This can reduce tourism in our country. It will also create a negative image in the mind of foreign tourist.
First of all I will try to stop them. I will explain them that how they are destroying the beauty of the beautiful monuments. I they will not do as I said I will call the police.
Other people should also stop such kind of people. If all they people raise voice against it then there will be no one who will dare to scribble on the monuments.
