ANALYSIS

Movement 4 and 5 introduces you to Wing Chun's basic stance. I can't stress enough the importance of learning and developing correct stance. Although Wing Chun's basic stance looks lame compared to other styles, it is nevertheless strong, efficient and practical. Unlike other stances that require you to estimate feet distance to shoulder-width, half shoulder-width, shoulder-width and a half, double shoulder-width ... WC uses only one size, based on your personal body proportion. The size of your feet will determine the width of your stance. It makes good sense because we walk on feet, and have developed a comfortable walking step-width for ourselves according to the size of the feet we have. Small feet will take small steps, and big feet will take big steps, regardless of how wide your shoulders are. If you doubt my statement, let's look at an exaggerated situation. Say you were born with very large feet ... like a clown. Do you think your steps would be shoulder width? You'd most likely trip over your feet every two steps if you walked like an average built person. The solution: Big steps.
WC stance is based on your natural walking width. This makes the stance efficient because you are most comfortable with that width, and can move quickly with it. More or less will require adjusting and thinking about it. Having to think about your stance or footwork will slow your action down.
Movement 4 and 5 thus uses your feet width to establish your stance width. This is your beginner's basic and training stance. You will unlikely use this stance to face your opponent, but use variations of this stance that you will learn later, which you will find more comfortable and less vulnerable). Having said this, let me point out to you that this stance is not only a training stance for beginners, but also for the very advance WC practitioner. It allows the practitioner to attack from either or both sides of his body like the double-gunslingers of the old West. You'd have to be a very proficient WC practitioner to feel confident using this stance in a fight.

Spread Heels
Closeup Spread Toes CloseupThe stance shown by Sifu Chan in Figure 4 and 5 is a little high for beginners. Sifu Chan has practiced WC for 35 years. He has developed a comfortable height for his stance that he feels efficient with. It is based on his proportions. I strongly recommend beginners to lower the torso and knees as low as possible, as shown by the cyborg in Illustrations on the right side. This stance is often referred to as the "squeeze-locking the goat's head" stance. Get the picture? If you're not a shepherd, and can't imagine what I'm talking about, you may remember squeeze-locking your younger brother's head in one of your rumbles, or holding a grocery bag between your thighs while looking for the house or car keys. Legend has it that Lady Wing Chun could lock anything (like an opponent's leg) between her knees and render it freeless and helpless.
In the beginning, I would suggest you to put a football or hard pillow between your knees or thighs, and hold this position through out the Siu Lim Tao set. Even if you have strong thighs and legs from weight training, you will find it difficult to hold this position long. This is because you have not trained the muscles required for this position. Many of you will find your legs and the whole body trembling when you do this for a long while. It is a good sign, do not relieve the trembling by raising your stance height. Qigong artists try to achieve natural trembling to raise their level of training. When you tremble, it means that your inner Qi is moving to break through the blocked channels. When we don't regularly use certain parts of our muscles, nerves, and brain, the Qi channels for that area get blocked. When you start using those parts, the Qi begins to move through those channels. When it encounters blockage, it tries to break through. Eventually, it does; and the Qi begins to flow smoothly through.
I'm sure you have experienced trembling before when you had vigorously tried to get back in shape after a long rest from physical training. You may have even felt dizzy and faint. You may argue that those symptoms are caused by increased heart rate, lack of oxygen, poor blood circulation, poor balance of red and white blood corpuscles and exhaustion. Correct. However, the Chinese sees them as symptoms caused by poor Qi circulation. Good Qi circulation provides oxygen and nutrients to your body; it regulates the heart and blood circulation; it balances your blood corpuscles; it provides you energy; and it maintains your immune system.
Our immune system not only prevent and fight alien elements, but repair our bodies as well. It will cure just about anything. You get cut, and the system will repair. You could lose a limb, and the system will repair--short of growing a new one. Keeping the Qi in good running order maintains the immune system. Siu Lim Tao includes Qi training for the beginners and the veterans.
