This is the standard advocated by the United Nations. General cultural relics should be well preserved; Maintain the original appearance-meticulously repair: for the repair of incomplete buildings (ancient relics), it is necessary to "maintain the original appearance to preserve its truth". The Venice Charter puts forward two restoration principles recognized by all countries in the world: the restored and filled parts must form a whole with the original parts, and maintain harmony and consistency in the landscape, which will help to restore but not reduce its artistic value, historical value, scientific value and information value; The added part must be different from some parts, so that people can distinguish between historical and contemporary additions and safeguard the historicity of cultural relics. In addition, the reinforcement and maintenance should be as little as possible, which is the principle of necessity; Reconstruct cautiously: Some very important historical buildings were destroyed for some reason. Because they are important local characteristics and signs, it is necessary to rebuild them if conditions permit. The reconstruction is unforgettable. However, the reconstruction must be cautious and verified by experts, because the reconstruction will inevitably lose the authenticity of history, spend a lot of money and destroy the relics. In more cases, it is more valuable to preserve the remains; Utilization is based on the premise of not destroying the heritage. The use of historical and cultural heritage is based on the premise of not destroying the heritage, and it is best to continue the original use method. It can also be used as a museum and tourist attraction to carefully prevent damage; Maintain the pattern characteristics of historical blocks and ancient cities. Focus on protecting the plane layout, azimuth axis, road skeleton and river network of historical blocks and ancient cities; Protection of characteristic architectural style: protection of characteristic architectural style, including architectural style, height, volume, material, color, plane layout, relationship with surrounding buildings, etc. It is very important to control the appropriate building scale-height and volume. Remember that now and now are different, and it is not required to be very high or large. Protecting the historical environment: Things are inseparable from the environment in which they exist, and they cannot exist without the environment. The significance of the historical and cultural heritage environment is even more important, and the important topography, landforms, gardens and metallurgy, water bodies, flowers, trees and their characteristics that are important, distinctive and related to history should be protected; Uncertain old cities, villages, streets and ancient buildings should not be demolished for the time being. Many remote places, especially mountainous rural areas, ancient towns, ancient villages, ancient streets and ancient buildings, are not key cultural relics protection units, but they are also historical and cultural heritage with considerable value. The local people don't know if they have the financial resources and opportunities to ask experts for appraisal. It is best not to dismantle this situation for the time being, so as not to cause regret, and then deal with it according to the situation after being demonstrated by experts.
