Terracotta Army: Guardians of the First Emperor’s tomb march to Cincinnati

Chinese farmers were digging a well in a rural area of Xi'an, China in 1974 when they came across pieces of what appeared to be ceramic armor. No one knew what it was at first.  Turns out, the farmers had discovered more than 8,000 clay soldiers standing guard at the tomb of Emperor Qin Shihuang. It would become one of the greatest archaeological discoveries of the 20th century.  Known today as the Terracotta Army, the soldiers are part of Emperor Qin's intricate necropolis that encompasses more than 20 square miles.