The Chinese don't use the word "stance" in martial arts. They call it the "horse." This is very significant. Martial art was not developed by the common people for common brawls. It was developed for warfare by the echelons of China. It is thus called "martial" art, rather than "boxing, wrestling, etc." In the old days, the horse was the armored fighting vehicle for the high ranking and skilled officer. You had to be a skilled foot soldier before moving up to the ranks of a cavalier. On a horse, you will not only use your weapons to fight your opponents, but use the horse as well. You will need to control the animal while fighting another cavalier or foot soldier. A war horse is no ordinary horse. It must be strong, swift, obedient, yet a little on the wild side. The battleground isn't a place for the feeble. The horse is also trained to battle other horses on the field. You, as a cavalier, will need to control your horse to do exactly what you want; otherwise, you are dead meat.
There is a saying that Chinese like to use when an emergency crops up, and what you need to resolve the problem with, which you always have onhand, is not available. The expression is, "Zhang Sigui's horse!" This express is the short version of "Zhang Siqui's horse, during an emergency, went out for a piss." The saying stems from a historical event, of General Zhan Siqui, whose horse disappeared just when he needed it, which cost him his life. The comparable English expression would be, "Getting caught with your pants down."
In martial art, your stance is comparable to the war horse. In order to use it as a fighting vehicle, you must train it, and train yourself to control it. You must be able to fight with both hands and control the horse with your lower torso. You must train yourself to stay mounted. Once you fall off the horse, you are no longer a cavalier. While you may be a skilled foot soldier, and fight other foot soldiers off, you will have difficulty fighting a cavalier. You are not only fighting a man on a horse, but fighting the horse as well.
When learning martial art, you must think of your lower torso as your horse. In Wing Chun, attacks to your lower torso is taken care by your horse. You do not bend or drop your upper torso to block an attack to the horse. The horse is trained to take care of itself. The horse is not only trained to defend, but to attack as well. The horse attacks other horses, not the rider. Does that make sense? Can you imagine the cavalier hanging below the horse's stomach and fighting foot soldiers; or the horse trying to strike down the rider with its legs? If they did that, the rider and the horse would be confused with each other's role during battle. When you are playing doubles in tennis, if you cross over to your partner's court, there will be confusion as to who will hit the shot. Wing Chun style takes care of the upper torso with the upper limbs and the lower torso with the lower limbs. It does not see sense in you using your legs to kick an opponent's head or using your fists to punch the opponent's knee.
Those of you who have done styles such as Taekwondo, will need to concentrate extra on grounding yourselves when learning Wing Chun. Your habit of bouncing and jump-kicking has trained your main Qi to reside in the upper torso area. You will need to learn to store it in your lower torso, in the Dan Tien area, which is about three fingers-width below your belly button. (See Lecture on Qi Force and Qi Balance).
Staying grounded is a strong aspect of the WC style and concept. Not only will grounding maintain your balance, but strengthen your defense and attack. Remember earlier on in this section, I mention about how our body works like a car-jack. I mentioned about the indirect winding force of the car-jack crank likened to the inner Qi force. Let me expand on this now. Direct force, although the strongest, is not always the best to apply in all situations to accomplish the optimum result. Here's one example to prove my point. Suppose you've got your small car's bumper pressed against a mid-size car's bumper, and you revved up the engine to 5000rpm on 3rd gear, equivalent to 100km/hr on the road, and the driver in the mid-size car revved his car to whatever it takes to run his car at 100km/hr; what do you think will happen? Your guess is probably the same as mine; that your small car will be pushed back even though the two cars' output are the same. This is because the mid-size car has one more force added onto the pushing force; i.e. gravity, or weight as we may commonly call it. So, if your objective is to move the mid-size car back, and not necessarily backward, you can put your car's bumper at a point on the side of the mid-size car, in an acute angle, and turn the mid-size car around with less force than the initial output.
Here is another example. You've got a truck that needs to make a turn in the warehouse, but is having trouble moving because it is overloaded. Your small car isn't able to budge it when it is standing there in neutral position, due to it's shear weight. However, if you can get the truck powered up to move a little, you can help turn it easily by pushing your car against its side.
