Xi'an, the political, economic and cultural center of the Northwest China, has a long history and was well-known both at home and abroad early in Tang Dynasty. With the development of travel industry, Xi'an is now a world-famous tourist city, a treasure house of cultural relics. The remains of lost civilizations furnish evidence of every major epoch in China's half a million history. Xi'an’s Terracotta Warriors and Horses from the tomb of China's First Emperor, is one of the wonders of the world. It was also the starting point of the famous Silk Road. Moving around this old city is like going through thousands of years back in time.
