Zhang Qian was detained for more than ten years, married to him, and had children. However, Zhang Qian kept the talisman of the Han Dynasty envoy and did not lose it.
The festival held by the envoys of the Han Dynasty was awarded by the emperor to show that the holder was the emperor's representative; secondly, for the envoys, the festival he held was a symbol of the emperor and the country. Protecting it also reflects his loyalty to his country. Therefore, Zhang Qian never left Hanjie in the midst of hardships and dangers, showing his utter loyalty to the country.
