There are similar railings on the ceremonial seat of the Zhou Dynasty. In the Han Dynasty, the horizontal lattice railings were the most common. In the Six Dynasties, hooks and hooks were prevalent. The pillars at the corners of the railings or the ones made by looking for the rod and twisting can be seen in the Yungang Grottoes and Dunhuang murals. The wooden railings in the Yuan, Ming and Qing Dynasties were relatively slender, while the stone railings gradually separated from the shape of the wooden railings and tended to be heavy. After the late Qing Dynasty, Western classical proportions, scales and decorative railings entered China. Modern railings are more diverse in materials and shapes.
