Shili 试力

Why this stage is called the key

Zhan Zhuang builds whole-body force in near-motionless standing. Shili asks whether that force survives movement. Yao Chengguang puts the relationship in a sentence often quoted within the lineage:

“Zhan Zhuang is the foundation, Shili is the decisive method.”

Shili is thus the third stage of the training guide, but not merely the next exercise: it is the transition from static to dynamic — the point at which it becomes clear whether the standing produced something load-bearing or merely a posture.

The counter-force principle

A single instruction holds all Shili together: when moving forward you feel the backward force; when moving back, the forward force. The force opposes the movement. This is precisely what keeps the tension built in standing alive while the body moves — it is not set down in order to move, but carried along.

The mental image behind it is the same in all the basic exercises: water, or a viscous resistance. Pushing a board across the surface of water, scooping water, opening and closing against pressure. Alongside it the instruction 用意志，不是强力 — with intent, not with brute strength (Yi).

How the exercises are ordered

The Shili do not fit into a single list. Two axes cross:

• By stance and stage: three Pingbu Shili in the parallel stance as an entry point, ten Shili in the fixed fighting stance Dingba Bu, thirteen Zoubu Shili combined with stepping (tied to Mocabu).
• By type of movement: arm-led pushing and opening Shili, body-led Shenfa Shili, chopping Shili, hooking Shili.

Cutting across both is the degree of combination: single Shili versus freely combined ones (Zonghe Shili). Yao Chengguang's didactic progression sets out four forms — fixed stance, mixed fixed stance, with stepping, mixed with stepping. The last is the most direct preparation for fighting.

The three basic exercises

The entry point is three exercises in the parallel stance: Pingtui Shili (平推试力, pushing a wooden board back and forth on water), Boshui Shili (拨水试力, playing with the water) and Kaihe Shili (开合试力, opening and closing the arms). All share the same quality: very slow, continuous, without interruption. The larger sets build on them.

Where it leads

Shili trains three things at once: holding Hun Yuan Li together in movement, perceiving the finest nuances of force, and adapting spontaneously. This prepares for Tuishou and Sanshou — and without Shili, Fa Li cannot be learned. The guiding image: “the testing of force is the source of true force.”
