Abstract Coin-minting models and molds can be classified into grand master patterns, master patterns, and casting molds, based on function. The archaeological data available at present show that the bronze coin molds are mainly master patterns and casting molds. This paper makes an as complete as possible collection of archaeologically unearthed bronze molds from the Warring States period to the Qin-Han dynasty, and then classifies them based on coin-minting technology and their functions and forms. After that, the ways to make the molds and to use them to mint coins, as well as the development procedure from vertical mold assembly technology to stack-casting technology are observed. Finally, the social background of the evolution of the coin-minting technology in this period is discussed.

Abstract After the downfall of the Tang dynasty, the Khitan-Liao empire, the Five Dynasties, and Northern Song dynasty formed the second “northern and southern dynasties” confrontation in the history of China. Also in this period, two systems appeared in the capital city planning: the “Shangjing norm” of the Liao dynasty characterized by the 日-shaped plan view and the “Dongjing mode” of the Northern Song dynasty characterized by the 回-shaped plan view. The “Shangjing norm” is the materialization of the political system of “ruling by the customs of the peoples being ruled” applied by the nomadic rulers from the northern steppes when they were managing the empire with the Han people as the majority. This seemingly reflected the ethnic discrimination of the nomadic ruling class at the beginning of the establishment of their empire. The capital designing ideas of the Jin, Yuan, and Qing dynasties were all following this norm at the beginnings of their rules. “Dongjing mode” of the Northern Song dynasty is the materialization of the “imperial sovereignty” idea emphasized by the empires founded by the Han rulers, which seems reflecting the bureaucrat system with the centralization as the characteristics. The designs of the Liao Zhongjing (Central Capital) and the Jin Zhongdu were both simulations of that of Dongjing, which showed the trends of ethnic convergence and unification. Moreover, Dadu of the Yuan dynasty and Beijing of the Ming and Qing dynasties were the symbols of the formation of the unified multiethnic empire of China.

In 2014 through 2018, Sichuan Provincial Institute of Cultural Relics and Archaeology and History Museum of Quxian County conducted a systematic archaeological survey, detection, and excavation to the Chengba site in Quxian County. The excavation uncovered 4,000sq m in total, from which 444 various features were recovered and over 1,000 artifacts were unearthed. The functional zoning of this site has been roughly made clear; the excavations of the western gate and important building foundations of the Guojiatai city site are important archaeological discoveries of the city sites of the Han through Western Jin dynasties, and at the checkpoint site on the waterway of this period was uncovered for the first time in China. The large amounts of bamboo slips and wooden tablets unearthed in the excavation provided important materials for the explorations on the management of the central government of the Han and Jin empires to the administrative areas of commandery and district levels and the social lives of the local people at that time.

Abstract The production and use of bronzes had significant influences on the social developments even the formation of the early states. However, in different areas, the bronzes played different roles. By observing the different characteristics of the bronzes in the Central Plains, the Ganjiang River basin, the Xiangjiang River basin, and the Chengdu Plains, various developments of societies can be revealed. The case studies of these areas can further explain the complex relationships between the bronzes and their societies, as well as the diversity of the patterns of the developments of the ancient societies.

In April and May 2011, Qingdao Municipal Institute of Cultural Heritage Conservation and Archaeology and Huangdao District Museum excavated the Tushantun Cemetery located in Huangdao District, Qingdao City. The excavation cleared three mounds and recovered seven tombs beneath them. Of these seven tombs, M6 and M8 are vertical shaft stone pit tombs with brick-timber coffin chambers and ramp passages, the burial receptacles of which are nested double-coffin and double-coffin chamber, and the grave goods unearthed from which include bronzes, jades, lacquered wares, pottery and porcelain wares and implements made of bone and horn (turtle scute). The types and styles of the tombs and grave goods all show that the dates of these two tombs are the late Western Han to the early Eastern Han Dynasty. The excavation of these tombs provided important physical materials for the studies on the burial system, geography and material culture in the coastal area of southeastern Shandong during the Han Dynasty.

The eighth season of excavation at the Jiahu Site in the autumn of 2013 uncovered eight house foundations, 25 ash pits and 97 burials, along with hundreds of artifacts made of pottery, stone, bone and ivory. One of the most intriguing findings was the burial of two adult males underneath the living floor of a house foundation 2013F5 belonging to Phase I. They yielded rich grave goods that included bone flutes, engraved ivory plaque, a set of turtle shells, and other high-ranking artifacts. They are, to date, the first ever in-house burials found in Chinese archaeology. In addition, the other burials also yielded large amount of turquoise ornaments and exquisitely engraved ivory plaques. These findings are significant to the study of the prehistoric funeral practice and social differentiation during the early and middle Neolithic Age of China.

In September through November 2015, Liaoning Provincial Institute of Cultural Relics and Archaeology and other institutions excavated Yelü Hongli’s tomb of the Liao Dynasty. This was a large-scale brick-chamber tomb consisting of the passage, ventilation shafts, entrance, corridor and tomb chamber; albeit having been looted in early years, many grave goods including silver wares, bronzes, iron objects, porcelains, wooden objects, jades, stone implements were unearthed, as well as architectural components and stone epitaph, and wooden coffin and bier were also preserved. This tomb located in Han Derang’s family cemetery, which was a part of the attendant burials of the Xianling and Qianling Mausoleums of the Liao Dynasty, was a tomb with exact date and yielding rich artifacts, and this was rare in the elite burials of the late Liao Dynasty, so it is significantly meaningful for the study on the burial system of the Liao Dynasty.
