What is the connection between the wall and the Xiongnu?

Answer 1

i thi k it is the dirt

Answer 2

sorry i was wrong there here is the real one :

Especially bothersome were the Xiongnu (“shung-nu”), who lived beyond China’s northern border. Like the Qin, the Han decided that one way to deal with the Xiongnu was to keep them out with a wall. At this point, two things need to be made clear: The Great Wall was never one continuous structure. What we call the Great Wall is really a series of walls constructed over a period of 2,500 years.

Answer 3

the connection between them is that how long the wall is , that the Xiongnu could not walk the whole thing , and that it is in possible to get a horse on it

Answer 4

the connection between them is the dirt and that the wall was to long to walk , and is impossible to get a horse on so they didn't have to worry!
