Stone railings are a particularly common component of traditional Chinese architecture, used around corridors, bridge sides, flower beds, gardens, pavilions, terraces, and more, to enclose and prevent danger.The Song Dynasty referred to it as "gou lan," commonly used on platforms with a Sumeru-style base, though it was also used on regular platforms. Stone carved railings typically consist of three parts: the pier, the rail, and the base. The pier is divided into two parts: the pillar body and the pillar head.。
