@Daisy Ryder,
The Silk Road xxtends 4,000 miles (6,437 kilometres), gets its name from the lucrative Chinese silk trade , a series of trade and cultural transmission routes that were central to cultural interaction through regions of the Asian continent connecting the West and East by linking traders, merchants, pilgrims, monks, soldiers, nomads and urban dwellers from China to the Mediterranean Sea during various periods of time. Does that satisfy you?
