This is a magnificent epic of the Han Dynasty's exploration and operation of the Western Regions over four centuries. Based on historical materials, it vividly narrates the struggles, battles, exchanges, and integration with the Xiongnu and the Western Regions of the Han Dynasty in a chronological order. Starting from Zhang Qian's diplomatic mission to the Western Regions, it explores Emperor Wu of Han’s territorial expansion, and the Silk Road’s role in facilitating trade between the Han Dynasty and the Western Regions and promoting economic development and ethnic exchange. The author takes readers into that legendary era through vivid language and detailed descriptions. The thousands of years of humanity are a history of cultural exchange and integration. While the once powerful Xiongnu have disappeared, the tolerant and inclusive Chinese nation still stands amongst the world's nations for thousands of years.
