As more and more people in China have money to travel and have fun, the number of people visiting Dunhuang Mogao Grottoes often reaches more than 7,000 per day. It is reasonable to think that about 2000 people a day. A large number of tourists come to this cave, which is very unfavorable to the murals in the cave and takes a long time to recover.
2. Serious damage
Non-renewable Dunhuang murals are being destroyed by man-made environmental pollution. A recent news is even more shocking: more than half of the murals in Dunhuang Mogao Grottoes are infected with an alkali-wasting disease called mural cancer. This cast a shadow over the centennial celebration of Mogao Grottoes, the world's largest Buddhist art treasure house.
According to experts from Dunhuang Research Institute, the murals in Mogao Grottoes are soil cultural relics, which have been very fragile after thousands of years of tempering. After the opening, the murals in the cave were constantly attacked by air dust and carbon dioxide, and the original color gradually deteriorated.
Statistics show that in recent years, the number of tourists to Dunhuang is over 600,000 every year, which is a number that scares cultural relics experts. Because some experts in cultural relics have done experiments: let 40 people stay in the cave for 37 minutes, and the temperature, humidity and carbon dioxide content in the air are six times higher than normal. The changes brought by 600,000 people can be imagined.
