Runners in a relay(接力) race pass a stick in one direction. However, merchants passed silk, gold, fruit, and glass along the Silk Road in more than one direction. They earned their living by traveling the famous Silk Road.

The Silk Road was not a simple trading network. It passed through thousands of citied and towns. It started from eastern China, across Central Asia and the Middle East, and ended in the Mediterranean Sea. It was used from about 200 B, C, to about A, D, 1300, when sea travel offered new routes(路线) , It was sometimes called the world’s longest highway.

Indian merchants traded salt and other valuable goods. Chinese merchants traded paper, which produced an immediate effect on the West. Apples traveled from central Asia to Rome.

Trading along the Silk Road led to world-wide business 2,000 years before the World Wide Web.