The two examples above are similar with a slight difference. The former one shows how you can divert a powerful incoming force more easily by side-swiping it than going head on. The latter example shows that it is easier to side-swipe an object if it is moving than if it was stationary. The two examples also show how you can use your opponent's force to your advantage in martial art.
The results of the two examples above are based on one crucial factor; that the two cars are on similar grounds. This is to say that if one car was on oily surface, then it would be at a disadvantage.
In martial art, staying grounded is crucial. Whatever direction you apply your force, you need to be grounded. If your legs are not grounded, they are like the spinning wheels of your car on oily ground. Even if you were the driver of the mid-size car, and driving against a smaller car head on, you will be pushed back.
Now, getting back to the cranking force of the car-jack; we don't have any bodily parts that we can continue cranking. However, there is something we can crank; i.e. our Qi.
The universe exists on an invisible circular force. All heavenly bodies are round, spins on its own axis, and around other bodies. All martial arts work on the principle of circular force one way or another. Some use large circles, like Taiji and Shaolin, and some use small circles, like Wing Chun ... yes, Wing Chun also. (I will explain how as I touch on different movements of WC.) Some styles that look totally linear, still use the principle of circular force by twisting their fists in a straight punch.
As I said, we cannot crank our bodily parts like a car jack, but we can crank our Qi. We can control our Qi to move vortically or linearly like water. We can make it explode or implode like gas. Now, why am I talking about circular force and Qi when I'm on the subject of WC horse? Here again, I'm trying to stress the importance of a strong horse, and how you, as a small person, can apply the principles of circular force and Qi to fight your opponent to your advantage.
As mentioned before, your spine is like the center shaft of the car-jack. The crank turns the shaft to move the levers up or down. Now, imagine your spine as a big, heavy duty spring (winding force). Imagine bolting the spring to the ground firmly. If someone was to push down the spring; the more pressure he applies to the push, the stronger the spring will rebound. The spring is only effective if it is grounded well. If the bottom were to slip, there will be no rebounding force.
So, if you do not learn to ground yourself firmly, you will not be able to rebound your opponent's force; therefore, you will not be able to optimize your force.
Note: Those of you who find it difficult to imagine yourself as a giant spring, imagine yourself as a dumb car-jack. Imagine your spine as a spring-loaded shaft, and your limbs as the levers. Grounding will mean bolting the bottom of the shaft and levers to the ground. Pressure applied down on the levers will create counter force upward. How's that for analogy? Need more explanation? Can't help anymore! ;-)
What makes the WC horse look lame is the toes in position. You are reminded of the high school nerd who was pigeon-toed, and walked silly; but how did he turn up to be a sex machine and the corporate president of the company you work for? Kidding aside, there is something to being pigeon-toed. Qigong practitioners do meditation with their toes turned in. Many high-level practitioners train themselves to walk pigeon-toed. Turning your toes inward contains the Qi within and around you. When you learn to store your Qi in the Dan Tian (lower abdomen and pubic) region, you will not want to leak it out by spreading out your toes and knees. Once you have grasped the concept of the Qi, you will feel the difference between turning the toes in and turning them out. Turning the toes and knees inward create invisible doors that will contain the Qi. Turning the toes and knees out will open the doors. If you have been practicing martial arts for some years, and wasn't aware of this, you may feel it right away, now that you're exposed to this concept. Even if you haven't given much thoughts to Qigong, you have been doing it unknowingly. You have learned to build it and use it from the training you got, which the early developers of the art had included in the design. Being unaware of it, you have not learned to control it.
I believe Tyson used it unknowingly; therefore was so powerful during his prime years. However, not being aware of it, and not knowing how to control it, he lost it in the later years.
Try this experiment: Stand with your toes and knees turned in for awhile. Imagine an invisible wall encircling around you, from waist level to floor. After three minutes or more, suddenly open up your knees and toes. If you will feel a burst of energy escape from your lower region, great ... you're already feeling the Qi; if not, work on it.
