The Great Wall of China, one of the greatest wonders of the world, was enlisted in the World Heritage by UNESCO in 1987. Just like a gigantic dragon, the Great Wall winds up and down across deserts, grasslands, mountains and plateaus stretching approximately 6,700 kilometers (4,163 miles ) from east to west of China. With a history of more than 2000 years, some of the section of the great wall are now in ruins or even entirely disappeared.
