八路军
The New Fourth Army () was a unit of the National Revolutionary Army of the Republic of China established in 1937. In contrast to most of the National Revolutionary Army, it was controlled by the Communist Party of China and not by the ruling Kuomintang. The New Fourth Army and the Eighth Route Army were the two main communist forces from 1938. The New Fourth Army was active south of the Yangtze River (Chang Jiang), while the Eighth Route Army was based in Yan'an in the northwest.
