The decision to link the Long Wall was to keep the bands of barbarian tribesmen out from invading the North so China would not be taken over by them.
The Long Wall is made of various materials in various places. For the mountain regions, the wall was made of stones and gravel. For open plains, clay. The North-eastern woodlands part of the wall was made of planks made from pine, fir and oak trees. While part of the wall that ran through the Gobi Desert was made of sand, pebbles and tamarisk twigs. The Wall, which runs for almost nearly 2,000 miles, was linked and made by about 1 million people, including various kings and people from all over China. They were all housed, clothed and fed.
The making of the Long Wall has helped in two ways: bad and good. Good, because it kept China safe from getting invaded by barbarians and whoever wanted to try to take over China. The way it was bad, about four-hundred thousand people died from exhaustion or starvation and some were killed for sleeping on the job. People who tried to run away were hunted down, and if they were found they were beaten or executed by overseers as a warning to the other workers so they would not do the same.
