On Yu the Great dividing the Nine Provinces and the Nine Categories of the Flood Control Measures 

Abstract：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.

An archaeological investigation into the disaster at the Lajia site 

Abstract：The Lajia site is a large settlement site of the Qijia culture in the upper reaches of the Yellow River. Through archaeological excavations over the years, large disaster remains of the Qijia culture period were found, including destroyed and severely deformed house sites, a large number of human bone remains of unnatural death inside and outside the house sites, ground cracks, red gum mud accumulation, and ash sand accumulation. Taking the distribution range, distribution characteristics, interrelationships, and time sequences of these catastrophic remains as the starting point, we systematically analyze the ancient catastrophic events that occurred at the Lajia site from an archaeological perspective by combining the results of previous research. The study shows that between 1980 and 1900 B.C., a large mudslide from the northern gorge destroyed the southeastern part of the Lajia site and killed part of the population living in the area, followed by a major earthquake that affected the entire Lajia site, in which the Lajia village was completely destroyed and the surviving Qi ancestors fled. Within a year or two after that, a great flood of the Yellow River swept through the lower elevation area of the Guan Ting basin, including the La family site, and thus, the La family site was completely buried.

The New Trend in the Development of Jade Culture around 4300 Years Ago 

Abstract：The time around 4300 years ago marks a crucial archaeological and cultural development milestone, representing a key stage in the transition from ancient states to states. During this period, various regions such as Haidai, southern Shanxi, northern Shaanxi, Gansu-Qinghai, and the middle reaches of the Yangtze River witnessed the development of multiple jade-using centers, represented by cultures such as Shandong Longshan, Taosi, Shimao, Qijia, and later Shijiahe. This period saw the emergence of the second peak in the development of Neolithic jade culture, showcasing the simultaneous coexistence and mutual influence of various jade cultures. Multiple centers existed in different regions and jade cultures exhibited new characteristics such as a North-South pattern. Jade artifacts, as important indicators of cultural progress, reveal new trends in the development focus, ritual systems, and role transitions during this phase. These trends reflect changes in societal complexity and cultural integration, marking a significant shift in ideological aspects of civilization.

On the casting technique of the bronze lei at Yinxu 

Abstract：Building upon previous research, this author comprehensively investigates the casting techniques of late Shang Dynasty bronze jue vessels, including the casting patterns, repair casting, secondary pouring, dent, spacers, and pouring openings identified from the bronze jue vessels unearthed from Yinxu. Additionally, information provided by physical artifacts such as casting patterns, molds, and cores discovered at bronze casting sites at Yinxu is examined. The study covers various aspects of the casting process, including the division of casting patterns, the production methods of the jue handles and inner rings, the assembly of casting patterns and cores, as well as issues related to spacers and pouring openings.

A chronological study of the proto-porcelain wares of the Spring and Autumn period from the Jiangnan area 

Abstract：Proto-porcelain is the primitive form of Chinese porcelain. The peak of proto-porcelain production occurred during the Spring and Autumn period. There was a transitional period around the time of Spring and Autumn during which the type and the technology gradually developed from Western Zhou Dynasty and contributed to the prosperity of Warring States Period. Based on a comprehensive systematic typological study on the proto-porcelain in the Spring and Autumn period of the Jiangnan region, this paper refined the chronology into three phases and six section. In the Early Spring and Autumn period, the types of artifacts are rich, complex and include diverse decorations. From the Middle Spring and Autumn period, the type and decoration tend to be simplified. In the Late Spring and Autumn period, plain cup bowls became dominant. However, since the second stage, the quality of the glaze has been significantly improved, which laid a solid technical foundation for the development of the proto-porcelain in the Warring States period.
