Xi'an, the capital of Shaanxi Province, is located in the heart of the Guanzhong Basin, with the Weihe River running along the northern border of the city. It is the largest metropolis in northwestern China. Known as Chang'an in ancient China, Xi'an is a world-renowned ancient capital.

For 1,062 years beginning in the 11th century B.C., Xi'an was the capital of 13 dynasties including the Western Zhou, Qin, Western Han, Eastern Han, Sui, and Tang. The continuous dynastic occupation kept the city beautiful and magnificent. More than two hundred and seventy palaces and temples were built during its heyday, such as the "Three Han Palaces" in the Han dynasty, namely Changle, Weiyang, Jianzhang Palaces, and numerous other palaces and watch towers. The most well known among these is the Tomb of Emperor Qin Shihuang, with the Terra-cotta Warriors and Horses. Xi'an is also the starting point of the ancient Silk Road.
