how did china get so many things to make the great wall of china? and how did they get transported there?

How ancient Chinese people moved big materials up to the mountains in the Great Wall Construction? People in ancient China used several ways to solve the problem. Many people(They are soldiers, peasants and prisoners)died from the work. People burdened the weight on their shoulders, and backs, passing the materials from the foot of the mountain right to the very top. they use wheelbarrows to roll timbers and crowbars to the top. Some of the animals helped alot in building the Great Wall in the mountain area. The material to build the Great Wall is different in different areas.At the beginning, the Great Wall was mainly made of earth, stones and wood. Due to the large amount of materials required constructing the Great Wall, the builders tried to use local resources. When they built over the mountain ranges. Some of they supplys they got from workshops and stone ponds. when there was no wood they got it from places around them.
