"Railway", the original "dry" originally refers to the coverings woven with wood, and later developed railings made of different materials such as stone, brick, and glass.
The railings were set up as early as the Zhou Dynasty, which can be seen in the Ming Dynasty ornamentation that remained in the Zhou Dynasty. In the Han Dynasty, the use of railings has become more common. At the same time, the railings have also appeared in the rods, Huaban, Wangzhu, and mantle. During the Southern and Northern Dynasties, the railings were basically shaped by the railings seen in later generations. Later, after continuous development and enrichment, the railings in the Ming and Qing Dynasties became more and more complicated in decoration.
