its impossible to know he did not keep records of the people he had killed during the construction and basically his supervisor killed anyone who were slighty out of line and many people simply die from exhaustion

i agree with Mr. Alex. Problably the people who recorded the things going on were either killed or not able to count all the peopole who died. But i think i learned that Billoins died or even more. history states that the dead peoples' bodies were used in making the Great Wall of China. Gross!!
