You know about Zhang Qian (200–114 B.C.)????
In the second century B.C., the Chinese weren’t too sure of what lay west of them. So the Han government commissioned its envoy, Zhang Qian, to locate Central Asian kingdoms and open up new markets for Chinese exports. Qian made it as far as Bactria (Afghanistan) where he encountered the remnants of a fascinating culture that had been forced south into India by nomads. The Greco-Bactrians were Hellenic colonists who settled in the area following Alexander the Great’s conquests. They brought grapevine cultivation, European horses, and traditionally proficient artists to the area - which Qian reported to the Han court.
