"Silk -Reeling Exercises in Taiji are a set of repetitive spiral movement exercises with emphasis on --- the ground connection, waist connection, knee alignment, kua sinking, opening and closing of joints and dantian rotation. These continuous spiral movement are the basic components, the foundational building blocks of Taijiquan. This series of spiral movement exercises are for the development of the basic strengths and coordination of Chen Taijiquan. These exercises will increase the mobility of body joints and relax the muscles and tendons of the practitioner. The spiral movements will open up and exercise the 18 major joints (in sequence from the head to the ankles) of the body, promote muscle relaxation and flexibility, and reduce physical tension and strain."

"The words in the second internal circle (outside the little Yin-yang symbol) are: Ke Nian (Restraining Thought; on the right), Wang Nian (Deceitful Thought; on the left), Si Nian (Personal Thought); then, following the spiral, are: Bailu Haoran zhi Qi (White Path Noble Spirit), Heilu ji Xue Qi (Black Path is Animal Spirit), Rensheng zhi Yinyang (Yin and Yang of Human Life), Tiandi zhi Yinyang (Yin and Yang of Heaven and Earth), Taiji zhi Yinyang (Yin and Yang of Taiji). 

The first white path and black path are like Taiji Yin and Yang existing within Wuji (Limitless). The second white path and black path are like Taiji that gives birth to two Yi; these two Yi are Yin and Yang, e.g. Heaven and Earth. The third white path and black path are like Qi of Yin, Yang and Wuxing (Five Elements) that every man has and needs to live. The fourth white path is what Mengzi called Noble Spirit (Haoran zhi Qi); black path is man's Animal Spirit (Xue Qi, literally Blood Qi) which, if joins Morality and Justice (Daoyi), becomes Spirit of Righteousness (Zheng Qi, literally Upright Qi), e.g. Noble Spirit. The fifth white path is the Mind of Dao (Dao Xin), the one that governs Qi. Qi can not move without Principle (Li), this Principle is within one's Character (Xing). Black path is Human Mind (Ren Xin), what sages and men of virtue called Personal Mind (Si Xin). White point inside is Restraining Thought (Ke Nian), while black point is Deceitful Thought (Wang Nian). Only saints are able to keep Restraining Thoughts only and get rid of Deceitful Thoughts. Deceitful Thoughts are what Gaozi called feeding sexual desire (Si Se Xing). All humans have them. If a man could get rid of these selfish thoughts so that they would never appear, then (he would be) of pure heavenly nature (e.g. of pure primordial nature). (If one is) of pure heavenly nature, then while practicing boxing one would move following Nature's Mystery (Tianji), naturally, lively, the original shape of Taiji would be unintentionally revealed in my body.

The three big external circles advance Yin and Yang from their beginnings; three internal circles say what Yin and Yang are being governed by. Three internal circles, e.g. what a man receives, are all within third circle, and originally there was no need to draw any further circles. (However since I) was afraid (that people would) practice boxing without understanding the principle of Qi governing, so there had to be another picture drawn, and (I tentatively) draw it to make it easier to understand. What is important is that three internal circles are all within third circle, third circle is within the second one, the second one is within the first one. This drawing explains particularly the core of guarding life (Wei Sheng), wonderful formula of Qi returning (Huan Qi). (If one) is expert in moving Qi (Yun Qi), only then one can guard one's life; if one can guard one's life, then there is support for one's Character Restoration (Fu Xing), and Qi can rely on (this). Such Taiji Boxing is a study beneficial for body (Shen) and mind (Xin), character (Xing) and life (Ming). Sages say that cultivating one's moral character lies in Character Restoration, which means guarding life and moving Qi are the core of cultivating one's moral character and restoring it. (I do) not know (if this is) correct or not, for the time being (I gave) illustrated explanation to make it more funny."
-   Illlustrated Explanation of Silk Reeling Essence of Taijiquan.  By Chen Xin (1849-1929).  Translated from Chinese and edited by Jarek Szymanski, 1999.  

