The Silk Road is not only a vital ancient trade route,but also a bridge linking the cultures of China and the West,through which the Four Great Inventions of China and religious beliefs of the West were introduced into their counterparts.From Zhang Qian opening up the world-famous Silk Road during the Han Dynasty,to the collapse of the Yuan Dynasty,it experienced a history of about 1,600 years.The Silk Road begins at Chang'an,and then by way of Hexi Corridor,it reaches Dunhuang, where it divides into three branches-the Southern Route,Central Route and Northern Route.The three Routes spread all over Xinjiang Uygur Autonomous Region,and extend as far as Pakistan,India and even Rome.
