1. Strengthen the armed forces

Jinggangshan, led by Mao Zedong and Zhu De, brought together the armed forces of the Hunan-Jiangxi border revolution. Jinggangshan has become the meeting point of China's revolutionary armed forces, the foothold of China's revolution and the starting point of China's victory. The main armed forces stationed in Jinggangshan are: ① the autumn harvest uprising troops led by Mao Zedong; (2) Nanchang Uprising led by Zhu De and Chen Yi; (3) Peasant Army Uprising in Southern Hunan; ④ Two local armed forces led by Yuan, Yuan and Yuan in Jinggangshan; (5) local revolutionary armed forces such as riot squads and red guards organized in the counties of the base areas. 1On May 4th, 928, the Fourth Army of the Chinese Red Army of Workers and Peasants ruled over nine regiments in three divisions, with a total of more than 10000 people (after the establishment was cancelled, the Gongsijun was reduced to four main regiments, with a total of more than 6000 people), which was the largest revolutionary armed force directly led by China at that time, with the largest number of soldiers, the deepest influence and the strongest fighting capacity.

2. Preserve, train and train Red Army cadres.

After joining forces in Jinggangshan, a large number of workers, peasants and Red Army officers and men who firmly believed in Marxism-Leninism experienced arduous struggles in Jinggangshan. They have been tempered and honed in the difficult and difficult war years, strengthened their revolutionary beliefs, cultivated their revolutionary will, and improved their practical work ability and the level of fighting against the enemy. In the great Jinggangshan struggle, a large number of outstanding Red Army officers and men have withstood the baptism of blood and fire, gone through hardships and hardships, stood out and forged into a generation of new China's founding fathers. Counting the participants in the Jinggangshan struggle, Zhu De, Peng, Lin Biao, Chen Yi and Luo Ronghuan are five marshals of the China People's Liberation Army, accounting for half of all marshals; Li Yu, Tan Zheng and Huang Kecheng are three generals of the China People's Liberation Army, accounting for one-third of all generals; Deng Hua, Zhu, Li Jukui, Yang Zhicheng, Yang Dezhi, Xiao Ke, Song Renqiong, Song, Zhang Zongxun, Chen Bojun, Zhao Erlu, Huang Yongsheng and Lai Chuanzhu are the PLA 14 generals; , Wang Zifeng, Bi, Yang Meisheng, Li Shouxuan, Xiao Xinhuai, Zhang Lingbin, Zhang Guohua, Ouyang Yi, Zhao Rong, Yao Zhe, Zhou Yucheng,,,, Han Wei, Lion, Tan Furen, Tan Xilin, Tan Guansan, Tan Jiashu and other 20 Chinese People's Liberation Army Lieutenant Generals; Wang Yunlin,, Long Kaifu, Lai, Liu,, Chen Yunzhong, Zeng, Long Gan and Peng Longfei are major generals of China People's Liberation Army 12; Tan Zhenlin, Teng, He Changgong, Chen Zhengren, Jiang Hua, Liu Xing, Li Li, Li Keru, Wu Zhonglian,,, He, He Zizhen, Gao, Huang Da, Ceng Zhi, Peng Ru, Duan Ziying, Xiong Shouqi, Tan Zhengwen and Xiao Ming held important leadership positions at the central and local levels. Jinggangshan joined forces, preserved a large number of political and military cadres of the Red Army, and created a large number of national pillars and national elites.

3. Created a new situation in the revolutionary base areas.

The establishment of Zhu Mao Jinggangshan Association and the Red Fourth Front Army accelerated the momentum of starting a prairie fire in Jinggangshan, promoted the revolutionary struggle in Jinggangshan to continue to develop in depth, and quickly achieved "various military victories in April and July and the development of mass separatism" (Mao Zedong: The Struggle in Jinggangshan). After joining forces with Jinggangshan, the military strength of Jinggangshan revolutionary base area was greatly enhanced. At the end of April, gongsijun won five battles in the first battle, breaking the enemy's second "encirclement and suppression" of Jinggangshan revolutionary base. Gongsijun occupied Yongxin New Town and established the government of workers, peasants and soldiers in Yongxin County. In mid-May, the Red Fourth Front Army won the battle in Caoshiao, occupied Yongxin City for the second time, and broke Jinggangshan's third "encirclement and suppression" of Jiangxi's revolutionary base behind enemy lines. 1On June 23rd, 928, Long Yuan won a total victory, "defeated two sheep in Jiangxi" and broke the enemy's fourth "encirclement and suppression" of Jinggangshan revolutionary base area. Gongsijun immediately occupied Yongxin and Lianhua, and the red separatist areas were widely promoted. At this time, "the separatist areas include Ninggang County, Yongxin County, Lianhua County, a small part of Ji 'an, a small part of Anfu, a part of the northern township of Suichuan and a part of the southeastern township of Lingxian County, hundreds of miles in Fiona Fang" (Yang Kemin: Comprehensive Report on the Situation of the Soviet Area on the Hunan-Jiangxi Border1February 25, 929), covering an area of 7,200 square kilometers. Following the establishment of the governments of workers, peasants and soldiers in Chaling, Suichuan, Ninggang and Yongxin, Jinggangshan joined forces to promote the red area, and the governments of workers, peasants and soldiers in the border areas of Hunan and Jiangxi came into being, and the governments of Lingxian and Lianhua were announced. Under the unified leadership of the government of workers, peasants and soldiers in the border areas of Hunan and Jiangxi, a vigorous agrarian revolutionary movement was launched in the border counties. The border party has grown from scratch, from weak to strong, and the border party organization has been growing. Border local armed forces and mass organizations such as Red Guards, Young Pioneers and children's groups have developed rapidly. Jinggangshan revolutionary base area thus entered its heyday.
