The Terracotta Army is one of the most iconic attractions in Xi'an. It is a collection of life-sized statues of soldiers, horses, and chariots that were buried with the first emperor of China, Qin Shi Huang. The statues were discovered in 1974 and have since become a UNESCO World Heritage site. Visiting the Terracotta Army is like stepping back in time and witnessing the grandeur of ancient China.
