Functional characteristics of stone railings

Safety Protection: Physical barriers prevent pedestrian falls and vehicle overstepping of boundaries; municipal bridge railings can significantly reduce fall accidents.

Spatial Delineation: In garden architecture, railings divide areas without completely blocking views, maintaining spatial openness.

Cultural Carrier: Railing carvings encompass auspicious patterns (such as cloud patterns), regional cultural symbols (such as water town motifs), and narrative reliefs.

Stone railings were called "langan" or "goulan" in ancient China, with rudimentary structures appearing as early as the Zhou Dynasty. The Han Dynasty saw the development of horizontal lattice railings, and the hook-plate style of goulan emerged during the Six Dynasties period.
