As the main reason why most tourists visit Xi'an in the first place, no holiday in this ancient city would be complete without touring the heritage site that made it famous. Hailed as one of the biggest archeological discoveries of the century, the tomb of China's first emperor contained thousands of terracotta warriors who were to accompany him into the afterlife as they did when he was ruling China. More than 2000 years old, the archeological site has become a tourist magnet over the years and it's easy to see why when gazing upon these clay figures with facial expressions, weaponry and clothing that distinguish each soldier.
