Li Hai-ching, or Li Hai-Tsing (died 1930s), was the leader of about 10,000 Anti-Japanese guerrilla troops in the south of Kirin, now Heilongjiang province, resisting the pacification of Manchukuo. They called themselves Anti-Japanese Army For The Salvation Of The Country and were described as being equipped with light artillery and numerous machine guns. Li established his headquarters at Fuyu and were in control of the territory there and southward as far as Nungan.
On March 29, 1932 his forces defeated regular troops of the Manchukuoan Governor Xi Qia outside the town of Nungan, only 35 miles from the Manchukuoan capital of Changchun. Nungan was soon reported on the verge of surrender. Small Japanese detachments sent from Changchun radioed for help, after suffering heavy casualties in the fighting. Japanese forces from the east at Yao-men, tried to fight their way through to Nungan with the support of bombers but the defenders radio ceased broadcasting, Li's forces having captured the town.
In another action in late April, 65 miles south of Harbin on the Chinese Eastern Railway, 3,000 Chinese soldiers under General Li Hai-tsing, ripped up the railway tracks and tore down telegraph wires. They then waited until a train from Harbin arrived, looted it and dispersed before the arrival of Japanese troops that were rushed to scene.
In May 1932 the Japanese Li Hai-ching Subjugation Operation defeated and dispersed Li's army. Reformed again in October his guerrilla force, reduced to 3,000 men again tried to attack the Manchukuoan and Japanese forces in southern Heilongjiang province. They were defeated and were forced to retreat into Jehol.
