Leaving Everything Behind

During the Qin dynasty of Shi Huangi, china was turbulent. Shi Huangi was a tyrant. He killed the people who disobeyed him, and the book that he thought was useless.He called tons of tons of workers to work for his construction, without paying money (cause he was the emperor). The most splendid and famous building that he called the workers to build is the Great Wall. Someone said that if you look at the earth from space, the most apparant construction will be the Great Wall. From that, we can understand how enormous the Great Wall is. Shi Huangi built the Great Wall, because he needed it to help him defend the Huns in the north. Most workers of the Great Wall were the civilians. They were called by the soldiers, and they have to go. They couldn't stay with their family, or he and his family would be all killed. As they were called up to work on the Great Wall, they had a very big chance of wouldn't see them any more. Even though you see them, it will probably be about 30 or 40 years after. You would have to work in a big summer day, you couldn't have any water, and you were not allow to rest. If you are lazy, the soldier would whip you. A lot of workers of the Great Wall were died while they were working, cause they were exhausted. They have never seen their family again after they got called up to build the Great Wall. 
The workers and the slaves have experienced the similiar experience. But there were some little differences between them. Slaves got some choice, even though is very slight. The workers got exatcly no choice. Slaves were easier to run away, but the workers were impossible to run away, because the soldiers were right next behind them