Here's a free tip worth millions of dollars. If you are having trouble getting your wife pregnant, and you walk with your toes wide open; start walking pigeon-toed. It's worth a try, especially after dishing out tons of money to your doctor with zero results. Walking wide-toed disburses the energy in the pubic area. Your sperm production is low and weak. Drop me a note of thanks if it works. Don't hassle me if it doesn't!
WC has only one horse. It appears to have more only because it switches sides and looks different from the opponent's perspective. When the horse turns to one side, the foot of the turning side pivots on the heel, and the toes move to the maximum point of parallel alignment to the stationary foot. It is important to understand that parallel-feet position is the maximum your feet should spread apart. It is still best to keep your toes turned-in, even if slightly from the parallel position.
The toes are turned in for the WC horse for a few other good reasons (besides getting your wife pregnant). Turning your toes in turns in your knees. This position protects your pubic area, or allows quick reaction of your leg to lift to a protective position. It protects a very important and life-threatening Qi meridian located at the bottom of your pubic region, called Huiyin, which is located between the anus and the testicles in a man, and between the anus and the posterior vulva in a female. That point should be highly secured. Getting the Huiyin kicked is deadlier than getting the testicles kicked. Not saying that getting kicked in the testicles will have little or no effect, but that it will not kill him. Damaging the Huiyin can kill him. As for the testicles, only a male struck in the testicles knows what it's like. Ask your cross-eyed buddy how this eyes became that way. If he can't tell you, ask the guy who's crunched over, with golf balls in his mouth. Joking aside, the pain is crucial. You get a momentary trip to the stars or the black hole. Regardless whether the target is the Huiyin or the testicles, one should prevent a strike to either places.
When a male turns his knees inward, the testicles are pushed behind the inner thighs--a good place for the twins to hide (especially if you want to get your wife pregnant).
Now, you may not see any sense in what I'm saying when you see yourself in the WC horse position in front of a mirror. You feel vulnerable facing your opponent in this position. This is so because you are new to this horse. Only the very advance WC practitioner will feel comfortable on this horse. However, if you were to step one foot forward towards the invisible line drawn (perpendicular to your body's centerline) on the floor, you will see how the front leg (especially your thigh and knee) protects your pubic region. Now, you feel like Fort Knox, don't you?
Here's another reason why the toes are turned in. Try this experiment: Stand with your feet positioned parallel to each other. Gradually spread your toes out. Continue spreading as far as they will go. If you were standing at the edge of a pool, with your back facing the water, you'd have done a back splash, and would be swimming in it now. Reverse the experiment by standing with your feet parallel to each other, and slowly turn the toes in as far as they will go. If you were standing at the edge of a building looking down at the traffic, you'd be swing your arms desperately backward to prevent from falling forward. What's the point?
Wing Chun, although seemingly gentle, is a very aggressive style. No, not in the sense of big and strained moves, but in a silent assertive way. WC trains you to always exert energy forward. Trains you to be the aggressor. You become the strong and steady bulldozer. You hardly retreat from incoming force; you utilize it to divert against itself. The toes-in position facilitates you in forward charges, as demonstrated in the experiment you just did. The toes-out position facilitates you in retreat. The next time you watch a boxing match on TV, watch the boxers' footwork. The one who has his back foot turned out (pointing back) will be the retreater; i.e., he will be backing up most of the time. The one who has his back foot pointing forward will be the aggressor. Although they were not trained to point their toes in either direction to fight aggressively or defensively, their brains automatically adjust their feet according to their psychological makeup.
Here's yet another reason for turning your toes inward for the WC stance. First try this experiment: Stand with your feet parallel to each other. Pivot one foot outward on its heel. If you are flexible enough, you could probably turn the foot 180 degrees. Try this next: Bring the foot back to the parallel position. Now pivot the foot on the heel slowly, turning your toes inward. The most you could probably pivot is 45 degrees. Try holding the foot there for awhile. You will notice that your foot wants to spin back to the original position.
