A subprovincial city on the Guanzhong Plain, the city is the third most populous city in Western China, after Chongqing and Chengdu, as well as the most populous city in Northwest China.

Chang'anChang'an (AUDzh-Changan.oggchang2.an1; ) is the traditional name of Xi'an. The site has been inhabited since Neolithic times, during which the Yangshao culture was established in Banpo, in what is now the city's suburbs. Furthermore, in the northern vicinity of modern Xi'an, Qin Shi Huang of the Qin dynasty, China's first emperor, held his imperial court and constructed his massive mausoleum guarded by the Terracotta Army. From its capital at Xianyang, the Qin dynasty ruled a larger area than either of the preceding dynasties.
Spring and Autumn periodThe Spring and Autumn period was a period in Chinese history from approximately 770 to 481 BCE (or later) which corresponds roughly to the first half of the Eastern Zhou period. The period's name derives from the Spring and Autumn Annals, a chronicle of the state of Lu between 722 and 481 BCE, which tradition associates with Confucius (551–479 BCE). During this period, royal control over the various local polities eroded as regional lords increasingly exercised political autonomy, negotiating their own alliances, waging wars amongst themselves, up to defying the king's court in Luoyi.
Emperor Taizong of Tang'Emperor Taizong of Tang (28 January 598 - 10 July 649), previously Prince of Qin, personal name Li Shimin', was the second emperor of the Tang dynasty of China, ruling from 626 to 649. He is traditionally regarded as a co-founder of the dynasty for his role in encouraging Li Yuan, his father, to rebel against the Sui dynasty at Jinyang in 617. Taizong subsequently played a pivotal role in defeating several of the dynasty's most dangerous opponents and solidifying its rule over China.
