The archaeological achievements of Sanxingdui Site are well-known in the world, showcasing the civilization achievements of more than 4000 years ago, providing more powerful archaeological evidence for the diversity and integration of Chinese civilization, the mutual influence between ancient Shu civilization and Central Plains civilization, etc. The protection and restoration of cultural relics is a long-term task, which requires increasing national support, strengthening the construction of talent teams, promoting the rigorous and meticulous craftsmanship spirit, working hard one by one, and achieving greater results. As a practitioner who has witnessed the archaeological excavation and cultural relic protection of Sanxingdui for more than 30 years, I deeply understand that "long-term dedication" is not only a scientific methodology that must be adhered to in cultural relic work, but also a cultural sentiment that has been passed down from generation to generation by cultural relic protectors. Archaeological excavation: Adhering to decoding the code of civilization through time. The Sanxingdui site, discovered in 1927, has a history of nearly a hundred years of archaeological exploration, which has been passed down from generation to generation by ancient scholars. After the first excavation led by American archaeologist Graham in 1934, the footsteps of our ancestors never stopped. In December 2019, the Sichuan Provincial Institute of Cultural Relics and Archaeology, based on the inheritance of previous achievements, cleared a bronze large mouth statue from the Shang Dynasty during the established archaeological exploration process, thus starting a new round of archaeological excavation. We have collaborated with over 45 cultural and museum institutions and research institutes in China to practice the archaeological concept of "Chinese characteristics, Chinese style, and Chinese style" through interdisciplinary cooperation, setting a new benchmark in the industry. The rigor of archaeological work lies in every meticulous operation. At first, in order to confirm the opening layer and shape boundary of the "artifact pit" to which the Bronze Big Mouth Zun belonged, archaeologists repeatedly scraped the surface with a hand shovel and spent a month presenting its outline clearly: this northeast southwest rectangular relic is 5.7 meters to 5.84 meters long and 2.2 meters to 2.71 meters wide. The rich metal remains inside the pit confirm its sacrificial pit attribute and is named the No. 3 sacrificial pit. The confirmation of pits 4 to 8 followed the same rigorous process, resulting in the excavation of over 17000 cultural relics that shook the world. From 2022 to early 2024, the archaeological team spent two years cleaning up five sets of large building foundations at the Zhenwu Palace site in the northern part of the Sanxingdui site, and unearthed 4739 artifacts such as pottery, jade, and stone tools. Among them, there are various types of jade artifacts, including important objects such as jade figures, jade teeth, and jade spears. Through meticulous cleaning, we have successfully restored the complete production chain of jade artifacts from raw material sorting, preliminary processing to molding, and identified this as the Sanxingdui jade stone tool production workshop. In a pier at a building site, the team discovered agate raw materials that had been filled twice and were the size of peanut kernels. In order to preserve archaeological information, the staff measured, recorded, and extracted about 19000 agate raw materials one by one. In order to present the overall layout of the workshop clearly, piles of raw materials, blanks, and waste materials are still preserved in their original positions, and the refinement of excavation work is still ongoing. Over the past century, every archaeological achievement has originated from the daily perseverance and meticulous operation of ancient archaeologists. This history of struggle is a vivid portrayal of the craftsmanship of cultural relics craftsmen who uphold their original intentions with ingenuity and persist towards the distant future, providing key support for interpreting the profound heritage and infinite charm of Chinese civilization. Technological breakthroughs: Using the spirit of craftsmanship to solve protection problems and carrying forward the rigorous and meticulous spirit of craftsmanship, which is reflected in the practice of cultural relic protection as a persistent effort to overcome technical problems and a firm adherence to scientific laws. In 2019, 104 ivory tusks were unearthed from Pit 3 of Sanxingdui, with a moisture content of nearly 50%. Most of the tusks were layered and cracked, and some cracks were filled with soil. Due to the degradation of most of the internal organic collagen, the original tissue structure and mechanical properties are lost, and the morphology is maintained solely by water surface tension and soil adhesion. After the ivory was unearthed, the long-term buried equilibrium system was disrupted, and dehydration and cracking became a major problem that urgently needed to be solved. In the face of challenges, we have launched a four-year battle for protection with the perseverance of 'enduring for a long time'. To provide a stable environment for ivory, we have transformed three basements into "Ivory Intensive Care Units" with constant temperature and humidity, and set storage conditions of 5 ℃ constant temperature and 90% constant humidity. Cultural security personnel monitor and record the moisture content, surface strength, cracks, color, and other indicators of ivory every week. They regularly replace moisturizing cotton paper and collect microbial samples, accumulating more than 6000 sets of monitoring data. Based on the data, maintenance measures are dynamically adjusted to ensure that the ivory is basically maintained in its unearthed state, which has bought valuable time for the research and development of dehydration reinforcement technology. Cracking technological bottlenecks requires cross domain collaboration. We have joined forces with several cultural and research institutions, including the Chinese Academy of Cultural Heritage, Henan Provincial Institute of Cultural Relics and Archaeology, Jingzhou Cultural Heritage Center, and Shanghai University, to conduct joint research on high water content ivory as a "non-uniform material". The team adopts cross-linking and filling reinforcement as technical routes, and conducts experiments using materials such as acrylic acid salt and silicon aluminum composite sol. Until July 2024, the ivory samples processed in the experiment finally achieved long-term storage under conventional conditions in the cultural relics warehouse, and the ivory dehydration