Writing Balance Rule: The left side (character component 釒/钅) is compressed to take up about one-third of the width, while the right side (臷) claims the remaining two-thirds to keep the overall character balanced.
Simplification Logic: The traditional radical 釒 (metal) is simplified to 钅 on the left side, and the complex right component is streamlined.
