Since the 1980s, when Dunhuang restoration personnel participated in the salvage protection of the Maijishan Grottoes, the protection work of Maijishan has increasingly emphasized scientificity and standardization. This year, the Dunhuang Academy collaborated with the cultural heritage team of Fudan University to develop a plan for the protection of cultural relics in Maijishan, using cultural landscape methodology to reassess the value of Maijishan Grottoes and comprehensively promote the transition from "salvage protection" to "preventive protection". Maijiya is located in the remaining veins of the Qinling Mountains. The mountain is like a farmhouse accumulating wheat, and the 100 meter cliff is covered with small and large holes, witnessing the superb skills of ancient craftsmen in climbing cliffs and suspended operations. In the 1950s, during a survey, nearby carpenters were organized to carry boards and install ladders, and the technique of climbing clouds through niches and ridges was recreated using perforated stakes. But this traditional wooden ladder climbing method cannot meet the needs of large-scale public opening. In the 1970s, the National Cutural Heritage Administration organized and implemented an 8-year rock mass reinforcement and plank road construction project, creating conditions for the public to watch the millennium treasures closely. After the reinforcement of the rock mass and the construction of the boardwalk, the Maijishan Grottoes opened up to the world with a true and complete appearance. Many caves that had been abandoned for a long time since the Song Dynasty welcomed human traces again hundreds of years later. The statues, murals, and inscriptions in the caves and niches have been systematically organized, copied, and published, becoming important objects for historical research. These physical remains showcase the social changes, north-south exchanges, ethnic integration, and the rise and fall of religious beliefs in China from the 5th to the 13th century. The statues, costumes, and inscriptions seen in the caves provide irreplaceable historical materials for the social history, military history, and ethnic integration history of Northwest China. Since the 1980s, large-scale catalogs and research achievements have been continuously published, which has provided us with a more comprehensive understanding of the overall evolution of Chinese grotto temples and ancient social life. In 2014, the Maijishan Grottoes were included in the The World Heritage List as an important part of the "Silk Road: the road network of Chang'an Tianshan Corridor", promoting us to reassess their universal value in a broader perspective. Tianshui, formerly known as Qinzhou, is located at the gateway of Longyou, connecting the Central Plains with the Western Regions and Tubo. Maijishan itself is a product of cultural exchange along the Silk Road. The natural landscape of Maijishan is also dependent on its value. Qinzhou is known as the 'Jiangnan on the Long River'. After returning farmland to forests, Maijishan has restored its historically superior natural scenery. During the rainy season, smoke and clouds linger, and the scene of the ancient book 'Grain Accumulation Smoke and Rain' can be recreated. Due to its location on the northern edge of the West Qinling Mountains fault zone, the major earthquakes of the Sui and Tang dynasties in history caused cliff wall fractures, and there are still ancient cave ruins that have crashed at the foot of the mountain. Based on over half a century of research, the protected objects have extended from single murals and sculptures to the overall protection of mountains, landscape environments, and underground cultural relics burial areas. After Maijishan was placed under the management of Dunhuang Academy in 2017, relying on the experience of world heritage site management, systematic archaeology and archaeological reports were continuously carried out to further extract and interpret the multiple values of Maijishan. Maijishan is not only a world cultural heritage site, but also a spiritual belonging for the people in the surrounding villages. There are more than 600 households in Maiji Village and Caotan Village at the foot of the mountain. The repair of grottoes, construction of boardwalks, transportation operation, and interpretation services have long relied on local labor transportation and talent cultivation. The villagers regard the Maijishan Stone Cave as a source of bloodline and cultural pride, and are willing to inherit and protect it from generation to generation. The Maijishan Art Research Institute publishes popular science books and cultivates "little interpreters" to transform the concept of heritage preservation into community identity and daily practice. The site selection, excavation, restoration, and modern protection of Maijishan together constitute a cultural epic of over 1500 years. From the perspective of overall protection, we found that creating a humid climate of "wheat accumulation and smoke rain" has brought difficulties to the treatment of cave seepage; Good forest vegetation allows birds and insects to coexist, but also poses a challenge of biological diseases to cliff caves. In order to preserve this precious cultural heritage, Maijishan calls for more social forces to participate, using scientific methods and intergenerational commitment, dedicating themselves to protecting the country's treasures and safeguarding the touching smile that spans thousands of years.
