Writing Balance Rule: The left component (尸) should be slightly narrower to leave ample room for the right component (句), maintaining a balanced vertical center of gravity.
Simplification Logic: The traditional character 跼 uses the foot radical (足) on the left, whereas the modern simplified form 局 replaces it with the corpse/canopy radical (尸), transforming it into a compact phono-semantic character.

5. History
Liushu category: Phono-semantic (形声)
Origin: Originally written as 跼 with 足 (foot) and 句 (bent), depicting a person walking with a bent leg or in a cramped posture. Over time, the form was simplified to 局, absorbing multiple meanings related to confinement, structure, and offices.
Semantic Evolution: From the physical sensation of being cramped or bent over, it expanded to mean confined spaces, then to administrative bureaus enclosed within walls, and eventually abstract setups or games (棋局).
The shift from 跼 to 局 standardizes a common phonetic borrowing in early Chinese printing.
