Question
What do you know about the "Great wall of China".
Solution
Throughout its history, China suffered extensively from nomad intrusion and different regimes - even as early as the eighth century BCE - built fortifications to protect their subjects.
Starting from the third century BCE, these fortifications started to be integrated into a common defensive outwork known today as the "Great Wall of China" a dramatic visual testament to the disturbance and fear perpetrated by nomadic raids on the agrarian societies of north China.
