It was very difficult to build such a wall in the ancient days without any modern machines. The construction of the Great Wall was mainly done by hand. The large stones, earth, wood and bricks were carried on human’s back or lifted by the bar. Simple machines were also used, such as varied handcarts, crowbars and wheels. Horses and Donkeys were also used to transport the materials.
Thousands of men died and were buried under the wall they built. The Great Wall was made not only of stone and earth, but of the flesh and blood of millions of men.
