Caitlin, I should say it was discovered accidentally. In 140BC, Zhangqian was sent to Western Regions by Emperor Wudi of the Han Dynasty. His mission was to persuade Great Yüeh-chin to defeat the Huns with Han Empire. Unfortunately, he was captured by the Huns and confined for 10 years. Finally, he ran away in 129 BC and finally reached Great Yüeh-chin. He stayed there for a year but failed to persuade them. Then he took his way back to his home. In order to avoid the Hun, he took a path in the south. Unfortunately, he was caught by the Huns again. In 126 BC, he escaped and went back. His unbelievable adventure made him know more about the Western Regions and finally open a trade route called Silk Road.