reinforcement protection technology achieved breakthrough results. Throughout the entire R&D process, the team has always adhered to the principle of "not rushing or speeding up". All experimental materials, process measures, and protective effects have been scientifically and rigorously evaluated and verified, demonstrating the profound connotation of the "rigorous and meticulous craftsmanship spirit" through practical actions. Fine management: Over the past two years, with the strong support of the national cultural relics administrative department, about 200 cultural heritage restoration workers have completed the protection, cleaning, and restoration of more than 4000 unearthed bronze, jade, gold, and ivory carvings through scientific methods, as well as interdisciplinary research work. As of now, 5391 cultural relics have been finely processed after the new round of archaeological excavations, achieving the established goal of "each piece has archives and every item has records". The cultural heritage preservation work always adheres to the principle of "minimal intervention, maximum access to historical information", and customizes protection and restoration plans for cultural relics of different materials and preservation conditions. Taking the protection of newly unearthed gold masks as an example, we have innovatively used 3D scanning, modeling, and photosensitive resin printing technology to develop protective supports with high adhesion, stability, and transparency, achieving the three in one protection goals of "exhibition, research, and preservation". There is a code of civilization hidden in the details. The cultural security personnel did not miss any "clues" and comprehensively used multidisciplinary methods such as X-ray CT, neutron imaging, and 3D modeling to discover the earliest examples of the use of bronze core bone technology, scientifically explaining the difficulties in forming complex, slender, and curved objects; With the help of technology instruments such as ultra depth microscopes, scanning electron microscopes, and infrared spectroscopy, silk traces were discovered on more than 100 objects, filling the gap in silk archaeology in the Ba Shu region during the Yin and Shang dynasties. The achievement of these results is the inevitable result of the process of perseverance and pursuit of quality in the pursuit of long-term success. Talent cultivation: Building a solid foundation for inheritance and strengthening the construction of talent teams through the construction of a team of talents, which is at the core of the development of cultural relics. Talents are the primary resource for the cultural heritage industry and the fundamental guarantee for achieving long-term success. To this end, we are committed to building a diversified talent training system and injecting continuous vitality into the cause of cultural relics protection. In terms of collaborative training, Sichuan Provincial Institute of Cultural Relics and Archaeology has established strategic partnerships with 17 institutions including the Palace Museum, China Academy of Cultural Heritage, and China Silk Museum. Adopting the traditional model of "master apprentice", it has trained 20 talents in bronze, gold, jade, ivory conservation, and interdisciplinary research. Relying on provincial-level cultural relic restoration skills master studios, "mentorship" projects and other platforms, we have hired industry leaders to pass on their skills, implemented "order based" training, and cultivated a total of 12 skilled personnel in archaeology and cultural relic protection. At the same time, we will adhere to open communication, dispatch one visiting scholar to study at a foreign research institute, and select eight students to participate in training courses on cultural relic protection and restoration skills at home and abroad, as well as exchanges with relevant institutions. In terms of skill incentives, we have held the Provincial Vocational Skills Competition for the Cultural Relics Industry for two consecutive years, selecting "cultural relic craftsmen" through the model of "competition promotes learning and competition promotes construction". In July of this year, Sichuan sent 12 contestants to participate in the second National Vocational Skills Competition for Cultural Relics Industry, winning 2 first prizes, 4 second prizes, and 5 third prizes, ranking first in the country in terms of the number of awards won. In the future, we will strictly implement incentive policies, improve the professional title evaluation system, and focus on cultivating "National Cultural Relics Master Craftsmen". At the same time, we will increase talent selection and publicity efforts, so that the spirit of cultural relics craftsmanship can become a prevailing trend in the land of Sichuan and Sichuan. In terms of system construction, we are promoting the formation of a three in one cultural and museum talent training system consisting of "institutional education+mentorship+professional training", deepening cooperation with universities, and exploring targeted training models for general talents; Continuously smooth the assessment and inclusion of cultural relics protection and restoration talents, and establish a "green channel" for professional title evaluation, breaking down barriers and attracting more young talents to join the cultural relics protection industry. It is gratifying to see that more and more young people are joining this ranks - the 15 post-90s cultural protection teachers in the cultural protection team have engraved the instructions of "one by one, long lasting achievements" on the back of their work badges, constantly reminding themselves not to forget their original intentions. Their growth is the future and hope of the cultural heritage industry. Currently, we are taking the construction of the Sanxingdui National Cultural Relics Protection and Utilization Demonstration Zone as the fulcrum to fully promote the second phase of the ancient Shu civilization protection and inheritance project, focusing on three aspects of work: first, deepening the archaeological and interdisciplinary research of the Sanxingdui Jinsha site, and strengthening the overall and systematic protection of the ancient Shu civilization relics; Secondly, to enhance the level of heritage interpretation and exhibition, and expand international communication channels; The third is to innovate the sustainable development model of heritage sites, striving to establish a sound system for the protection and inheritance of ancient Shu civilization by 2028, further expanding its international influence, and providing strong support for the creative transformation and innovative development of excellent traditional Chinese culture.
