Duan Xiu traveled to the Western Regions in the sixth year of Guanghe's reign and became the last Han captain in Qiancheng. Facing the few hundred people left in the city, the Kucha army surrounding the city, and his father's dying order to "guard Liangyong", he just silently inspected the two newly made knives. When the envoy from Qiuci once again "persuaded surrender", Duan Xiu drew his Huanshou sword and pointed it to the east - he wanted to lead this group of Han people back to Yumen Pass.
