BRUSH

Brush (刷子) β€” a scissor-class (ε‰ͺη±») move where one foot traces an S-curve while the other traces a Z-line through the cones.

Trajectory​

  • S foot: weaves around cones in an S-curve
  • Z foot: moves in a straight zigzag line
  • Combined: creates a scissor-like crossing pattern

Step-by-step (forward brush)​

  1. Start: feet parallel outer-eight, body facing away from cone line
  2. Do half a back scissors to cross past the cone β€” maintain crossed outer-eight between two cones
  3. Slight squat at knees β†’ use waist/hip force system β†’ rotate ankles ~45-90 degrees
  4. Lower body follows upper body's rotation (involves body turning)
  5. Open the crossed legs to pass the next cone β€” feet open shoulder-width, landing on both sides of the cone
  6. End position = starting position (outer-eight parallel) β†’ can repeat infinitely

Key points​

  • Waist/hip initiation, not ankle-driven β€” the hip force system (θ…°θƒ―ε‘εŠ›δ½“η³») powers the crossing
  • Opening width = shoulder width, no wider
  • The body turn in step 4 is what distinguishes brush from a simple scissors

Variants​

  • Forward brush and reverse brush β€” same principle, different facing direction
  • 点规 Brush: five-wheel (toe) state throughout β€” the most commonly seen form
  • Front brush is harder β€” requires significant ligament flexibility

Extension potential​

Brush is highly extensible via movement_extension_method:

  • Element addition (add pivot β†’ pivot brush)
  • Element substitution
  • Deconstruction and recombination
