A road is just like a bridge between two places. The Silk Road has been a bridge between East and West. But the Silk Road is not a single route! It is a series of trade and cultural transmission routes. From the time Zhang Qian opened up the world-famous Silk Road during the Han Dynasty, until the Yuan Dynasty, it enjoyed a history of about l,600 years.
This ancient road begins at Chang'an (now Xi’an), and it reaches Dunhuang, where it divides into three, the Southern Route, Central Route and Northern Route. And then it ends in Eastern Europe, near the Mediterranean Sea(地中海). The Silk Road is about 6,500 kilometers long. It goes across one-fourth of the planet. (83)In fact, there is another trade road which is called the “Silk Road on the Sea” in the southwest of China.
The Silk Road was very important to both China and the rest of the world. Besides trade, knowledge about science, arts and technologies were shared across the Silk Road. The Four Great Inventions of China was introduced to the West and Chinese also knew about the religions of the West. (84)In this way, languages and cultures developed and influenced each other. Today, places along the Silk Road are great places of interest, such as the Terracotta Warriors in Xi'an and Mogao Grottoes in Dunhuang, Gansu.
