The difficulties that were faced by Han soldiers sent to the wall was that han soldiers were ordered to work on the wall as well as to protect it. Another thing that they faced was that the han soldiers had heavy fighting against the Xiongnu during much of 2nd century BCE.4.I can use to argue that building the great wall was worth the cost is that the great wall had protected trade along the silk road which brought great advantages to China. 5.I can use this document to explain that building the Great Wall was not worth the cost because families were separated and peasants/soldiers and at the Great Wall people suffered sickness, death and fighting.
