The interpretation of the word fence can go back to its origin. In ancient times, the fence was mainly surrounded by wooden sticks or fences. At first, it was an obstacle for raising various livestock, and later it gradually became a kind of enclosure. It is said that fences in the true sense originated in Europe and mainly appeared around noble buildings such as castles, palaces, and manors, and the materials were mainly made of iron. Later, as the times changed, it was gradually widely used by the general public.