"Silk reeling energy' is common in most all the Northern Chinese martial arts. It refers to moving the torso and limbs in circular, spiral or twisting patterns. At a basic level (striking for example), the greater the speed, the greater the potential force of impact. In the body, this translates to combining and coordinating the overall movement of the body so that the combined power of several types of movement is many times greater than a single type of movement alone. For example, if I hold my arm straight out ahead of me and walk directly into you I will hit with x amount of force. If I combine the forward movement with a rotation of the torso (y amount of force) as I hit you, the force will be much greater (x and y combined). The method of silk reeling is to combine the many rotational forces of the body into one coordinated flow (the rotational power of the legs with the hips with the torso with the arms), resulting in an exponentially greater force than could be achieved by using one part of the body alone. Another advantage of silk reeling power applied to striking is that the spiralling power issued bores into the opponent's body (just like the bullet of a rifle penetrates more readily than a musket ball). When applied to throwing, the same types of rotational body movement allow the thrower to put more force into an opponent from point blank range (which is where most grappling occurs). In addition, people are more able to resist straight pushing and pulling motions, and are easily put off their base when twisted. Joints are much more resistant to straight bending and stretching forces than they are to twisting or rotational forces. So silk reeling applied to Chin Na and joint locking techniques makes them more efficient. Twisting the joints of the extremities is the only practical way to chain lock into an opponent's center for techniques which push inward. Defensively, twisting to neutralize an incoming blow ('rolling with a punch' for exmple) is the only method of avoiding harm while maintaining the ability for simultaneous counter attack (for example, you push my left shoulder, I rotate my torso with the push, neutralizing the incoming force while simultaneously striking back with my right hand. These types of techniques are only possible when rotational movement is applied). Health wise, rotational movements of the joints are invaluable in maintaining range of motion and proper lubrication. In addition, twisting the muscles (and internal organs) helps to 'squeeze' the blood and fluids out and allow fresh blood in. Circular or rotational movements also greatly improve flexibility, and the strength of the connective tissue."

Jin:  Trained strength, connected force, educated strength, high level Kung Fu, controlled power, conditioned and skilled use of strength.

"The word Jin refers to strength, vigor, zeal, or expression of strength.  It is actually a combination of Yi (intention), Qi (vital energy), Li (force or strength), and Xin (heart referring to mind).  Insofar as its use in martial arts terminology is concerned, Jin is defined as "principles of motion or connected force."  That is, it's the result of the combination of Yi, Li, Xinand Qi expressed through physical movement.  Acquiring Jin means that you must learn correct body alignment and structure, connected expression of the breath with the application of strength, and focusing the mind on the task at hand.  When these things are united into a single entity, the result is what we might call "trained power."  ... Kung fu requires that we learn to exert force correctly, and in a variety of different ways.  This necessarily involves physical movement and li, physical strength or force.  This is power expressed through our physical bodies.  To move with speed and precision requires the correct us of strength rather than brute force."
-  Philip Starr, Developing Jin: Silk-Reeling Power in Tai Chi and the Internal Martial Arts, p. 3 

"Known as Chan Ssu Gong, these unique spiraling movements loosen the 18 joints and increase range of movement. The key to proper silk reeling is whole body movement originating from the center, the dantien, and a connection to the ground, peng jing. These exercises are particularly rehabilitative for people recovering from physical illness or injury.  
    Silk Reeling is named for the quality of movement that is practiced. It is said that the movement must be like a spider spinning a web. The spinnerette touches a branch and delicately the silk is drawn out to the next location. If the spider moves too fast or too slow the silk will break and be lost. Movements must be continuous. If an understanding of the body's potential for a natural flow is developed, silk reeling will develop into a deeply satisfying, healing, and beautiful art. 
The dantien, or center of the body, must lead all movement. Silk reeling exercises train the body to move as a whole unit lead by the dantien area. This area of the body is generally not recognized by western anatomy. It operates in Taiji as both a physical location and as an energetic center. It is important that the dantien is not associated with any muscular tension or movement. The dantien can be understood within the body several different ways and as the practitioner gains experience their understanding will improve and change many times."

