From the second century BC to the end of the fourteenth century AD, a great trade route originated from Chang'an (now Xian) in the east and ended at the Mediterranean in the west, linking China with the Roman Empire. Because silk was the major trade product which traveled on this road, it was named the Silk Road in 1877 by Ferdinand von Richthofen – a well-known German geographer. This ancient route not only circulated goods, but also exchanged the splendid cultures of China, India, Persia, Arabia, Greek and Rome.
