Why is graffiti never seen on the Great Wall of China?
Graffiti is always being put on the wall: “The Great Wall of China sees some four million visitors a year and too many of them leave graffiti behind, usually their own names or expressions of love. Managers of the Juyongguan section have devised a novel plan to fight the problem: they have built a bogus wall of marble bricks near the most visited section of the wall in Badaling and are offering it up for carving at a cost of $120 per brick.