"The Western “emerging from a cocoon” metaphor is an example of a literary metaphor. The taiji “mobilize jin as though drawing silk” metaphor (yun jin ru chousi), however, is a very good example of a conceptual metaphor. This kind of metaphor is different from a figure of speech, or a poetic way of expressing something for esthetic reasons. The conceptual metaphor actually has to do with thought and action, and is based on experience. It is a way of understanding one kind of experience in terms of another kind of experience. In this case, it is based upon something that was part of the cultural landscape of traditional China that many people in rural settings were exposed to from early childhood—sericulture, raising silkworms for production of raw silk. Sericulture in China goes back millennia, and was prescribed in detailed ritual. Because of the value of silk domestically and for export, the processes of production were closely-guarded. From what I understand, each silkworm produced its cocoon in one continuous strand—a very fine fiber. Silk production required removal of the intact individual fibers from cocoons and winding these into thread that was then woven into fabric. The drawing, or pulling of silk (chousi) from the cocoons was a very delicate proceedure. If done incorrectly—with too much force, or with stops and starts—the fiber would break. So, it is this imagery that taiji theory draws upon to better understand the interaction of body-mechanics and mental intent required for movement that is integrated, constant, sensitive, and smooth. The phrase chousi is a common metaphor not limited to taijiquan. It is often used to describe doing something slowly and meticulously. There are related expressions that shed light on the metaphor. One of them is “bojian chousi,” which is something like “peel cocoon draw silk.” This is used to describe a detailed inqiry into a specific sequence of events, as in a criminal investigation or a scientific experiment. It implies deep and detailed observation, similar perhaps to our metaphors of “leaving no stone unturned,” or “going over something with a fine-toothed comb.” Another expression is “dujian chousi,” roughly “single cocoon draw silk,” which is used as a metaphor describing literary work that is well-organized and clear, a thread of thought or sequence of ideas that successfully cohere. Equivalent metaphors we may use in English might be those like a “train of thought,” or following the “thread” or “line” of an argument.  The taijiquan use of the metaphor involves tactile sensitivity as well as mental awareness and concentration. To my mind, it’s a powerful metaphor."

"Chen Xin's classic book Illustrated Explanation of Chen Family Taijiquan, outlines three principal benefits of silk-reeling energy in relation to the martial application of the art.  This energy can operate as a revolving energy similar to a tire rebounding any incoming force.  The faster the opponent's energy comes in, the faster it is bounced away.  This requires the body to be full, relaxed and sensitive.  Second, silk-reeling energy can be piercing, like a spiraling bullet.  This is a powerful and penetrating energy when applied during an attacking maneuver, whether it is with the fist, elbow or foot.  Third, silk-reeling
energy can act as a neutralizing energy, teaching the practitioner how to lead an incoming force to emptiness."

"It is easier to leave a circle than to enter it.
The emphasis is on the hip movement whether front or back.
The difficulty is to maintain the position without shifting the centre.
To analyse and understand the above situation is to do with
    movement and not with a stationary posture.
Advancing and retreating by turning sideways in line with the
    shoulders, one is capable of turning like a millstone, fast or slow,
    as if whirling like a dragon in the clouds or sensing the approach
    of a fierce tiger.
From this, one can learn the usage of the movement of
    the upper torso.
Through long practice, such movement will become natural."

"When you are in a matching situation with your opponent, there are three circles of offensive and defensive domains or territories.  These circles are large circle (Chang Ju, i.e., long range), middle circle (Zhon Ju, i.e., middle range), and short circle (Duan Ju, i.e., short range).  These circles are also called rings.  In a battle, you should not stay in the same ring, which allows your opponent to set up a strategy against you easily.  Your rights should be variable, random and confusing to your opponent.  Not only just the size of the rings, but also the height of defensive and offensive actions should vary as well.  When this happens, you will generate more confusion for your opponent and this will allow you to execute your techniques effectively and efficiently."

"The idea that will be developed that in Taiji, correct strength orignates primarily from muscular extension, in with the muscles lengthen (rather than originating from contractive muscular action in which the muscles shorten).  That is, Jin will be interpreted as arising from muscular extension, which is unified, is capable of being quickly modified, results in a high level of rootedness, and enhances the flow of Qi (Ch'i).  By contrast, Li will be interpreted as strength arising primarily from muscular contraction, which is localized, is difficult to modify with changing conditions, results in balance (root) being relatively easy for an opponent to break, and tends to constrict the flow of Qi."

