Writing Balance Rule: The left component (dog radical 犭) should be narrower and slightly compressed, leaving ample space for the complex right component (蜀) to maintain structural harmony.
Simplification Logic: The traditional form 獨 uses 蜀 on the right. In the simplified form 独, the right component is retained with standard script stroke adjustments while the left dog radical is simplified to 犭.
