蘇武
Twice, during exile, the chanyu sent Li Ling, who had surrendered to Xiongnu after being defeated on the battlefield in 99 BC, to visit Su. The first time, Li informed Su that his two brothers had both been accused of crimes and committed suicide; that his mother had died; and that his wife had remarried. He tried to convince Su to surrender, but Su refused. On the second occasion, Li informed him of Emperor Wu's passing, and Su was so despondent that in mourning that he vomited blood. When the Emperor of Han died, Su Wu faced south towards his old homeland of China and wept in utter sadness.