"These exercises are great for loosening up the joints, enabling you to enjoy freedom of movement.  Ultimately, they will also help to develop spiralling energy within the body.  These silk reeling movements benefit the joints, sinews and muscles and improve circulation.  The circular movements strengthen the connective tissues and increase the secretion of synovial fluid which lubricates the joints, keeping them supple.   People who have been practising these exercises have reported better coordination and an opening up of shoulders, back and waist."
-  Chan Si Gong

    "Grandmaster Feng Zhi Qiang (1928- ), founder of the Hun Yuan Tai Chi system, states that Tai Chi is Chan Si (silk reeling).  This statement highlights the importance of this aspect of the training.  The Tai Chi classics speak of performing Tai Chi movements like reeling silk from a cocoon.  The analogy warns us that if the silk is reeled too fast, the thread will break.  If it is reeled too slowly, the thread will tangle.  The silk reeling exercises teach you to use an adequate amount of force to generate movements efficiently.  If you are too forceful, you will lock your joints and will fail to achieve freedom of movement.  If you are too limp or empty in Tai Chi terms, you will also fail to circle the joints completely, thus losing the full range of movement.   

    The Chan Si Gong is an important training method for developing body awareness and coordination.  It is a link between building and expressing qi and jin (force)  These silk reeling movements work on different joints of the body: neck, shoulders, elbows, wrists, chest, abdomen, waist, hips, kuas (inguinal crease), knees and ankles.  Grandmaster Feng describes the Chan Si Gong as training the body’s 18 balls.  If it is practiced well, the body moves like a well oiled machine, each part moving on a series of ball bearings.  The Chan Si Gong gradually builds up power through coordination, linking all the body’s joints like a string of pearls.  It teaches you the Tai Chi principle of moving the body as one unit.  The Tai Chi classics state that jin starts in the feet and is controlled by the waist and expressed by the hands.  This explains the way that Tai Chi generates and releases power.  It sounds simple.  However, in order to achieve this, each joint has to be strong yet flexible, and be able to listen and work with all other parts of the body.  If one joint is weak or tense, the force will be neutralised and the ground force will not be released.  What is released will only be a fraction of that potential power."
-   Silk Reeling Gong: The Key to Improving Your Tai Chi Form.   By Brett Wagland. 

"Silk reeling (pinyin chánsīgōng, Wade-Giles ch'an² ssu¹ kung¹ 纏絲功), also called "Winding Silk Power" (chansijing) (纏絲勁), as well as "Foundational Training"(jibengong), refers to a set of neigong exercises frequently used by the Chen style, Wu style and some other styles of T'ai Chi Ch'uan. The name derives from the metaphorical principle of "reeling the silk from a silk worm's cocoon". In order to draw out the silk successfully the action must be smooth and consistent without jerking or changing direction sharply. Too fast, the silk breaks, too slow, it sticks to itself and becomes tangled. Hence, the silk reeling movements are continuous, cyclic patterns performed at constant speed with the "light touch" of drawing silk.  In common with all Qigong exercises, the patterns are performed in a concentrated, meditative state with an emphasis on relaxation. However, rather than being isolated exercises purely for health benefits, the focus is on strengthening and training the whole body coordination (nei jin) and grounded body alignment that is used in the Tai Chi form and pushing hands. Silk reeling is commonly used in Chen style as a warmup before commencing Tai Chi form practice, but its body mechanics are also a requirement of Chen Style Tai Chi throughout the forms. In other styles, silk reeling is only introduced to advanced levels. Many schools, especially those not associated with the orthodox Tai Chi families, don't train it at all."
-  Silk Reeling - Wikipedia

"Single movement exercises, known as Chansi Gong, which develop silk reeling energy. These are a series of simple movements which build on the postural alignment and qi circulation developed by standing post exercises. These qualities are now manifested while the body is in motion. The aim is to develop the basic strengths and coordinations of Taijiquan: such as, whole-body power, use of frame and abdomen to initiate movement and generate power, twining energy, the fundamental concepts of opening (kai: expansive power) and closing (he: contracting power)."
-   Chen Style 

