Protection is not about shelving cultural relics, allowing historical and cultural heritage to enter daily life is the best way to protect them. "No matter how cold the weather is, every wall must be carefully examined so that the Great Wall can be 'treated' in a timely manner." In the section of the Great Wall in Dazhuang, Yanqing, Beijing, Great Wall protector Wang Dongwang braved the cold wind and walked on the wall, clearing weeds and taking photos with his phone when encountering cracks. Since the establishment of the Great Wall Protector System, this team has gradually grown, with over 6000 protectors. Their daily efforts and persistence have gathered a solid force to protect the Great Wall and inherit culture. Cultural relics are the living history and the confidence of culture. From the Spring and Autumn period and the Warring States period to the Ming and Qing dynasties, the construction of the Great Wall lasted for more than 2000 years and is the largest and most widely distributed historical and cultural heritage in China. Not long ago, the National Cutural Heritage Administration issued a notice on further strengthening the protection of the Great Wall, requiring all regions to conscientiously improve policies and measures, increase efforts and strictly protect the Great Wall in accordance with the law in a responsible attitude towards history and the people. The Great Wall has an irreplaceable important value and position in the history of Chinese civilization and the development of traditional Chinese culture. It is of great significance to do a good job in the protection of the Great Wall. After years of exploration and practice, "always putting protection first" has become a consensus, and the protection of the Great Wall is becoming increasingly effective. To make the Great Wall shine with a new era, we must constantly make breakthroughs and progress in how to protect it. What kind of philosophy can guide what kind of action. To do a good job in protecting the Great Wall, it is necessary to uphold the correct concept of Great Wall protection. As some scholars have pointed out, today's Great Wall no longer has its original military defense function, why do people still love it? It is its real and magnificent material existence that awakens people's connection with the past. Therefore, the protection of the Great Wall should adhere to the principle of "minimal intervention", and we should properly protect the authenticity, integrity, and historical style of the Great Wall. For sections of the Great Wall where buildings still exist on the ground, the main focus should be on maintaining structural safety, preserving historical information, and protecting the historical environment and style; For historical sites of the Great Wall that have collapsed or disappeared on the ground, the focus should be on preserving the site in its original state, rather than rebuilding or conducting large-scale repairs on the original site. We do not advocate large-scale reconstruction and reconstruction because there is a more scientific way to protect the Great Wall. In the past, the protection of the Great Wall was mostly focused on repairing where it was damaged, with a focus on salvage protection. During the repair process, the work of various professional technicians was also relatively scattered; Nowadays, the protection of the Great Wall has entered the stage of scientific protection and repair, with a greater emphasis on both rescue protection, research protection, and preventive protection. For example, Beijing has selected the Yanqing Dazhuangke section of the Great Wall and the Huairou Jiankou section of the Great Wall as pilot sites for research-based repairs, introducing archaeological elements and emphasizing both repair, archaeology, and research. This allows archaeologists, designers, surveyors, and construction personnel to collaborate and cooperate in all aspects, making "research and repair" a reality. It is necessary to summarize and promote relevant experiences in order to do a good job in the protection of the Great Wall, and to make the new model of research-based repair more perfect. It should also be noted that protection is not about putting cultural relics on the shelf. The best way to protect historical and cultural heritage is to let it enter daily life. In Yongchang, Gansu, the local area not only renovated and built the Great Wall Cultural Exhibition Center, but also
