Lie (挒) — often translated as "Split" — is one of the Four Corner Energies (Si Yu). It represents a type of spiral or rotational force that separates or tears energy in two directions.

• Lie means to split apart, like tearing or wrenching something in two opposing directions.

• It involves opposing forces applied simultaneously — typically in a diagonal or spiral pattern.

• The goal is to unravel the opponent’s structure by creating internal torque or twisting that breaks their balance and alignment.

Energetic Concept:

Lie Jin (splitting energy) is often performed by using one part of the body to move one way, and another part in the opposite direction — for example, one hand pushes forward while the other pulls back.

This creates a rending or spiraling force that is difficult to resist because it doesn’t come from a single direction.

It’s an expansive and explosive energy that disrupts and controls.

Application:

Used to throw, lock, or take down an opponent by twisting or splitting their axis.

A common example is when one hand grabs or leads one side of the opponent's body, and the other hand or elbow controls or pushes in the opposite direction — like wringing a towel.

It is also used in joint manipulation, sweeps, or throws, where the opponent’s limbs or torso are rotated against themselves.
