The railings in China have a long history of development. The old railings in ancient times were made up of several wooden poles, similar to the fences used in rural areas today. From the railings of the Zhou Dynasty, we can see the grid as a cross. The slats, that is to say the railings of this period have already had certain aesthetic functions. In the Han Dynasty, railings have appeared in various forms such as straight squats, lying squats, and oblique squares. The straight rails, reclining and hook-shaped railings are popular in the Wei, Jin and Southern and Northern Dynasties. These railings can be found in the murals of Yungang Grottoes and Dunhuang Grottoes. The characteristics of the railings during the Yuan, Ming and Qing Dynasties were that the wooden railings were relatively slender, while the stone railings gradually separated from the shape of the wooden railings and tend to be heavy. After the end of the Qing Dynasty, due to the influence of Western aesthetics, the railings attached importance to classical proportions, scales and decorations. With the advancement of technology and the improvement of life and culture, modern railings are more diverse in materials and shapes. The imitation stone railing is one of them. It is popular with people for its beautiful appearance, close to nature, low price and green environmental protection.
