Zhang Qian was an outstanding diplomat, traveler, explorer and pioneer of the Silk Road in Han Dynasty in China. My hometown is Wang Bo Village, 2 kilometers south of Chenggu County, Hanzhong City, Shaanxi Province. Zhang Qian is full of pioneering and adventurous spirit. In the second year of the Western Han Dynasty, under the orders of Emperor Wu of the Han Dynasty, more than 100 people were sent to the Western Regions, which opened up the north-south road from the Han Dynasty to the Western Regions, the famous "Silk Road".
Zhang Qian's Personality Achievement
Zhang Qian sent two missions to the Western Regions, which communicated the trade relations between China and West Asia and Europe, and opened up the famous "Silk Road" in history. Zhang Qian's second mission to the Western Regions brought the envoys of Wusunguo, and Wusunguo and the Western Han Dynasty started friendly exchanges on the basis of equality. The following year, Zhang Qian's deputy envoy to Wusun Kingdom also returned to Han with envoys from the western countries, and Han and the western countries formally started equal and friendly exchanges.
Zhang Qian's trip to the Western Regions brought him into contact with the customs of various countries in the Western Regions. It was the Han dynasty that began to understand the countries in the western regions and established friendly relations between the Han dynasty and the western regions, which laid the foundation for the Western Han government to establish the western regions as the capital of the western regions and formally put the western regions under the jurisdiction of the Western Han government.
