Lu Su

Lu Su (172–217), courtesy name Zijing, was a Chinese military general and politician serving under the warlord Sun Quan during the late Eastern Han dynasty. In the year 200, when Sun Quan had just taken over the reins of power, his adviser Zhou Yu recommended Lu Su as a talent to Sun Quan. As one of Sun Quan's most important advisers in the warlord's early career, Lu Su is best known for making some significant contributions. Firstly, in 200 he drafted a long-term strategy for Sun Quan's power bloc to emerge as one of three major contending powers in China – a plan similar to Zhuge Liang's Longzhong Plan, which was proposed about seven years later. Secondly, before the Battle of Red Cliffs in late 208, he was the first person to persuade Sun Quan to ally with Liu Bei against Cao Cao. Thirdly, he succeeded Zhou Yu as the frontline commander of Sun Quan's forces in 210 after Zhou's death and maintained the Sun–Liu alliance. Fourthly, in 215, he represented Sun Quan at the negotiations with Liu Bei's general Guan Yu during the Sun–Liu territorial dispute over Jing Province. Provided by Wikipedia
