No 2 Xi'an

Xi'an, located in northwest China, is known all over the world as the home to the Terracotta Army and the eastern terminus of the Silk Road.

Xi'an also rivals Athens, Cairo and Rome as one of the four ancient capitals in the world as the city has a history of more than 3,100 years, in which more than 1,100 years was as the capital city for 13 dynasties (there are still some debates over the number of dynasties which use Xi'an as their capital).
