【Hot attention from Chemical Machinery and Equipment Network ] On March 22, the Beijing Municipal * Yanqing Branch issued a notice on Weibo to investigate and seize 3 People who violated the law.
At present, according to the relevant provisions of the "Public Security Administration Penalty Law of the People's Republic of China", the three have been administratively detained and fined.

Although the "Administrative Measures on the Protection of the Great Wall of Beijing" and the "Regulations on the Protection of the Great Wall" clearly prohibit activities that endanger the safety of the Great Wall, such as depicting, smearing, and damaging, tourists engraving on the Great Wall bricks was once a common situation on the Great Wall.
.
Nowadays, punishing tourists who commit wrong behaviors is actually a reasonable act according to the law.
But for the Great Wall, once the brick body is damaged by the lettering, it is difficult to repair it.
According to the introduction of relevant experts, repairing the engraved brick body will further damage the Great Wall brick if it is polished.
If you want to fill in the engraving gap, improper selection of materials will destroy the overall >

In fact, the Great Wall is not a special case.
Many architectural monuments or large-scale cultural relics in China have engravings such as "Visit here", and the difficulty of their restoration is no exaggeration.
Severe punishment is undoubtedly an effective means to reduce these occurrences and protect the integrity of cultural relics.
But are we really at a loss for those cultural relics that have been destroyed? In fact, it is not.
Although it is quite difficult, if you find the right method and use the right tools, you can actually complete part of the repair and maintenance work within a limited range.

Take the restoration of the Great Wall as an example.
In fact, there have been news related to the restoration of the Great Wall before, and there have been farce in it.
The Desheng Fort in Datong Town of the Great Wall of the Ming Dynasty was restored into an antique building because of the use of antique bricks in the restoration process, which caused the overall >Therefore, the key to the restoration of ancient buildings lies in the material and the degree of restoration.

In fact, with the development of scientific instruments, there are now many means of material analysis.
It is not difficult to understand the materials of the Great Wall bricks.
For example, laser Raman spectroscopy can be used to analyze the mineral composition in masonry with the help of vibration spectroscopy technology, and the types and structural characteristics of masonry can be analyzed by X-ray fluorescence spectrometer and X-ray powder diffractometer, so as to help ancient building restoration staff quickly Find the right and correct repair materials.
For example, with the help of CT machine, ultrasonic flaw detector, etc.
, non-destructiveDetector , you can understand its architectural structure without damaging the original structure of the Great Wall, has been piling up inside the way, provide a reference for subsequent repair practices.

After these preparations are completed, we can consider using the same raw materials to repair obvious and important damaged structures and surfaces while preserving the integrity of the building as much as possible, so as to achieve the purpose of strengthening the Great Wall and restoring the Great Wall.
But in fact, even so, there is still a problem with the restoration of the Great Wall, which is whether the historical value of the restored Great Wall itself has been changed.
For the Chinese, the Great Wall is not only a historical miracle, but also a symbol of national history.
No matter how "seamlessly" we have repaired, it has still been destroyed.
Therefore, compared with the later restoration and protection work, the awareness of the masses is the key to helping the preservation of cultural relics*.
