容róng

The simplified 容 keeps the roof (宀) and the interior shape that once represented a vessel or something being held, now reduced to a compact arrangement of strokes. In modern usage, the character extends to mean appearance, facial expression, and the capacity to hold or accept — all rooted in that original sense of containing something within a space. The simplification has stripped away detail, but the roof remains, suggesting that what lies beneath is still sheltered, still contained within defined boundaries. This is the character for "to contain" made efficient for daily use in a world of fast writing and mass printing.
