"He who has never been to the
Great Wall is not a true man."
Many myths and legends have emerged about the Great
Wall. Unfortunately, the most famous one, that it is the only
man-made structure on earth that can be seen with the
naked eye from outer space, is untrue. At best, the wall can
be spotted during a low orbit, but even then only if sunlight
and weather permits it.
