Pebbles get their name from their resemblance to a goose egg. As a kind of stone stone, pebbles are taken from the sand and stone mountains produced by the uplift of the ancient river bed after the crustal movement tens of thousands of years ago, and have experienced the continuous extrusion and friction in the process of mountain flood impact and water transport. In the process of millions of years of vicissitudes of life, the pebbles have been subjected to the movement of waves and water, and have lost their irregular edges and corners by the collision and friction of gravel, and have been buried deep in the ground for many years.Cobblestone is widely used in public buildings, villas, courtyard buildings, paving (cobblestone roads in parks), park rockeries, bonsai filling materials, garden art and other superstructures. It not only carries forward the ancient culture of the East, but also reflects the classical, elegant and back-to-nature artistic style of the West.
