Andrew Bae Jong Seong - Great Wall of China

The Great Wall of China is a series of fortifications made of stone, brick, tamped earth, wood, and other materials, generally built along an east-to-west line across the historical northern borders of China in part to protect the Chinese Empire or its prototypical states against intrusions by various nomadic groups or military incursions by various warlike peoples or forces.Furthermore, the defensive characteristics of the Great Wall were enhanced by the construction of watch towers, troop barracks, garrison stations, signaling capabilities through the means of smoke or fire, and the fact that the path of the Great Wall also served as a transportation corridor. Although it caused many deaths, the Great Wall of China was still strongly built and it is also served as a historical structure in China. I still cannot believe that it is built by human beings, I learned that no matter how hard the task is, if we can unite as one, motivate each other, the task could be done.