    "Coiling power (Chan Jin) is all over the body. Putting it most simply, there is coiling inward (Li Chan) and coiling outward (Wai Chan), which both appear once (one) moves. There is one (kind of coiling) when left hand is in front and right hand is behind; (or when) right hand is in front and left hand is behind; this one closes (He) (the hands) with one conforming (Shun) (movement). There is also one (coiling) that closes the inside of the left (side of the body) and the back of the right (side of the body), and another which uses the through-the-back power (Fanbei Jin) and closes towards the back. All of them should be moved naturally according to the (specific) postures.  Once Qi of the hand moves to the back of the foot, then big toe simultaneously closes with the hand and only at this moment (one can) step firmly.  This power (Jin) comes from Heart (Xin), on the inside it enters bones, on the outside it reaches skin, it is one (power), not multiple (powers). Power is Qi that comes from Heart. If it is moved in central and right way, then it is Central Qi (Zhong Qi); when it is nourished, then it is Noble Spirit (Haoran zhi Qi).  At the back (the power of) the head propping up is (called) Propping-up Power (Ding Jin); large vertebra is the dividing line, below (this) dividing line is the back (Lь), the central bone is backbone (Ji), both kidneys are (called) Waist. Whether foot is Empty (Xu) or Solid (Shi) depends on hand, if hand is Empty then foot is also Empty, if hand is Solid then foot is solid too."

“When we begin our training, when we learn to perform the movements in the correct way, it has a stimulating effect on the spiral motion inside the body.  Performing the movements correctly, doing the outer circling and spiraling movements within the form, is something that develops gradually, something you learn step by step.  The space, the distance between the incorrect and correct execution of the movements, is what we call ‘temporary mistakes,’ mistakes that occur midway, obstacles so to speak.  These mistakes, these obstacles on the trail are part of the normal course of learning Taijiquan; they belong to it and are part of the way of learning the Gong, that is: the artistry.”

"Silk-Reeling Exercises (Chan Si Gong) - "Gong" in Chinese means work or skill or exercises (drills). Silk-reeling Exercises (SRE) in Taiji are a set of repetitive spiral movemnet exercises with emphasis on --- the ground connection, waist connection, knee alignment, kua sinking, opening and closing of joints and dantian rotation. These continuous spiral movement are the basic components, the foundational building blocks of Taijiquan. This series of spiral movement exercises are for the development of the basic strengths and coordination of Chen Taijiquan. These exercises will increase the mobility of body joints and relax the muscles and tendons of the practitioner. The spiral movements will open up and exercise the 18 major joints (in sequence from the head to the ankles) of the body, promote muscle relaxation and flexibility, and reduce physical tension and strain.  Many people misunderstand the nature of SRE. They believe that SRE are only a set of stretching exercises to stretch the bones, muscles and tendons of the practitioner. Silk-reeling exercises can be considered as stretching exercises which use the Taiji principles to help relax our bodies physically and mentally, but the reverse is not true.  SRE must be taught by a qualified instructor, who knows the theory of these exercises so that the essential quality of these exercises can be obtained. These exercises must be practiced correctly to prevent body injury."

