Lu" (掤) is one of the fundamental energy principles or Jin (劲) — it typically translates as "Roll Back" or "Redirecting" energy

Essence of Lu:

• Lu is about yielding and redirecting the opponent’s force.

• It uses a circular, backward, and sideways motion to neutralize the opponent's attack, drawing their energy into emptiness.

• Instead of resisting directly, the practitioner “melts” away the incoming force and then redirects it.

Application:

If someone pushes you, instead of blocking, you connect and rotate your center and arms to let the force pass, leading the opponent into a vulnerable position.

After Lu, you can follow up with Ji (Press) or Cai (Pluck) for a counter.
