which were guarded by Liu Bei's general Guan Yu. He claimed that he was ill and returned to Jianye (建業; present-day Nanjing, Jiangsu) to put Guan Yu off guard. He also managed to persuade Sun Quan to release Yu Fan from confinement and let Yu Fan accompany him, because Yu Fan had medical skills and could help to treat his illness. Later that year, during the invasion of Jing Province, after Lü Meng received the surrender of Mi Fang, the Administrator of Nan Commandery (南郡; around present-day Jiangling County, Hubei), he did not immediately order his forces to occupy the city and instead held celebrations on the beach.

Cao Pi then established the state of Cao