"The Silk Reeling technique is an internal art of high degree. It is one of the fighting, power discharge skills and does not appear to have been communicated to Yang Luchan (if it was he does not seem to have taught it) and is therefore unique to the parent Chen style TaiChi.  These exercises exaggerate in the outer form the subtle internal movements that must be aquired within to make it work. Students who practice these exercises diligently and regularly everyday can expect to see initial weak and uncoordinated results within 6-9 months under correct guidance. The rest takes years.  This technique makes use of a combination of weight shifting in the legs and a corkscrew motion in the body that originates from the lower torso (dantian) ultimately radiating out to the arms in a number of different manners at will (in the experienced practicioner). Actually it is too subtle to learn from a video alone and even with a highly experienced teacher it requires significant instruction and inspection.  It takes years of continuous practice to develop, strengthen, control and explore the myriad martial applications of this skill and in fact even masters never stop learning and developing this technique. Chen Fake was very devoted to exploring this skill and created his "New Frame" while teaching in Bejing to deepen its use beyond that contained in the "Old Frame".  Its use is implicit in all movements of the Chen Routines and the beauty of this subtle, spiral twining of the central body is but a "side-effect" of what is primarily a powerful martial skill. This delicate twining only adds to the wonderful, liquid flowing grace of the outer form that we admire in TaiChi.  A seasoned practicioner can actually exercise this martial skill fully without visible expression in outer movements. Indeed this is the goal in continuous practice of both the Large and Small Frame Traditions mentioned above.  Once a Chen practicioner gains mature experience in use of the Silk-Reeling art one then attempts, over time, to make smaller and smaller outward use of the arms and their circular movements (which are in fact used as a "prop" to help the learner first feel then control its internal use). Hence the advice often heard in connection with learning of the Small Frame Routines - "turn your small circles into invisible circles."  In combat the Silk Reeling contains both Yin and Yang aspects. In Yin ("female") mode it can be used to dissipate and neutralise the force of an incoming opponent by "turning it into an empty place."  When Silk Reeling Skill is used in Yang ("male") mode the spiral movement "collects" muscle force from around the whole body by means of a sort of rising "shock wave" that rides on top of normal body movement. It is first dropped down from the dantian (diaphragm area) to the legs then "bounced" back up the body with additional energy added by untwining the torso as the "wave" rises. Finally this force is "discharged" in the extremities of the body (fist, elbow, shoulder) on contact with an opponent in a frightening pulse of concentrated momentum.  Often both Yin/Yang aspects are combined so that the force of an incoming opponent is "re-vectored." In other words the Silk-Reeling can be used to "rebound" the force of an incoming opponent back upon himself. The faster the attack the faster the rebound - much like objects thrown at a fast spinning top.  This Chan Si Gong (silk-reeling) successfully yokes stationary QiGong to the hard external martial arts - which seem almost opposite exercises. This powerful harmonising of opposites (which is what the words "TaiChi" originally meant) gives birth to something new - a powerful, "soft" internal martial art, a "moving QiGong", a TaiChi Chuan. Thus is Chan Si Gong a bridge between the stationary Zhan Zhuang exercises (a form of QiGong practised by TaiChi stylists) and the Old Frame One.  The Silk Reeling technique cannot be safely practised without the correct technique, profound relaxation of the body (in its execution), highly mobile joints and a long habit of correct body alignment. This is the purpose of the Silk-Reeling exercises in conjunction with Zhuan Zhang (Qigong Standing exercises) and Old Frame One. The Silk Reeling exercises also help turn the Old Frame One into a true "moving Qigong."

"Some of the most common silk reeling exercises are:

• Single Arm - Front Circle (zhengmian) (Left and Right Side)
• Double Arm - Front Circle
• Single Arm - Side Circle (cemian) (Left and Right Side)
• Double Arm - Side Circle
• Peng-Lu (Left and Right Side)
• Peng-Lu-Ji-An Reeling Silk (Left and Right Side)

Once these are learnt and understood footwork (Bu fa) is added including: side stepping, diagonal stepping, forwards and backwards stepping:

• Single arm side stepping - Front Circle (zhengmian) (Left and Right Side)
• Diagonal stepping (Shaung – Lu) (Left and Right Side)
• Alternating leg diagonal stepping
• Forward stepping (Shaung Bu)
• Backwards stepping (Tui Bu)
• Double Arm side stepping - Front Circle (Cloud Hands – Yun Shao)."

