Writing Balance Rule: The left side (彳) is narrower and taller, while the right side (复) is wider and spans the remaining space with balanced horizontal segments.

Semantic Clue (形旁): 彳 (indicates walking, stepping, or going back and forth)

Liushu category: Phono-semantic (形声)

Origin: Originally depicted walking back and forth along a path (represented by 彳 and steps), capturing the concept of returning.

Semantic Evolution: From physical walking and returning to a place, the meaning expanded abstractly to repeating actions, restoring previous states, and replying to communications.
