The great wall was built in the time of the first Emperor. It stretched Along the northern edge of the Chinese Empire. The great walls built to keep the Chinese in ,and the normed trips that raided from the north out. The great wall was mostly by the army. But poor farmers ,and criminals were also forced to work on it .IT was also not easy to build .so many people died building it that it is was called the longest graveyard in the world. Also the great wall of china is one of the largest construction projects ever. The Chinese built walls around their homes and settlements .many hundreds of thousands of Chinese men worked under conditions for great hardship. Their is also the elephants were brought in to help with moving the heaviest loads .But most of the moving is done by humans.
