蔡锷
Schooled under Cai E, Li graduated from the Guilin Military Cadre Training School and in 1916 became a platoon commander in the army of Guangxi warlord Lu Rongting. Li's direct superior was Lin Hu. Lu, the governor of Guangxi, was a former bandit who had ambitions to expand into neighboring provinces, especially Guangdong. For the next few years the warlords of Guangxi and Guangdong were involved in mutually destructive battles, and both occupied portions of each other's territory at various times. Lu and his closest associates were collectively known as the Old Guangxi Clique. During a battle with a rival warlord in Hunan in 1918, Li's bravery earned him a promotion to battalion commander.
