how can I explain the Great Wall was successful in keeping semi-nomadic invaders out, which was the primary concern at the time.
However, the wall did not stop some large scale invasions, and even the nomadic people were able to breach the wall from time to time. to a little kid.
This wall helped a little keep small invaders out because it provided a wall that was difficult to get over. But it wasn’t good enough to stop big invasions because a large amount of people would overwhelm the guards.
