Su Wu
3 min readMission to Xiongnu
Su Wu（140-60 BC）was a diplomat and statesman during China’s Han Dynasty，wel1-known in Chinese history for his faithfulness to his mission and his empire.
In 100 BC，there was a short-lived detente between long-term adversaries Han and Xiongnu.One year earlier，in 101 BC，there had been a new chanyu who came into power in Xiongnu-Chanyu Qiedihou，who had expressed interest in peace with Han and who，as a goodwill gesture，had allowed some Han diplomats who had been detained by Xiongnu to return to Han，along with gifts from the chanyu.
In response，in 100 BC，Emperor Wu commissioned Su，then the deputy commander of the imperial guards，to serve as an ambassador to Xiongnu.His deputy was fellow deputy commander Zhang Sheng，and the third in command was Chang Hui.However，once they arrived at the Xiongnu chanyu’s headquarters，Chanyu Qiedihou was far more arrogant than expected，which angered Zhang.In response，Zhang plotted with two Xiongnu officials，the Prince of Gou and Yu Chang，to assassinate Chanyu Qiedihou’s half-Chinese advisor Wei Li and kidnap the chanyu’s mother.
The Prince of Gou and Yu Chang carried out their plot while the chanyu was away on a hunt，but someone alerted the chanyu，who quickly returned and killed the Prince of Gou in battle and captured Yu.Yu admitted to plotting with Zhang.Zhang，alarmed，informed Su，who had been unaware of Zhang’s plot.Aware that the chanyu was planning on forcing him to surrender to Xiongnu，Su tried to preserve his dignity by committing suicide with his sword.Chanyu Qiedihou，impressed with Su’s heroism，sent messengers to care for Su’s recovery，while putting Zhang and Chang under arrest.
Life in Exile
Unable to force Su to surrender，Chanyu Qiedihou decided to try to torture him by starvation，and so put him in a cellar without food and drink.However，for several days，Su survived by consuming wool from his coat and the snow that fel1into the cellar.The chanyu was further surprised and thought that the gods were protecting him.The chanyu then exiled him to Lake Baikal and ordered him to tend a flock of rams-telling him that he would be allowed to go home when the rams would produce milk.
During exile，Su often lacked food，as the food supplies coming from the Xiongnuheadquarters were not arriving steadily.He often had to resort to eating grass roots and wild rodents.Regardless of the difficulties，however，Su always held ontothe imperial staff，and he used it as the shepherd’s rod-that the decorative hairs on the staff eventually all fell off.
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.
Return to Han
In 81 BC，Han was again in a detente with Xiongnu，when Han ambassadors inquiredof Su’s fate.The Xiongnu government claimed that Su had long died.However，Su’s old assistant Zhang（Zhang became surrendered）secretly informed the ambassadors of Su’s exile，and the ambassadors，under Zhang’s suggestion，told then-Chanyu Huyandi that Emperor Zhao had killed a migratory bird while hunting，and that a letter from Su seeking help was found on the bird’s foot.Surprised，Chanyu Huyandi admittedthat Su was in fact still alive，and recalled him and allowed him to go home.In all，he was in exile for 19 years.
Once Su returned to Han，he was given the position of Director of Colonization，a high-ranking official post.He remained in that post at least until the early years of Emperor Xuan’s reign-late 70s BC.
Impact on Chinese History
Su was often regarded as the epitome of faithful service in light of great oddsand trials.His story was often invoked when acts of great faith or courage were performed by officials.His story，as undetailed as it was in actual history，often became subjects of drama，poetry，and songs throughout Chinese history.
