"Walking Through the Great Wall of China" is a magic trick performed by the illusionist David Copperfield, in which he apparently enters the Great Wall of China from one side and emerges on the other side in front of a live audience on both sides of the wall and over it. This illusion was performed in his ninth TV special "The Magic of David Copperfield VIII: Walking Through the Great Wall of China" (1986). It is one of the illusions Copperfield performed only once in his career.
