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. However, it is still one of the most appealing attractions all around the world owing to its architectural grandeur and historical significance.

The construction of the Great Wall began between the 7th and 8th centuries B.C. when the warring states built defensive walls to ward off enemies from the north. It was only a regional project then. Until the Qin Dynasty, the separate walls were joint together and consequently it stretched from east to west for about 5000 thousand kilometers and served to keep nomadic tribes out. The Wall was further extended and strengthened in the succeeding dynasties. Especially during the Ming dynasty when the northern nomadic ethnic groups became very powerful, the Ming rulers had the Wall renovated 18 times. As a result, not the remains from the Qin dynasty were restored, but some 1000 kilometers were constructed to a full length of 6,700 kilometers.
