What is the significance of the Silk Road?

Since opened by Zhang Qian, this channel has become the main channel of foreign communication in successive dynasties. Chinese lacquerware, gunpowder, compass, porcelain, papermaking, well drilling, smelting and other technologies began to spread to the west, while grapes, pomegranates, walnuts, spices, pepper, glass, ivory and lions were spread to the east. The "Land Silk Road" was an important channel for the spread of ancient Chinese civilization to the West, and a bridge for economic and cultural exchanges between China and the West.
