Lu Su
Lu Su, an adviser to the Jiangdong warlord Sun Quan, was originally on a mission to offer condolences for Liu Biao's death. By the time he reached Jing Province, however, Liu Cong had already surrendered and Liu Bei had fled south. Lu Su went to see Liu Bei at Changban and, after Liu Bei's defeat, followed him to Xiakou. There he asked where Liu Bei was heading after, and Liu Bei replied that he plans to take refuge under Wu Ju (), an old friend, in the distant Cangwu Commandery (east of present-day Guangxi). To this, Lu Su dissuaded Liu Bei from joining Wu Ju, saying Wu Ju was only an ordinary fellow who would not be independent for long; and persuaded Liu Bei to form an alliance with his lord Sun Quan against Cao Cao. Liu Bei was pleased at this suggestion, and sent Zhuge Liang to follow Lu Su back to meet Sun Quan and secure the alliance.
