Liaoning tourist Wang Ying placed the last stop of her vacation in Ji'an, Jilin at the museum in this county-level city. Entering by swiping her ID card, putting on headphones, scanning the code to choose voice explanation, Wang Ying walked into the exhibition hall and quickly immersed herself in the local unique historical and cultural heritage. Such ordinary operations were difficult to implement in the past Guo Jiangang, Deputy Director of Ji'an Museum, said. It is very difficult for a county-level museum to independently develop a voice explanation system. In fact, this is a common problem faced by many small and medium-sized museums - limited resources, how to improve and upgrade? In 2021, nine departments including the National Cutural Heritage Administration issued guidance on promoting the reform and development of museums, proposed to implement the promotion plan for small and medium-sized museums, strengthen mechanism innovation, and effectively revitalize the resources of grass-roots museums. In 2022, Jilin Province launched the "Light up the Light of Culture and Museology" campaign, exploring the use of "big museums leading small museums" to assist small and medium-sized museums in using digital means for comprehensive quality improvement and upgrading. The Museum of the Imperial Palace of Manchukuo and the Changchun Institute of Cultural and Creative Innovation are responsible for the specific implementation of this plan. Soon, a software system based on cloud computing, big data and other technologies, the "Diaolong Cloud" museum operation cloud platform, emerged. Its name comes from 'Wenxin Diaolong', aiming to meticulously manage the museum, "said Ai Xuesong, director of the Information Department of the Manchukuo Palace Museum. The "Diaolong Cloud" focuses on ten functions related to the daily operation of museums, including collection management, collection display, audience reception, and event management. It helps small and medium-sized museums use advanced management technologies and experience to comprehensively improve management and operational efficiency. It also utilizes cloud technology to connect various museums through mini programs. Viewers can obtain more information about different museums online; Cultural relics departments at all levels can grasp the reception and cultural relics protection situation of each museum in real time according to different authorities. In the era of Smart Museum 2.0, it is necessary to achieve thorough perception and ubiquitous interconnection Ai Xuesong said. This case of using digital innovation to help improve the quality and upgrade of small and medium-sized museums has been selected as one of the "Top Ten Cases" for high-quality development of cultural relics in 2023. Nowadays, with the support of relevant policies and departments, this system is provided free of charge to various small and medium-sized museums in the province. This helped us save a lot of costs, "Guo Jiangang said. We have felt changes in all aspects Li Qiuhong, the director of Panshi City Museum, said. The application of "Diaolongyun" has brought more attention to this unknown small museum. In addition to increasing exposure, the management and curatorial capabilities of Panshi City Museum have also been significantly improved. Previously, we could only roughly count the number of visitors. Now that we can grasp information such as the age composition and origin of visitors, we can design exhibitions more targetedly, "said Li Qiuhong. At present, this action to upgrade the quality of small and medium-sized museums has moved from the software field to the hardware field. Many small and medium-sized museums are limited by inherent architectural deficiencies, and the preservation environment for their collections is not ideal. Problems such as water leakage and temperature differences can only be addressed by purchasing temperature and humidity control equipment, with limited effectiveness. In order to solve the security issues of collections in small and medium-sized museums, the "Light up the Light of Culture and Museums" action plan project team has collaborated with CRRC Changke to develop a "super large constant temperature and humidity cabinet" with the advantages of high-speed rail manufacturing and environmental control technology. It integrates various cultural protection needs such as fire prevention, theft prevention, dust prevention, insect prevention, constant temperature and humidity, and intelligent monitoring. Now, this "modular intelligent cultural relic shelter" will be installed and used in multiple museums. In Jilin Province, 28 museums have joined this quality upgrade campaign. Ai Xuesong said, "I hope that in the future, digital upgrades will cover more small and medium-sized museums, helping museums better serve the cultural needs of the public
