Yu Fan
Yu Fan was known for being very candid, outspoken and direct. As such, he offended Sun Quan several times – including instances when he was drunk – and did not get along well with many of his colleagues. He also mocked and belittled two enemy officers, Yu Jin and Mi Fang, who surrendered to Sun Quan. Sometime in the 220s, Sun Quan could no longer tolerate Yu Fan's disrespectful attitude and banished him to the remote Jiao Province in southern China. Yu Fan lived in exile for over a decade, during which he spent his time lecturing and writing. Even while living in exile, he was still concerned about state affairs, and he once wrote to Sun Quan to advise him against sending a fleet across the sea to attack the warlord Gongsun Yuan in northeastern China, but was ignored. When the fleet sustained heavy losses due to storms, Sun Quan regretted his decision and summoned Yu Fan back, but Yu Fan had already died by then.
