In fact, patina is a proper term in the field of antiques. This is because some Wan Wen have been played with for a long time, and the human body's oil and Wan Wen are combined with each other, and a protective film is formed by oxidation. The Buddha statues in Longmen Grottoes in Luoyang were pulled out by tourists because many tourists wanted to touch these Buddha statues themselves out of curiosity, thinking that just touching them would not be a big deal, but because many people thought so, cultural relics in many scenic spots were directly destroyed.
For us tourists, the most important thing is to protect the environment and cultural relics of the scenic spot. The reason why these cultural relics have been circulated for hundreds or even thousands of years without being destroyed is largely due to the proper custody of the former people. For us, while enjoying the beautiful scenery of the scenic spot, we should also pay attention to our personal qualities, and we cannot but abide by the regulations of the scenic spot and destroy the environment of the scenic spot at will.
For scenic spots, a sign can be set up next to the stone statues that are often touched to remind tourists that these cultural relics need to be protected. Many tourists reach out and touch it because they don't realize the seriousness of the problem. I believe many people will definitely not touch this brand for the sake of cultural relics protection. At the same time, reminders should be set near the scenic spots, which can correct some uncivilized behaviors in time. For many people, it is caused by herd mentality. They think there is nothing wrong with others touching it, and it is definitely no problem to touch it yourself. If you don't touch it yourself, you may suffer. And if you set a reminder at this time, you can stop these uncivilized behaviors in time.
Finally, I want to say that civilized travel and civilized sightseeing can not only protect cultural relics, but also show our noble character.