"In relation to the discussion on the subject topic, Silk Pulling and Silk Reeling, please allow me to offer the following:

1.    The Classics states "yun4 jing4 ru2 chou1 shr1." It also states, "fa1 jing4 ru2 fong4 jien4." Literally, it means "mobilizing the jing like pulling silk," and "discharging the jing like releasing an arrow."  To do it like pulling silk, one needs to be relaxing, soft, and sensitive, and be able to give up himself and follow his opponent.  Not only that the silk is not to be broken while being pulled (slow or fast), but also allowing no kinks or discontinuities to form during the process. "Discharging" part is just a natural byproduct of "yun4 jing4 ru2 chou1 shr1."  There is a Chinese saying, "When water comes, a channel forms."  It takes time to accumulate enough water to form a channel, and, likewise, it definitely takes time to become good!  So, be patient.  I don't know if it can be emphasized enough!

2.    The term, "tsan shr jing" (or, silk reeling jing), first appeared in Chen Xin's book of "Chen's Tai Chi Chuan". Some says that he invented the term, and I believe it.  The problem here is that he really was not a tai chi chuan exponent.  He was just doing "research" on Chen's tai chi chuan.  He incorporated principles of I-Ching, Five Elements, and Ba-Gua in the book, and in such a way that few, if any, tai chi chuan practitioners would, and would care, to understand.  How he got the courage to write such a tai chi chuan book, without the very knowledge of it is still a mystery to this day.  However, this "silk reeling jing" thing eventually serves as the life-saving element for the Chen's style people who were so desperately trying to justify their external-style-like "paw tui" as a tai chi chuan. Note that even in as late as the early years of this century, Chen's routines were not recognized as one of tai chi chuan; they were categorized under the list of external styles.

3.    The Chen's style's "silk reeling" has got nothing whatsoever to do with the above mentioned "silk pulling", which the Classics emphasizes. "Silk reeling jing", as practiced by the Chen's stylists, symbolizes the (spiral-like) advancement or retreat of motion from one point of the body to the other.  There is nothing wrong with it, in the context of being able to more efficiently develop the power. Some other external styles have it too.  Except, when it is manifested in the tai chi chuan routine in an explicit way, like they do, then, we have problem.  Because it is against the Classics.  The teaching in the Classics is reflected in the ever so profound words of "rooting at foot, develop in leg, control in waist, and, finally, expressed in fingers."  It is implicit, it is inwardly searching, and it is the tai chi way.  In my opinion, the tai chi chuan postures should not be formulated and put together based on outwardly, body-initiated movements.  Instead, it should be based on inwardly, chi- and shen-initiated, meditational movements.  Mere physical exercise, let alone body trembling, with no instilling of meditation, can hardly be qualified as Daoist tai chi chuan.

4.    What we should know from practicing the Cheng Man-ch'ing tai chi chuan is that, if done correctly, at certain level, all the external movements will become less important, and at that time, one really doesn't have to (visibly) turn the body (or limbs, for that matter), in order to transmit the jing.  All he would need is "relax, sink, and discharge", and the arrow will be shooting out like no one would believe it.  Senior students should have this kind of experience.

5.    Don't get fooled by the seemingly beautiful exhibition offered by other styles. As another Chinese saying has it, "experts look into the real stuff, while outsiders enjoy the excitement." Therefore, if I may say so, don't even contemplate practicing some such things as "silk reeling jing". Because, if they were good, we would have been taught thru the lineage. Besides, in my opinion, it most likely will not help your tai chi chuan; instead, it may hinder your progress in many different ways, not to be elaborated here."

-  Dr. Arnold Lee, Maryland Tai Chi Chuan Center, 1999, To the Cheng Man-ch'ing Tai Chi Chuan Brothers and Sisters

"On a more complex level, he said, "silk reeling energy is the application of the idea of silk reeling to obtain power and energy.  He compared the actual, physical activity of silk reeling technique of the human body to the action of a towel that is wrung to squeeze out the small of the back behind the navel the waist, back and shoulder right through the arms to the hands, and down through the hips to the knees and feet. The movement of everything goes together.  The spiraling of the waist creates spiraling of the shoulder, elbow and wrist as well as the hips, knees and ankles. The whole thing is called reeling silk. 

