A road is a bridge between two places. The Silk Road has been a bridge between East and West for more than 2,000 years.

But did you know that the Silk Road is not a single route? It is actually a series of trade and cultural transmission（传送）routes. It started to take shape during the Western Han Dynasty. The trade route started from the city of Xi'an in Shaanxi Province and ended in eastern Europe, near today’s Turkey and the Mediterranean Sea（地中海）. The Silk Road was about 6,500 kilometers long. It went across one-fourth of the planet.

The Silk Road got its name because Chinese silk used to be carried along this road. In addition to silk, jade （玉）, tea and iron also went west to Rome. From the West came glass, gems（宝石）, and foods like carrots and sesame.

The Silk Road was very important to both China and the rest of the world. In addition trade, knowledge about science, arts and literature, as well as craftsmanship and technology, was shared across the Silk Road. In this way, languages and cultures developed and influenced each other.

Today, various historical sites along the Silk Road are popular travel destinations, such as the Terracotta Warriors（兵马俑）in Xi’an and Mogao Grottoes（莫高窟） in Dunhuang, Gansu .A new train line, the New Orient Express, is running from Beijing across the Silk Road.
