参考译文
The Silk Road
The "Silk Road" refers to the ancient commercial trade routes starting from China and connecting Asia, Africa and Europe. In a broad sense, it is divided into the silk road on the land and silk road on the sea. The "land silk road" opened between the 2nd century BC and the 1st century AD and remained in use until the 16th century. It started from Chang’an in the Western Han Dynasty (or Luoyang in the Eastern Han Dynasty) to Dunhuang via the Gansu Corridor. The "silk road on the sea" formed in the Qin and Han Dynasty.
