Core Viewpoint - The archaeological discovery at the Yong'an site in Shaanxi Province is significant for understanding the Yangshao culture and early social structures in the region, with the site being recognized as one of the six major archaeological finds of 2025 [1][4]. Group 1: Archaeological Findings - The Yong'an site has revealed a rich cultural connotation, with a total of 151 relics from the Yangshao period, including 14 house sites and 134 ash pits [1]. - The excavation uncovered 14 well-preserved semi-subterranean house sites, providing a model for studying settlement family structures [3]. - The ash pits exhibited a regular shape, with a significant number of bag-shaped pits containing a variety of artifacts, including complete animal bones [1][3]. Group 2: Settlement Structure - The layout of the house sites indicates a centralized settlement structure, which is crucial for exploring the forms of early Yangshao settlements and social development processes [3]. - Two segments of a circular trench were revealed, indicating a defensive nature, with features such as a semi-convex entrance and surrounding postholes that may have served as a fence [3][4]. - The combination of the semi-convex entrance, "gatehouse," and "fence" structures represents a significant finding in the Guanzhong region, marking the first discovery of such features [4].

Core Viewpoint - The Lianjiazhuang site in Shanxi Province has been excavated, revealing significant archaeological findings that contribute to understanding the cultural characteristics of the southeastern Jin region during the same period [3][7]. Group 1: Site Overview - The Lianjiazhuang site is located approximately 0.5 kilometers west of Lianjiazhuang Village in Qinxian County, Shanxi Province, covering an area of about 200,000 square meters [3]. - The site has been severely disturbed by agricultural activities and construction projects, with archaeological remains found primarily beneath the plow layer and no cultural accumulation layers identified [3]. Group 2: Archaeological Findings - The excavation revealed a single type of archaeological feature, specifically ash pits, with no direct stratigraphic relationships among the remains [5]. - The pottery discovered at the site predominantly consists of gray and brown pottery, with mud-gray pottery being the most common type [5]. - Decorative features on the artifacts include cord patterns, basket patterns, and additional raised patterns, with some vessel rims exhibiting a scalloped design [5]. - The main types of pottery include various jars and urns, with a smaller quantity of bowls, basins, and pointed-bottom bottles. Two distinct categories of urns and jars were identified based on their lip and rim characteristics [5]. Group 3: Cultural Significance - The Lianjiazhuang site shares geographical proximity and cultural similarities with the Dongcun site, reflecting both northern and southern regional influences while maintaining unique characteristics [7]. - The findings from the Lianjiazhuang excavation provide new data for further clarifying the cultural features of the southeastern Jin region and exploring interactions with other regions such as southwestern and central Jin [7].
