Gansu is one of the cradles of the Chinese nation and an important birthplace of Chinese civilization. Gansu has a long ancient history and culture, and was once an important node of the Silk Road. The ancient Silk Road is 2440 kilometers long and runs through the land of Gansu. Nowadays, there are numerous historical and cultural related scenic spots in Gansu Province, enjoying high reputation nationwide and even globally. Dunhuang murals are a topic that must be brought up in Gansu. Firstly, the restorer needs to stand on a scaffold, hold a grouting pipe, insert it into the gap between the mural and the wall, suck the prepared adhesive material into a syringe, and then pour it into the hollow part of the mural through the grouting pipe. Then, the mural is supported by a wall panel to stick it back to the wall. The program may seem simple, but in fact, it tests the skills of the repairman. Secondly, overall disclosure. In areas with high air humidity, the moisture on the wall can cause damage to the surface of the mural. To "remove it as a whole", the repairman first fixes the front mural, then opens the wall and installs a metal frame on the back of the mural. After the frame is set up, the repairman can hang the mural on the newly built wall. After completing a series of procedures, he will find that there is a distance of eight to ten centimeters between the mural and the wall. Next, whether it is a wall with abundant water or an earthquake, it can reduce the damage to the murals. Finally, paste the mural. With the advancement of technology, engineering and technical personnel have discovered that modern technology can be used for systematic analysis of mural samples from the inner turning path. Advanced technology can help restorers comprehensively grasp the "production materials" and "process information" of the mural, and then select soil with exactly the same composition as the original base material to use as the main material for "repair" and "pasting" after the mural is uncovered. After the selection of materials is completed, the restoration engineer carefully carries out the restoration according to the principle of not changing the original state of the cultural relics and the principle of being identifiable. According to the unique technique of the restorer, many murals have been perfectly restored. There is a mural of a Buddha statue, most of which has fallen off and only the lower lotus seat remains. The monks hope that the mural can be restored to its original state.
