Many of them have been damaged to varying degrees. For example, in certain sections of the Great Wall, a large number of tourists have poured in. Plastic bags, mineral water bottles, waste paper, peels, and Coke cans can be seen everywhere.

Others are even more serious. The city walls have been graffitied by tourists, and in some places there are advertising papers posted on them.
