After that, Ban Chao made great efforts to govern in the imperial court and carried out many reforms, and the people's living standards became better and better. But Ban Chao didn't stop there. He wanted to know what was outside the Han Dynasty, so his curiosity drove him to explore the outside world. After careful consideration, he decided to give up his present job and expand the territory for Dahan. Therefore, at the age of 29, he became the first Dahan envoy to the Western Regions. After he arrived in the western regions, he began to suffer from the cold eyes of the people in the western regions, because the people in the western regions thought that they were all the outposts of the big man and came to conquer them.
But Ban Chao was not defeated by the immediate setbacks. He always remembers the imperial court and the Great Han Dynasty. After he had enough communication with the local people, the local people gradually accepted him. He found that the horses in the western regions were particularly good, and if they were brought back to Dahan for breeding, the fighting capacity of Dahan's army would be further improved. With these horses, the possibility of defeating the Huns has increased a little.
But it is very difficult to bring the horse back to the Great Han Dynasty, because it is not only necessary to bring the horse back, but also to establish various supply stations along the way. It took him five years to set up many observation points on the road from the Western Regions to the Han Dynasty to provide supplies, thus forming a commercial route. Finally, the Han dynasty was able to trade with western countries, which enhanced the national strength of the Han dynasty and defeated the Xiongnu.
