In 1944 during the Sino-Japanese War, the Red Army, an armed group of Chinese Communist Party peasants, escorted victims of the Sino-Japanese War on stretchers, carried by several people along mountainous mountain roads. The Red Army, a Communist Party armed group of peasants, was described by Zhou Enlai as "when fish live in water, the Red Army lives among the people. The Red Army's guerrilla militia stuffed powder and gravel into hollow tree trunks tied with telephone wires taken from the Japanese army. Japanese troops intercept an invading Japanese army in a village in northern China.
The Red Army, an armed group of peasants in 1927, joined the Communist forces in 1929 to form the Labor-Nong Red Army. The Red Army was suppressed by the Kuomintang Army and attacked by the Japanese Army, and made a long march from Ruijin to Yan'an, escaping for about 25,000 miles. 30,000 members of the Red Army, the Chinese Communist Party's army, were incorporated into the National Revolutionary Army on August 22, 1937, as the Eighth Road Army of the National Revolutionary Army, and called the Eight Road Army. It was called the Eight Road Army. The Eight Road Army mainly carried out rear disturbance and guerrilla warfare in the areas occupied by the Japanese.
From August 1940, it conducted large-scale guerrilla attacks on railroads and coal mines in North China by the Baekdan War. The Japanese forces were temporarily disorganized, but were quickly wiped out when the Japanese began their full-scale offensive. Resistance to the Japanese forces was met with much abuse and slaughter by the Chinese militias in various areas. Tunnel warfare, mine warfare, and sparrow warfare were launched. Using big knives, shotguns, cannons, mines, gunpowder, etc., the Japanese soldiers became sleepless and delirious. In response to the guerrilla warfare of the Eight Roads Army, the Japanese counterattack became a quagmire with fierce abuses and massacres such as Operation Sanko in full swing. The number of operations by the Eight Roads Army reached about 99,800, and the total number of Japanese troops killed or wounded in battle was about 401,600, and the total number of those killed or wounded in battle was about 312,200, according to the Chinese side. The Eight Route Army gradually took the lead in the Sino-Japanese War and was renamed the People's Liberation Army after the end of the Civil War.
