The Silk Road, originated in the 1st century BC, is an international trade route of great historical significance. Because silk occupied a large proportion in the trade of this route, the famous German geographer Ferdinand von Richthofen named it "Silk Road" in 1877.
It is not only an ancient international trade route, but also a splendid cultural bridge connecting China, India, Persia, Greece and Rome. It is through this bridge that China's four great inventions and Western religions were introduced to other countries.
