Writing Balance Rule: The left side (弓 bow) is compact and vertically elongated, while the right side (单 single/simple) is wider and balanced with horizontal strokes.
Simplification Logic: Simplified from 彈 by streamlining the right-hand component 単, reducing complex strokes while preserving the bow radical.
