Introduction to the Qin Terracotta Warriors and Horses Formation Hall: The Qin Terracotta Warriors and Horses Formation Hall is located in a cave on the east side of Guanlong Pavilion. It is divided into three exhibition halls to display the three types of combat formations of the Qin army. These terracotta warriors and horses are based on the terracotta warriors and horses unearthed near the Mausoleum of Qin Shihuang in Shaanxi. The square array is arranged as it is. The formation is wonderful, hidden in mystery, powerful and vivid, vividly showing the military power of Qin Shihuang to unify the world.
