Pebble is a kind of pure natural stone, which is taken from the gravel mountain produced by the uplift of the ancient river bed after the crustal movement thousands of years ago. It has experienced constant extrusion and friction in the process of mountain torrents and running water transportation.
In the course of tens of thousands of years' vicissitudes, they experienced the rushing movement of waves and currents, lost their irregular edges and corners by the collision and friction of gravel, and were buried deep underground with sediment for millions of years.

The main producing areas of rain flower stones in China come from Nanjing and Jiangsu, and the middle and lower reaches of the Yangtze River are rich in resources, mostly in sedimentary form.
In addition, there are abundant pebble resources in other areas, including Shandong and Liaoning in the north and Guizhou, Chongqing and Guangxi in the south. Pebble resources have their own characteristics and are rich in species.
Among them, due to historical reasons, the pebble resources in Guizhou and Guangxi are well preserved and rich in species.
There are many large pebbles in southwest China, which are large in size and strange in shape, and are especially suitable as geomantic stones or cultural stones in landmark buildings.
