Due to different geographical trends, the land Silk Road can be divided into "Northern Silk Road" and "Southern Silk Road". The geographical landscape of the Silk Road on land is very different. People divide it into grassland forest Silk Road, alpine valley Silk Road and desert oasis Silk Road. Silk is a representative commodity exported along the ancient trade routes in China. As the main commodity in exchange, it is also another name for the Silk Road, such as Fur Road, Jade Road, Jewelry Road and Spice Road.
The Maritime Silk Road exported a large number of porcelain after the Middle Ages, so it was also called the "Porcelain Road". In a word, the Silk Road can be divided into broad sense and narrow sense. The Silk Road in a broad sense is the floorboard of the ancient trade routes between China and the West. In a narrow sense, the Silk Road only refers to the Silk Road in the desert oasis during the Han and Tang Dynasties.
