In the spring of 1974, when villagers were digging a well near Xiangyang, Shanxi Province, they came across unusual pottery fragments. Some resembled human figures, while others looked like animals. Word of the chance findings alerted archeologists, who soon uncovered on the site a huge army of terracotta warriors and horses, which had been interred with the remains of the First Emperor more than 2000 years ago. Altogether, four pits housing thousands of terracotta warriors have been unearthed, numbered according to the time sequence of their discovery. Pit No.1, with an area of more than 14000 square meters, is the largest. It is home to an entire battle formation of life-size soldiers and horses. The front echelon consists of 210 soldiers standing in three rows, with the commander in the front. About 6000 soldiers make up the main body of the formation. They stand in 38 columns, some ad long as 180 meters. All of them sport suits of armor and hold bronze weapons. On wither side of the central echelon is a row of 180 soldiers, as flanks of the formation. At the back, more than 100 warriors stand, probably part of the rear guard. Among drawing a wooden war chariot. As the most imposing of all the battle formations discovered so far, Pit No.1 is most likely a replica of the actual troops during the First Emperor’s lifetime. Pit No.2 and 3 were discovered in the summer of 1976. Pit No.2 has four battle formations, including more than 1300 soldiers and horses, over 80 war chariots, and tens of thousands of bronze weapons. In the eastern section of the pit is a group of archers. At the front are 60 archers standing upright, followed by eight columns totaling 160 archers squatting on one leg and kneeling on the other. To their right is a formation of war chariots arranged in eight rows. In the middle of Pit No.2 is another chariot formation, consisting of 19 chariots, 2 infantrymen and eight horsemen. They are divide into three rows. At the front of each horse stands a soldier, with one hand holding the reins and the other in the pose of pulling a bow. Behind each chariot are three charioteers, followed by a number of foot soldiers. Pit No.3 is located to the west of Pit No.1. In a 凹shape, it is the smallest of all the pits, with only 68 warriors inside. A war chariot was placed at the front of the entrance. The formation resembles the headquarters of the left, central and right divisions of the entire army, but it was probably not completed. Pit No.4 was discovered much later, covering an area of about 5000 square meters. Located between Pits No.2 and 3, it appears to have been planned to house the central divisions, but was filled up without any warriors or horses.
