5. History
Liushu category: Phono-semantic (形声)
Origin: Originally formed to describe the outer lands where city territories meet the wilderness. It combines the 'mound/earth' radical (⻏) with the phonetic '交' (crossing/intersecting), depicting the point where civilization crosses over into open countryside.
Semantic Evolution: From ancient times denoting the borderlands outside city walls, it naturally evolved to mean modern 'suburbs' and 'outskirts'.
In ancient Chinese urban planning, the area immediately outside the capital walls was strictly categorized for ritual altars and agricultural outposts.
