As a symbol of human civilization and world cultural heritage, protecting the Great Wall is to inherit the "Great Wall spirit" and protect the spiritual home.
        Jiayuguan City has actively built a research platform for cultural relics protection to jointly "care" the cultural relics and their carriers. Jiayuguan City is the most spectacular and well preserved ancient military Castle among the more than 1000 passes along the Great Wall in the Ming Dynasty. It was listed as a world cultural heritage by UNESCO in 1987. However, affected by natural factors such as strong wind and sand and strong sunshine in Northwest China, some buildings have diseases. Since 2011, the city has started the Jiayuguan cultural heritage protection project to protect and repair 10 sub projects such as Guancheng wooden structure building, oil decoration color painting, Xiluo city protection and maintenance, wall protection and anti-seepage drainage, rammed earth Great Wall Protection and maintenance, lightning protection, security and fire protection system engineering, so as to reproduce the past historical features of the world cultural heritage.

        Zhang Bin, director of the Great Wall Protection Institute of Jiayuguan Silk Road (Great Wall) Culture Research Institute, said: "the life of the Great Wall is continued through preventive protection, and a protection management model from daily monitoring to comprehensive prediction, early warning to timely protection is formed through the scientific and technological data of heritage monitoring, so as to minimize the damage to the Great Wall by external factors."
        Jiayuguan cultural relics protection unit uses a variety of scientific and technological means to create a heritage protection and management mode of "risk monitoring - Comprehensive Prediction - early warning - immediate treatment" through meteorological monitoring, cultural relics and environmental monitoring, so as to minimize the damage caused by various hazard factors to the great wall and control the diseases endangering the safety of the Great Wall.

        Zhang Xiang, deputy director of the cultural heritage monitoring center of Jiayuguan Silk Road (Great Wall) Cultural Research Institute, said: "our monitoring system mainly carries the monitoring of the world cultural heritage in Jiayuguan. All the monitored data are integrated into the monitoring system platform behind us, and then through the display of data, We can quantitatively analyze what the whole existing state looks like. "
        After years of protection and repair, now Jiayuguan City, which shows the magnificent scene of "eight thousand miles in the West and one hundred and two times in the east of Xiongguan", is no longer a "Twilight old man" in his 600s, but a "heroic soldier" with strong bones and new face, which also attracts tourists from all over the country to see the style of Guancheng.

        Tourist Tang Peiyuan said, "we turned from Yumenguan. I turned this pass. I think this pass is the most beautiful and well preserved one I've ever seen. It's the most magnificent. Moreover, it's well preserved and well managed. "
        Up to now, Jiayuguan City has implemented rescue protection and repair of Jiayuguan City and the 43.6 km long Great Wall, which has solved the disease factors that endanger the safety of cultural relics for a long time. The restoration of the Great Wall in Jiayuguan City has also changed from rescue protection to preventive protection, realizing a high level of comprehensive protection and utilization.
