The terra-cotta warriors is at Lintong which is half an hour  from Xi’an by bus. The height of the terra-cotta warriors varies from 1.78m, the shortest, to 1.97m, the tallest. They look healthy and strong and have different facial expressions. Probably they were sculpted by craftsmen according to real soldiers of the Qin dynasty. They organically combined the skills of round engraving, bas-relief and linear engraving, and utilized the six traditional folk crafts of sculpturing, such as hand-moulding, sticking, cutting, painting and so on. The clay models were then put in kilns, baked and colour-painted. As the terra-cotta figures have been burnt and have gone through the natural process of decay, we can’t see their original gorgeous colours. However, most of the terra-cotta figures bear the trace of the original colours, and few of them are still as bright as new. They are found to be painted by mineral dyestuffs of vermilion, bright red, pink dark green, powder green, purple, blue, orange, black and white colours.
