隴海線
Li Hanhun played notable roles at several junctures in the conflict with Japan. As the Sino-Japanese War was brewing in 1936 and factions within the Kuomintang were in power struggles verging on civil war, Li gave up his commission with the leader of one faction (Chen Jitang 陈济棠), while issuing a universal call-out to all Chinese forces to unite under the leadership of Chiang Kai Shek in resistance against Japan invasion. In 1938, as commander of the 64th Army in the Battle of Lanfeng, he defeated General Kenjii Doihara in Luowangzhai (罗王砦), a depot town on the Longhai Railway where Doihara headquartered his main forces; Doihara had been the principal commander of Japanese forces in China and had been engaging in efforts to control China’s major railroad systems.
