The Silk Road is a historically trans-Eurasian trade transportation line, which promoted friendly exchanges between Europe, Asia, Africa and China. China is the hometown of silk. In the trade through this route, silk is the most representative commodity exported by China. /kloc-In the second half of the 9th century, German geographer Richthofen called this land transportation route "Silk Road", which has been accepted by Chinese and foreign historians ever since.
After Zhang Qian passed through the western regions, it officially opened the land passage from China to Europe and Africa. This road starts from Chang 'an, the capital of the Han Dynasty, passes through the Hexi Corridor, and then divides into two routes: one starts from Yangguan, passes through Shanshan, goes west along the northern foot of Kunlun Mountain, passes through shache, goes west through Qingji, leaves Dayuejia, goes to rest, goes west through the plough (jiān, now Alexandria, Egypt, annexed by the Roman Empire in 30 BC), or enters the ptomaine from the south of Da Yue. The other one goes out of Yumenguan, passes through the former Cheshi country, goes west along the southern foot of Tianshan Mountain, goes out of Shule, crosses Qingji in the west, crosses Daguan Bay, and reaches Kangju and Chae Yeon (nomadic in the northwest of Kangju in the Western Han Dynasty, that is, the grassland in the North Caspian Sea, and belongs to Kangju in the Eastern Han Dynasty).
The Silk Road in a broad sense refers to the long-distance commercial, trade and cultural exchange routes that have been formed since ancient times and spread all over Eurasia, even including North Africa and East Africa. In addition to the above routes, it also includes the Maritime Silk Road, which was formed in the Southern and Northern Dynasties and played a great role in the late Ming Dynasty, and the Southern Silk Road, which appeared at the same time as the Northwest Silk Road and replaced the Northwest Silk Road as a communication channel on the road at the end of Yuan Dynasty.
