This article introduces several successful cases of cultural relics conservation to projects demonstrate major achievements by the Shaanxi Provincial Institute of Archaeology in the recent ten-year. This wide range of cases include the investigation and collection of archaeological information on site, on site conservation of fragile artifacts, on site conservation of large-scale cultural relics and features, excavation inside laboratory, research and manufacturing of the mobile laboratory for cultural relics conservation on site, archaeometallurgy and conservation of metal artifacts, research and conservation of textiles, research and conservation of murals, research and conservation of ceramic and porcelain, and so forth. Our division also made significant contributions on on-site cultural relics conservation and indoors conservation of cultural relics. In comparison with previous works, our division paid more attention to information extraction and research through the process of cultural relics conservation. Also, we emphasize on the conservation of the integrity of cultural relic information. Changes of working principles in cultural relic conservation not only allow us to provide more timely protection for unearthed artifacts but also archive significant results in relevant research.
