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 down across deserts, grasslands and mountains stretching approximately 6,700 kilometers from east to wes of China.
With a history of more than 2,000 year, some of the sections of the Great Wall are now in ruins or even entirely disappeared. However, it is still one of the most appealing attraction all around the world.
