Terra cotta Army is the Terra Cotta Warriors and Horses of Qin Shi Huang, the First Emperor of China. The terracotta figures, dating from 210 BC, were discovered in 1974 by some local farmers near Xi'an, Shaanxi province, China near the Mausoleum of the First Qin Emperor. The figures vary in height (183–195 cm - 6 ft–6 ft 5in), according to their roles, with the tallest being the generals. The figures include warriors, chariots, horses, officials, acrobats, strongmen, and musicians. Current estimates are that in the three pits containing the Terracotta Army that there were over 8,000 soldiers, 130 chariots with 520 horses and 150 cavalry horses, the majority of which are still buried in the pits. The Terracotta Army Museum lies 1.5 km east of The Tomb of Qin Shihuang, known as the First Emperor, who unified China 2200 years ago. Emperor Qin, from whom China gets its name, ordered the creation of this model army. Every figure differs from those around in facial features and expression, clothing, hairstyle, and gestures. The horsemen, the longbow bearers, the archers and the senior officers and generals were positioned in strict accordance with the ancient directives on the Art of War. Many of the figures originally held real weapons of the time, such as bronze swords, longbows, arrows, spears, dagger-axes and other long-shafted weapons. Surface treatment of the weapons made them resistant to rust and corrosion so that after being buried for over 2000 years they were still sharp. The Terracotta Army figures supply abundant and detailed artifacts for the study of the military, cultural and economic history of that period. The Terracotta Army figures excavation was regarded as one of the greatest discoveries of the 20th century. In December 1987, UNESCO selected the Tomb of the First Emperor (including the Terracotta Army Vaults) as a World Cultural Heritage Site. Standing in the vaults, you would be amazed by such a grand ancient army formation, which would transport you back to the ancient warring states period. The tomb is a treasury for the Chinese people and for the whole world as well. The main tomb has still to be excavated - partly because archaeologists are still uncertain of its exact location. Often Emperors amassed huge burial mounds simply to divert robbers' attention from the true site of their tomb. So the artificial mound that today marks the Emperor's tomb does not necessarily indicate the location of its wondrous central chamber. However, because high mercury levels have recently been reported nearby, archaeologists think they may, at last, have discovered it. The Terracotta Warriors, that you will see today, form just one of the many barriers which the ruthless Emperor employed to protect his tomb for eternity.
