rural area
閭 centers on a rural area or village, specifically the gate or entrance to a small community, evoking a sense of a quiet, countryside settlement.
閭 combines 門 (gate) with 吕, which likely represents a pair of mouths or a spine-like shape, possibly suggesting the gate of a village where people gather. The exact historical development is uncertain.
Picture a large village gate (門) with two small windows or mouths (吕) above it, like the entrance to a quiet rural area where people chat by the gate.
For リョ, imagine a rural village gate where a traveler named Ryo (リョ) always stops to rest. Ryo -> リョ, and the gate marks the entrance to the countryside.
