We didn't get to see these because they are in Xian, which was not included in our trip. This is one of the reasons I want to go back to China. Shortly before our trip we saw a Discovery Channel show on the First Emperor of China, Qinshihuangdi. So far archaeologists have found 8,000 terracotta warriors buried in front of the Emperor's tomb. In addition to burying these warriors, he also buried about 700,000 people in the tomb. These were the workers who built it and childless concubines (not sure why). He didn't want anyone to find it. Pretty effective way to keep the tomb hidden. The warriors were mass produced through a series of processes that began with the molding of solid legs. Attaching a hollow head and body on the solid legs enabled the warrior to stand upright and not topple over. All of this was done 250 years before the birth of Christ.
