because your training to be able to deliver 100 % from either side they turn or you make them turn ; )
