Zhang Qian was an early traveler. He was probably the first man to bring back good information about the
central Asian lands to China.
In 138 BC, Han Wudi sent Zhang Qian to the Yue-chi people to ask for their help against the Xiongnu.
Unfortunately, on the way to West Regions, he was caught by the Xiongnu people. Zhang had to stay with them
for about 10 years before he got away. When Zhang at last reached the Yue-chi in Northern India, he was
disappointed to find that they didn't want to fight against the Xiongnu people.
On his return journey (旅程), Zhang Qian and his men were again caught. It was not until 125 BC that they
returned to China. Although Zhang didn't finish his job he learned a lot about the places, people, customs and
cultures of the 36 kingdoms (王国) of Western Regions.
Han Wudi then sent Zhang to the west again. Zhang's journey to the west helped with international trade,
especially in silk, between China and the West.