There are three basic principles of movement.  The first is spiraling.  The second is anterior and posterior extension.  The third is putting together the spiral with anterior and posterior flexion of the spine.  While this complex change is taking place, the dantian, the energy center in the abdomen a few inches below the navel, is the center.  As the basic method of practice, the function of silk reeling energy is to unify the body and connect the energy throughout the body with the dantian so that it can reinforce movements of all parts of the body.  Training in T'ai Chi Ch'uan, regard less of style, has as its function the connection of silk reeling energy throughout the body and making it strong and fluid and accessible."
-  Grand Master Chen Xiaowang, Silk Reeling Energy Skills

"Chen style Taijiquan is complex: weight shifts, whirling arms, stepping, dantian rotation, sinking the hips, weight in the feet, relaxing the chest… all the while trying to remember the next move! Fortunately, there is hope. Each move can be broken down into principle components and practiced individually and re-assembled during form practice. Grandmaster Chen Xiaowang is credited with developing the simple exercises known as Silk Reeling (缠丝功 chánsīgōng). David Gaffney and Davidine Sim say it very well in their book “The Essence of Taijiquan" p. 168:

“The silk reeling exercises comprise of individual movements, the mechanics of which make clear the basis for one or more movements contained within the form. They provide a pathway of utilising jin (劲) or trained power.”

The name, Silk Reeling, comes from “the old days” when people would pull silk from the cocoon by hand.  Apparently, this process required a very slow and consistent pull to coax the silk thread off the cocoon.  This image is so foreign that it is hard to grasp what is being implied.  The first silk reeling exercise is usually referred to as “Front Silk Reeling” (正面缠丝功 zhèngmiàn chánsīgōng) or sometimes just “the first single hand silk reeling”.  Unfortunately, no poetic names as in the forms such as “crane spreads wings” or “snake creeps up the mountain”… maybe I’ll call it “the bat flies at midnight”!"
-  Travis DePuy, Silk Reeling Explained

"There are various qigongs which emphasize the style of movement fundamental to the Neijia: the Yang style Tai-Chi qigong, the Xingyi neigongs, the Chen style" Reeling Silk" qigongs, etc.  All of these qigongs and all of the internal styles are quite capable of producing "internal strength."  Because of the sophistication of the Chen style reeling silk exercises and because they are becoming popularly known, though, let's focus on some suggested criteria to keep in mind while practicing a set of reeling silk exercises (Chan Si Gong). These suggestions are meant for people who already do reeling silk exercises; you cannot learn to do them from words.

1. Concentrate on keeping a complete and relaxed "peng path" at all times to the area which is being moved and move the area by "pushing" it with "peng" and "pulling" it with contraction/closing/down-weighting vectors.

2. Always pretend that there is someone holding their hand on the part being moved; someone who is constantly monitoring the completeness of the ground path (peng) and the relaxed nature of the transmitted power.

3. Use large movements with the whole body to start with. Gradually, over a period of months, make the movements (envisioning the same "monitoring") smaller and smaller. Because the "peng path" goes through and is manipulated by the "Dantian" area, it will get a more intensive workout as the external motions get smaller.

4. Do as many of the exercises as possible with the knees bent somewhat (do not go so low that the thigh goes below a 45-degree angle, though). This will greatly strengthen the leg and hip muscles.

5. Do the exercises from the head down to the toes.

6. One of the main goals is to train "peng" power, down (closing) power, and body inertia to the arms, so that the arms are "transmitters" of this power. Keeping very relaxed and concentrating on keeping these powers in the arms will bring them there. Local strength in the arms and shoulders will deny progress.

6. One of the main goals is to train "peng" power, down (closing) power, and body inertia to the arms, so that the arms are "transmitters" of this power. Keeping very relaxed and concentrating on keeping these powers in the arms will bring them there. Local strength in the arms and shoulders will deny progress.

7. There are really 6 directions of power: push out (peng), pull in (peng from behind and contraction), lift up (peng vector), weight down (closing and weight vector), waist-turn forward (peng combined with opening), and waist-turn backward (peng combined with closing). All movements are variants of these 6 directions. These 6 directions are really only variants of peng and closing.

8. In all movements downward or backward/downward, there should be a very slight storage in the lower back.

9. The exhaled breath goes with the imagined application of power, the inhale goes with the storage.

10. The peng should be felt at all times in the cycle of a movement ("No gaps, no deficiencies")."
