Cultural exchanges between China and the West during Ju Lushi's period.

The long traffic between China and the West began in a very early historical period. As the national treasure of China, silk was quite developed in the Yin and Zhou Dynasties and was deeply loved by the surrounding ethnic groups. Grassland nomads who have no fixed abode are scattered outside the Eurasian civilization circle. They act as disseminators of two civilizations and promote cultural exchanges between countries located at the east and west ends of Eurasia. China silk was introduced to the west, first from the Caspian Sea and the Black Sea to the grassland in the northern Mediterranean.

According to historical data, the first head of state of China to visit western countries may be Zhou Muwang, the leader of the Western Zhou Dynasty in 10 century BC. At that time, he set out from the Central Plains, traveled westward to the northwest, arrived at some clans and tribes in Central Asia, and presented silk as a national gift to the countries he visited. This may be the earliest history of silk being introduced to the west.

It was not until the second century BC that Emperor Wu of the Han Dynasty sent Zhang Qian to the Western Regions that the Oasis Silk Road from Xinjiang to West Asia was opened. What people usually call the Silk Road is centuries later than the Grassland Silk Road.

In the eighth century BC, the so-called "Great Migration" movement appeared in Greece, that is, from ancient agriculture to commercial colonization. One of them crossed Heiles and went deep into the whole Black Sea coast. These ancient Greeks often traded with the Scythians on the northern shore of the Black Sea. The Scythians traded grain, wool and slaves, but also resold goods from the Far East. In the famous Homer epic Odyssey, he wrote: "From the threshold to the inner room, there is a soft front edge on the chair." These silks may have been exchanged with the Skettians.
