Their weights are also different. The lightest being 110 kilograms and the heaviest 300 kilograms. In order to keep the balance of the warriors, the workmen in the Qin dynasty added a pedal to each warrior under his foot, so that the warrior would stand more firmly. The foot pedals were made in molds. The feet, shoes, legs and armours of the warriors were made by hand.
Some legs are hollow, some are solid.
The bodies of the warriors are all made separately and join the models together to complete the work. Arms also have two kinds, hollow and solid forms. The hollow arms are made with the above-mentioned method, the solid ones are made separately. In December 1980, two sets of large painted bronze chariots and horses were unearthed 20 metres west of the tomb of the first Emperor of the Qin Dynasty. They were listed as No.1 and No.2 respectively according to their discovery.
