China publishes video series on war against Japan's aggression

This is the 19th part of the series released daily by the State Archives Administration from Aug. 25, as the country marks the 69th anniversary of victory against Japan's aggression.

On November 1939, a Japanese troop attacked and seized Nanning city, currently capital of south China's Guangxi Zhuang Autonomous Region. On Dec. 4 1939, they seized the Kunlunguan, an important gateway and military stronghold about 50 km from Nanning.

On Nov. 18, the Chinese side, under the command of Kuomintang general Bai Chongxi, launched a offensive to take back the Kunlunguan. They succeeded after 13 days of close engagement and fierce fighting with Japanese troops.

About 4,000 Japanese soldiers and several senior officers, including a major general, were killed in the battle, later known as the Kunlunguan Victory.

China has officially set Sept. 3 as Victory Day to mark Japan's surrender on Sept. 2, 1945.