By creation or evolution, our feet point forward to facilitate us in walking or running forward. Our leg muscles allow us freer rotation outward than inward, because we have more use of outer rotation than inner rotation. By turning the toes inward in the WC horse, you are grounded stronger than if you turned your toes outward. (You are scratching your head, and asking, "How's that?")
In the last experiment, you noticed that your turned-in foot wants to swing out. This creates friction (your foot against the ground). It's like those guys you see carrying a large sheet of glass. When they apply the whatchamukolit suckers on the glass, they do it with a twist to ensure a tight grip. Your feet, when twisted in, grips the ground. Your leg muscles in this position are twisted in, wanting to rewind. Your feet and weight stops them from rewinding. Your feet's outward pressure against the ground creates a tight grip. Not only that, but you become more aware of your feet on the ground; in other words, you are grounded. Elementary, Dr. Watson!
Feeling your feet is an important factor of grounding. The higher you keep your Qi, the less you will feel the ground, and the less you will be grounded. Not being aware of your feet on the ground is the same as not being grounded. It's like riding a horse without stirrup, or a bike without pedals. As soon as you press your foot against the stirrup, (or the pedals in the case of a bike) you will feel connected to the ground. As you know, we have electricity running through our bodies, carrying messages to our brain. When your feet are not in contact with the horse, or a conductor connected to the horse, the electrical current will not flow. When your feet contacts the stirrup (conductor), and are pushed down, the current is allowed to flow freely through the horse to the ground.
When you are on the WC horse, you will notice that the more you turn your toes outward, i.e., releasing the tension, the less you will feel attached to the ground. When you have released the twist to the point of parallel feet, you have reached the neutral point. For a moment, imagine your feet as the two reels of a cassette tape, and the tape ends are tied to your toes, and the tape is wrapped along the outside of the feet and behind the heels. The parallel (neutral) position represents the tape with no taut or slack. Turning the toes in tightens the tape tautly. Turning the toes out past the parallel position slackens the tape. So, the tighter your feet are twisted to the ground, the tighter you are gripped to the ground; inversely, the less you are twisted to the ground, the less you are grounded.
If you are still not convince about the strength and benefits of the pigeon-toed horse (strange looking beast), here's one more scientific fact: If you take a bird's-eye view of a person standing with his feet positioned parallel, you will see that his body structure is standing on top of a rectangular area formed by his feet. Think of the rectangular area as a box, and raise the box one meter high. If you were the person standing on the box, you probably won't feel so secure, because you are standing on a pretty narrow area. If the box was to be moved sideways, you will have little trouble maintaining your balance, because your base is wide in that perspective. However, if the box is moved forward or backward, your balance becomes critical due to the narrow base in perspective. Now, take a look at a person standing with his toes turned in from a bird's-eye view. He has formed a triangular area with his feet. His heels have formed the base of the triangle. His toes have formed the third point of the triangle. In this position, he has mounted his body structure on a tripod. If you know a little about photography and the concept of the tripod, you will understand how firm a tripod can ground itself. You will know to secure the tripod by aligning two legs parallel to the back of the camera, and one leg stretched forward to where the lens is pointing. The camera is sitting in the center shaft of the tripod. Any weight applied on top is distributed to the legs. The center of gravity remains on the center shaft.
When doing the toes turned-in stance, your center of gravity remains in your centerline, which is driven down to the ground perpendicularly. The human structure is built in such a way that the heels support 60% of one's weight; 30% goes to the balls of the feet, and 10% to the toes. It makes sense to form the base of the triangle with the heels.
