In August 1937, according to the agreement reached by the Kuomintang and the Communist Party, more than 40,000 Chinese Workers' and Peasants' Red Army troops were reorganized into the Eighth Route Army of the National Revolutionary Army, with jurisdiction over the 115th Division, the 120th Division, and the 129th Division, and they immediately went to the front line of the Anti-Japanese War. The 120th Division, composed of the Second Red Front Army, the 27th Army, the 28th Army, the First and Second Independent Divisions of the Northern Shaanxi Red Army, and the Headquarters Special Agent Regiment, under the leadership of He Long and Guan Xiangying, won a great victory in the Anti-Japanese War in northwestern Shanxi. With epic frankness and enthusiasm, this book reproduces the most realistic and vivid historical pictures of the 120th Division during the Anti-Japanese War.
