Writing Balance Rule: The left component (子) should be slightly narrower and compressed to make room for the right component (系/纟). Keep horizontal strokes parallel and balanced.
Simplification Logic: The traditional form 孫 uses the full 糸 component on the right, while the simplified form 孙 replaces it with the simplified radical 纟.
