Now our perspectives are starting to diverge, but thatās a good thing, it makes for an interesting discussion š
From my perspective, Peng is absolutely foundational to both applying and reversing qinna. Peng is the internal inflation that gives structural integrity: itās what makes your own āhoseā difficult to kink, and what allows you to effectively kink someone elseās. Without that internal fullness and continuity, qinna tends to become local, muscular, and easily countered.
Peng is also inseparable from Ting Jin. Without Ting Jin, you donāt reliably perceive the opponentās internal state, direction, or vulnerability, and without that perception, applying qinna becomes guesswork rather than skill. In that sense, Peng isnāt just supportive of qinna, itās what makes refined qinna possible at all.
That said, I completely agree that form alone does not produce functional skill. Partner work is essential. But in traditional internal training, partner work is introduced after the body method has been sufficiently forged. This sequencing is intentional. The uniqueness of internal martial arts lies precisely here: they prioritize the development of internal body capacity first, and only later does it become functional skill, when you learn to express it through specific applications.
This difference in emphasis is also reflected in Chen Fakeās oft-quoted view that roughly 90% of training should be done alone, with only about 10% in partner work. That ratio is almost the inverse of most external or modern martial arts, where partner drilling dominates. The reason for this inversion isnāt philosophical, itās practical: in internal arts, the primary task is forging the body method itself, which must be developed independently before it can function reliably under contact.
So when I say the body method (Shen Fa) is the method, thatās not philosophical, itās literal. Peng isnāt a concept you apply on top of technique; itās a trained internal condition that techniques emerge from and are constrained by. Without it, you can still learn qinna, sweeps, counters, but they will be external, conditional, and limited.
I also want to push back a bit on the idea that āactual training methods are kept private", while talking about principles reveals nothing. I think that framing slightly misses whatās really going on.
The real dividing line isnāt principles vs. methods, itās what can actually be transmitted without a teacher.
You can talk about Peng endlessly, but talking about Peng does not give someone Peng. Likewise, you can talk about qinna, show qinna on video, or even break it down step by step, and none of that grants the ability to apply it internally. Without the internal body method, those methods are functionally hollow.
In fact, Iād argue the opposite of what you seem to be suggesting:
Applications are far easier to recover than the internal body method. Two bodies interacting can rediscover joint locks, sweeps, counters, and punishments. That kind of knowledge is mechanically available. But Peng, the internal inflation, continuity, and load-bearing integrity of the body, is far more elusive. Itās not obvious, not visible, and not intuitive. Once that is lost, itās extremely hard to reconstruct.
Thatās why, historically, the āsecretā was never really a specific application. The secret was the body method. Once Peng is genuinely present, applications stop being mysterious, you can feel where to apply force, where structure breaks, where control emerges. Without it, no amount of application knowledge closes the gap.
So yes, talking reveals little, but thatās true of both principles and applications. What actually matters is whether the internal condition of the body is being cultivated. And thatās precisely the thing that cannot be learned from words, videos, or public discussion, and the thing most easily lost if it isnāt preserved carefully.
I think we may actually agree more than it first appears. There is far too much pontificating about principles in the abstract. Where I differ is that I donāt see this as an error of emphasis so much as an error of intellectualization, trying to think oneās way into something that can only be embodied. Ultimately, whether weāre talking about principles, methods, or applications, the real issue is the same: the vast majority of people simply donāt have the principles in their bodies.
