In recent years,archaeological work at the Erlitou site in Yanshi,Henan Province has revealed a layout in the shape of the Chinese character"井"(jing),which,when analyzed from the perspective of the traditional Chinese spatial-temporal system,represents the concept of the"jiugong"(nine zones).The knowledge system of the jiugong spatial arrangement directly influenced the planning of traditional political geography and the establishment of governance strategies,as seen in the stories of Yu the Great dividing the Nine Provinces and the Nine Categories of the Flood Control Measures.In light of this context,understanding the Erlitou site suggests that its layout is believed to directly inherit the legacy of Yu the Great,the legendary founder of the Xia Dynasty,who divided the Nine Provinces and followed the principles of the Flood Control Measures.This further supports the notion that the Erlitou site was the late Xia Dynasty royal court established by the descendants of Yu the Great.
