The Qin emperor unified the six kingdoms of China into one and still wanted to protect China from the barbarians and tribes up in the north. So he decided to employ people to build a wall along the border but he died before it was finished and it took three dynasties to finish. the Great Wall of China is like a big dragon, it goes up and down across grasslands, deserts, plateaus and mountains. It stretches over a total of four thousand one hundred and sixty three miles going from east to west of China. It was said that Great wall of China is made up of stone, brick, soil, sand , wood and human bones. The first emperor who was known to be a tyrant ( dictator ) forced thousands of men from 13 - 70 years old to build his wall. It was said a person who got enlisted for the service had to work until he died and when he died his body was buried within the wall.
