Documenting tangible cultural heritage using 3D modeling techniques is gradually becoming an indispensable component of archaeological practice. The 3D modeling techniques based on photogrammetry and LiDAR scanning enable high-accuracy and high-realistic reconstruction of archaeological sites, and have been proven a powerful tool for documenting archaeological excavations. However, dynamically documenting an ongoing excavation using these techniques is still considered tedious, time-consuming, expensive, and dependent on expertise. Moreover, the application of 3D modeling techniques in archaeological excavations still faces some technical challenges, such as modeling with multi-source and multi-scale data, fusing local models at different times into a whole, achieving fast modeling while GPU workstations are not available in the field, and evaluating the quality of 3D models. As a result, there are still very few archaeological teams deeply engaged in dynamic documentation with 3D modeling techniques, and traditional drawing sketches and taking photographs still dominate. In these senses, documenting the archaeological excavation at the Yunxian Man site (located in Hubei, China) is an invaluable opportunity for exploration and practice. Archaeologists determined to conduct dynamically documenting at the beginning of the 6th excavation project for the site, and established a rotation system to reconcile physical excavation with digital preservation. Through repeated practice and communication, we proposed a workflow and pursued several new methods to enhance the feasibility of dynamically documenting, and obtained 4D models of the ongoing archaeological excavations. In 2022, the Yunxian Man site unearthed the most intact fossil of hominin cranium from about one million years ago in the Eurasian continent, preserving important and scarce anatomical features of early humans in Asia. As the original taphonomic context of the fossil corroded away during physical excavations, the digital documentation consisting of 4D models serves as permanent original data source in subsequent archaeological research. Moreover, we obtained cross-scale 3D models from geographical environment to archaeological site, excavation area, and cultural remains, and all of these 3D models are in an actual, unified coordinate framework. Thus, we can contribute to multidisciplinary cross-collaborative research through data sharing. Considering that digital documentations serve a great value in archaeological research, this paper focuses on sharing the workflow and methods to facilitate digital preservation for more archaeological projects.

Chinese scholars' performance in international academic community and research on foreign archaeology has brought hot discussion about the internationalization of Chinese archaeology. Based on the databases of the China National Knowledge Infrastructure (CNKI) and the Web of Science core collection (WoS), this paper collected archaeology-related papers published by Chinese scholars in Chinese and world core journals (CCJs and WCJs for short), then filtered translated and original articles about foreign archaeology in CCJs, as well as all original archaeological articles in WCJs. Using Excel, CiteSpace and VOSviewer visualization software, we analyzed these data to give a bird's-eye view of how archaeology research in Mainland China has become internationalized. Chinese archaeology has seen active-interrupt-active phases characterized by learning from foreign academics in the last century. Over the past two decades, the number of articles published in WCJs by scholars from Mainland China has increased significantly, and most research topics are at the forefront of international scholarship. Collaboration networks largely expanded, with the number of Mainland China–led articles increasing significantly. Archaeological papers written by researchers from Mainland China have appeared in a more extensive range of journals, including those with high impact factors. However, articles related to joint Sino-foreign archaeological projects were mostly published in CCJs. The archaeology-related articles published by Chinese scholars in WCJs occupied only a small proportion of all archaeological articles in WCJs. Compared to articles in CCJs, the number of those published by Chinese scholars in WCJs is a drop in the ocean. Therefore the internationalization is not yet a dominant trend and with the introduction of the new inward-looking policy we need more time to observe where the trends of internationalization and localization in Chinese archaeology are heading.

This article collected papers published by Chinese archaeologists in Chinese and World core journals (CCJs and WCJs for short) in the past century. Based on bibliometric analysis, the general characteristics and trends of Chinese archaeology were summarized. In a macroscopic perspective, historiography-rooted archaeology focusing on historical periods and central areas of China and preferring traditional archaeological methods (mainly a culture-historical paradigm) will continue to occupy a leading position in China. Simultaneously, interdisciplinary research and internationalisation will likely continue to develop and diversify Chinese archaeology, though the speed is unknown due to the impact of the pandemic. In comparison, more attention needs to be paid to theoretical research and to publishing more results of historical archaeology in WCJs. [ABSTRACT FROM AUTHOR]
