The Great Wall of China, one of the most appealing attractions of China and one of the greatest wonders of the world, was constructed by the Vassal states under Zhou Dynasty for defense purposes. The construction began during 7th century B.C. and was completed between the 14th and 17th centuries. The United Nations Educational, Scientific and Cultural Organization (UNESCO) recognized the Great Wall of China as the World Heritage in 1987.
Once the state of Qin was unified with China, China joined all the walls to impede invaders from northern China and extended them to more than 10000 li, which is equal to 5000 kilometers. Like a Chinese holistic dragon with a zigzag shape, the Great Wall of China stretches across mountains, plateaus, deserts, rivers and grasslands with a length of almost 6,700 kilometers. It is over 2000 years old and runs from East China to West China. Unfortunately, portions of the wall are in ruins due to lack of interest on the part of the Chinese Government. This magnificent piece of Chinese history touches the provinces of Shanhaiguan Pass, Liaoning, Hebei, Tianjin, Beijing, Shanxi, Inner Mongolia, Ningxia, Gansu and finally ends in Jiayuguan Pass.
