The Hundred Regiments Offensive 2015 one on netflix

The Japanese has invaded far into china, defeating the Kuomintang (KMT) soldiers many times and pushing them back into Central China. There was a general sentiment among anti-Japanese resistance forces that the Communist Party of China (CCP) was not contributing enough to the war, and that they were only interested in expanding their power. As a result, the CCP planned a major offensive against the Japanese, consisting of 105 regiments, called the Hundred Regiments Offensive.
