Set in the Han Dynasty: a princess's handmaid sent to marry a foreign ruler x the Great General of Wusun
There was a maiden by the Han River, but she was impossible to win.
Note: This is not that Han. The "Han" in the Book of Songs refers to the Han River, while the "Han" in the title refers to the Han Dynasty.
Theme: Braving a thousand miles alone on a mission, recording one's achievements in the sands.
