Located on a hilly terrace west of the Taihang Mountains and flanked by the Songxi River, the site was excavated in 2024 and 2025 by the Shanxi Provincial Institute of Archaeology and partner institutions, leading to the discovery of 18 tombs, including six Xia Dynasty burial sites and 12 Warring States Period (475BC-221BC) graves. 
"These are the highest-ranking Xia aristocratic tombs discovered so far, indicating that this location was a regional center," the institute said.
The Xia Dynasty is traditionally regarded as China's first hereditary dynasty, though contemporaneous written records are lacking.
The well-organized Xia tombs, concentrated in the western part of the cemetery, feature uniform east-west oriented vertical earthen pits. Researchers recovered nearly 40 sets of artifacts with distinctive local cultural characteristics, including pottery, lacquerware and turquoise ornaments. 
Extended regional surveys across the Songxi River valley yielded more than 10 Xia and Shang period sites. Test excavations at nearby relic sites unearthed pottery fragments, stone tools, bronze knives, as well as tin-bronze ingots and smelting residue, providing solid evidence of early metal mining and craftsmanship. 
Local copper-iron symbiotic ore deposits confirm exploitation of these resources during the Xia and Shang eras, while typical cultural artifacts found in adjacent counties reveal widespread regional cultural exchange.
Multidisciplinary analyses further decoded the civilization's features. Ancient human remains belong primarily to the ancient population of the Central Plains with minor Mongolian Plateau ­genetic traits, forming a stable patrilineal clan. The community relied on millet farming and maintained long-distance resource trade networks. 
Artifact provenance tests trace scallop shell ornaments to the Bohai Sea, cinnabar to Hunan-Guizhou ore belts, turquoise to the eastern Qinling Mountains area, and coffin timber to local Taihang pine trees. Such diverse materials reflect close interaction among the Taihang foothills, the press release noted.
Lab restoration unveiled refined ritual relics, including a dragon-patterned lacquer cylinder with red and black stripes and an intact lacquer gu vessel (a type of wine vessel). Turquoise plaques from the site match specimens from the Erlitou site, a core Xia cultural relic, proving ­cross-regional cultural interaction. Radiocarbon dating places the site's active period between 1880BC and 1450BC, aligning with the late Xia Dynasty.
Scholars confirmed the findings have helped reshape academic understanding of Xia-Shang civilizations and reconstruct multi-level settlement patterns on the western Taihang foothills, while offering new insights into social complexity and civilization development in early China.

B | 公司也在积极建设新产能，做好光芯片、电芯片、PCB等核心物料的准备，为27年更大规模上量做好准备。　　此外，公告还称，物料供给目前比较紧张，主要由于下游需求增长太快，上游扩产速度偏慢。部分物料确实出现涨价，但公司供应量较大的产品涨价幅度并不大，主要是因为公司已锁定较强合约，订单量也较大，拿到的价格较有优势。在后续客户交付上，公司的产品价格降幅相对理性，并非市场传言的剧烈下降。整体而言，公司通过技术手段（包括硅光比例和良率提升）、27年新产品放量等方式，均有利于把控成本，进一步提高整体毛利率水平。（文章来源：财联社）。
