This discovery aroused much interest both at home and abroad

The terra-cotta warriors and horses are arrayed according to the Qin dynasty battle formation, symbolizing the troops keeping vigil beside the mausoleum. This discovery aroused much interest both at home and abroad.
No.1 Pit is 230 meters long from east to west, 62m wide from north to south and 5m deep, covering a total area of 14,260 square meters. There are five sloping entrances on the eastern and western sides of the pit respectively. The pit is divided into eleven corridors by ten earthen partition walls, and the floors are paved with bricks. Thick rafters were placed onto the walls (but now one can only see their remains), which were covered with mats and then fine soil and earth. In the east end are arrayed three lines of terra-cotta warriors, 70 pieces in each, totaling 210 pieces. They are supposed to be the van of the formation. Immediately behind them are 38 columns of infantrymen alternating with war chariots in the corridors, each being 180m long. There is one line of warriors in the left, right and west ends respectively, facing outwards. There are altogether 27 trial trench, it is assumed that more than 6,000 clay warriors and horses could be unearthed from No.1 Pit.
No.3 Pit covers an area of 520m2 with only four horses, one chariot and 68 warriors, supposed to be the command post of the battle formation. Now, visitors can see some clay figures and weapons displayed in the exhibition halls in the museum.
All of the clay warriors in the three pits held real weapons in their hands and face east, showing Emperor Qin Shihuang's strong determination of wiping out the six states and unifying the whole country. 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.   
In December 1980, two teams of large painted bronze chariots and horses were unearthed 20 metres west of the mound of Emperor Qin Shihuang's Mausoleum. These single shaft four-horse chariots each comprises 3,462 spare parts, and has a body with two compartments, one behind the other, and an elliptical umbrella like canopy. The four horses harnessed to the chariot are 65-67 centimeters tall. The restored bronze chariots and horses are exact imitations of true chariot, horse and driver in half life-size.
Terra-cotta Warriors is considered the most marvelous rediscovery in the 20th century.
