In the Pearl River Delta region, felsic rocks are not widely distributed. Xiqiao Mountain has become an important and largest prehistoric stone factory in this region because its mountain is the best raw material for making stone tools. A large number of stone tools were exported as production tools, which played a positive role in promoting the development of productive forces at that time and led the transformation of prehistoric society from hunting and gathering economy to agriculture and industry.
In addition, Xiqiao Mountain culture is also the birthplace of Foshan's local civilization. These findings provide evidence that primitive ancestors thrived in the Pearl River Basin, indicating that Xiqiao Mountain is an important source of civilization in the Pearl River Delta region.
Therefore, Xiqiao Mountain culture is regarded as a beacon of the Pearl River civilization, illuminating the road of civilization development in the Pearl River Delta region.
