Shi Huang Di, the first emperor of China, united China and its feuding states. There were many small walls along the border to the north. In an attempt to protect China from Mongols, he engaged in a construction project to connect these barrier walls. Its goal was to prevent the barbarians from easily getting into China. Imagine you are a Mongol commander with thousands of troops trying to invade China during the Qin dynasty. You are supposed to invade China from the northern plains, but you have come across the Great Wall of China. Write a three- to four-paragraph letter to your Mongol commander updating him on the existence of the Great Wall and the difficulties it poses to your army.

Your letter should contain the following information:

addressed to Mongol headquarters
date of your letter, your name, and the location of your army
length and height of the Great Wall
difficulties your army will experience trying to get over or around the wall
possible solutions to penetrate the wall
identify what materials the wall was made out of during the time of the Qin
Your letter should be written using complete sentences with proper grammar, spelling, and punctuation.
