Yu Fan (, , ; 164–233), courtesy name Zhongxiang, was a Chinese essayist, politician, and writer of the state of Eastern Wu during the Three Kingdoms period of China. Initially a minor officer under Wang Lang, the Administrator of Kuaiji Commandery, Yu Fan later served under the warlord Sun Ce, who conquered the territories in the Jiangdong (or Wu) region in a series of campaigns from 194 to 199. Sun Ce regarded him highly and once enlisted his help in persuading Hua Xin, another commandery administrator, to surrender. After Sun Ce's death, Yu Fan continued serving under Sun Quan, Sun Ce's younger brother and successor, as a Cavalry Commandant. Sun Quan confined him for some time due to his rude and disrespectful behaviour, but released him in 219 and allowed him to accompany the general Lü Meng to attack Jing Province. During the Jing Province campaign, Yu Fan warned Lü Meng about a possible ambush when Lü Meng was celebrating a minor victory, and was proven right later. 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. Historical sources on Yu Fan's life The authoritative historical source on Yu Fan's life is the Records of the Three Kingdoms (Sanguozhi), written by Chen Shou in the third century. In the fifth century, Pei Songzhi annotated the Sanguozhi by incorporating information from other sources to Chen Shou's original work and adding his personal commentary.