If the triangular block was raised one meter, with you standing on it, you should feel pretty secure when the block is moved sideways and forward because you have a wide base for these directions. You might be confused to why your balance would be secured when the block is moved forward when the area between the toes are rather narrow. Let me explain. If the block was pushed forward, the momentum will tilt you backwards. This means that the back base will resist the force. It will be strong because of your wide heel base. However, if the block was pulled back, the reaction force will push you forward. You will fall forward more easily because of the smaller area your feet occupy in the front. WC sees that as an advantage, and uses it to charge forward swiftly. If your opponent pulls you, you go with the pull, and use the momentum to strike him. WC practitioners would be more than happy when the opponent bridges the gap for him. All said, the toes-in stance is not as susceptible to falling forward as you may think. With the toes turned in, any force, pushing or pulling you forward will be resisted by the triangular point (like the third tripod leg) formed by your toes. When necessary, you can use the pinnacle point as brakes to control the fall. Believe me, you can resist a forward fall more with your toes turned in than if the feet were parallel. Don't believe me? Go push a rectangular table (especially one with a narrow depth. When you've got it tilted more than 45 degrees, it will go crashing down. (Should have told you not to do this experiment with a glass table!) If by any freaking chance you've got a triangular table the same width and depth of the rectangular table, try flipping it over. First of all, it will resist the flip by moving the third leg. When you get it to 45 degrees, it will want to turn down to one of the other legs. You will get it flipped eventually, but not without extra effort.
Hope you are not confused with so much explanation. The bottom line is that the wide base will give your the most stable balance, and the narrow one the least. Although pointing the toes in will give you the least amount of resistance in a forward move, it will resist more than if your toes were parallel or pointing outward.
Some of you may argue that pointing your toes outward will also form a triangle, therefore, would give you just as stable a stance as you would with toes turned in. Let's look at the man from the bird's-eye view standing with his toes spread out. Yes, he has formed a triangle, but an inverted one. The problem here is that the wide base is formed by the toes. As I have said earlier, your toes only hold 10% of your weight. Not only that, but looking from the top, you will see that the wide base line (formed by the toes) is outside of the body structure. Your line of gravity, which runs straight down from the top of your head to the ground, is close to the pinnacle point of the triangle, where there is little room for the gravity line to move about before dropping off. Your heels, which support 60% of your weight is also located on the lines near the pinnacle point. You are surely not well balanced here. Raise the block with you standing there. Every time the block is moved forward or backward, you will be easily toppled because your heels, holding 60% of your weight, and the strongest support of your weight, are on the narrowest part of the base; and your toes, holding 10% of your weight, and the weakest support of your weight, are on widest part of the base. So, this type of stance is kind of upside down (like the triangle it forms) in principle. It's like stacking boxes in a crate, and putting the lightest and smallest box at the bottom, and the heaviest and biggest on top.
Actually, I still have a lot to say about the horse in general, and particularly about the WC horse, but I won't talk your ears off now; I will get to it later.

OVERVIEW

O.K., let's look at what you've learned in Siu Lim Tao Movements 4 and 5. You've learned:

  1. About the Wing Chun horse.
  2. About how the horse is customized to your proportions.
  3. That this horse is for the very beginner as well as for the very advance WC practitioner.
  4. Something more about Qi.
  5. About how the Qi can be converted to whirling force.
  6. How Qi can be made to explode or implode.
  7. The importance of grounding oneself.
  8. How grounding can be utilized to rebound incoming force.
  9. How to use your body to leverage against a heavier one.
  10. That the pigeon-toed stance protects your lower gates.
  11. That the pigeon-toed stance contains the Qi.
  12. That the pigeon-toed stance facilitates in forward movement.
  13. That the pigeon-toed stance grounds you.
  14. That the pigeon-toed stance is better balanced than parallel feet or toes-out stances.
  15. A slew of other factors that are directly and indirectly related to the two movements.
As you see, the WC horse is not as lame as it looks. It looks lame because of the narrowness of the width compared to stances of other styles. Visually, wide stances look strong, but are not necessarily so. They are strong in one direction only. The wider the stance, the slower it would be for mobility. The wide stance in a sense is used to intimidate the opponent. Often, when we are in confrontation with someone, we make ourselves appear bigger by bracing our arms to our sides, with our fists on our waist, like the Superman pose. Animals and birds do the same when in confrontation. Animals raise their furs, birds open up their wings. Martial artists also do it with their stances, like the Karate Kid did in that silly movie. Well, martial artists are not the only funny guys. I get a kick out of motorcyclists who spread their legs wide open to make their choppers look bigger than they already are. Their knees end up as crash bars when the bike falls.
