The Great Wall of China

Hello, I am Chin Wan, an engineer for the great country Zhong guo (China). We have almost completed one of the most ambitious projects in the known world. After years of work, we have created a barrier between us civilized people and the barbarians to the north. It actually began a long time ago, when several independent dynasties built several smaller walls, which were eventually connected into one wall over 3,100 miles around 214 B.C.E. It took us over 300,000 slaves to do this. Watchtowers were also built 2 bow shots away from each other along the wall. Finally, it is almost done. It will last thousands of years, and show the greatness of China to the entire world.
