Chen Yi truthfully reported the problems existing in GongSiJun to Zhou Enlai and others. The evaluation of Liu Angong, a special correspondent of the Central Committee, is to completely copy the Soviet model. He comes to every meeting, speaks when he arrives, and likes criticism, which is endless. After listening to Chen Yi's report, the Politburo decided to set up a committee composed of Li, Chen Yi, and put forward a resolution for discussion. The three-member committee was convened by Zhou Enlai, secretary of the Central Military Commission and minister of military affairs, and was responsible for drafting instructions to the front committee of Gongsijun to resolve the differences within the Party. Zhou Enlai gave this task to Chen Yi. After receiving this task, Chen Yi locked himself in his room and read several reports written by Mao Zedong to the Central Committee, which filled him with thoughts. He truly felt that Mao Zedong's foresight and wisdom on the political line were far ahead of his peers. After repeated and serious thinking and summing-up, Comrade Chen Yi, on behalf of the Central Committee, carefully wrote and drafted the Central Committee's instruction to Gongsijun, namely "Letter in September". The September letter correctly analyzed the current political situation, clearly defined the tasks of the Red Army, pointed out that all incorrect tendencies in the Red Army must be corrected, emphasized the strengthening of the Party's leadership over the Red Army, and clearly wrote down the words that Comrade Mao Zedong would continue to serve as the secretary of the Front Committee.

Chen Yi returned to Shanghang, the headquarters of Gongsijun Front Committee, and called Zhu De and other members of Gongsijun Front Committee for a meeting to convey the spirit of the letter from the Central Committee in September. In September, the messenger Zhu Mao and others untied the knot and unified their thoughts. After a series of rectification, the troops improved their combat effectiveness.

19291On February 28th, the 9th Congress of the Fourth Army of China was held in Shuguang Primary School, Gutian Town, Shanghang, Fujian, which was known as Gutian Conference. The meeting seriously discussed the spirit of the letter from the Central Committee in September. Mao Zedong made a report to the meeting. He first talked about the existence of non-proletarian ideology in the party, and then talked about the problem of pure military view that has existed since the establishment of the Red Army. Finally, he concluded that the Chinese Red Army of Workers and Peasants is an armed group carrying out revolutionary political tasks. This meeting is a great milestone in the history of our party and army. The meeting unanimously adopted the general assembly resolution drafted by Mao Zedong, which clarified the nature, purpose and task of the Red Army, reaffirmed the Party's absolute leadership over the army, and answered and solved a series of major problems in building a new people's army under the leadership of China. The policy of ideological party building and political army building laid a foundation for the formation, development and practice of the idea of encircling cities from rural areas and seizing political power by armed forces. The principle of army building established by Gutian Conference is the crystallization of the collective wisdom of the people of China, represented by Mao Zedong, and it is still the fundamental principle of our party in building the people's army. The resolution of Gutian Conference is a programmatic document for the construction of China and the Red Army.

Since its birth, China has shouldered the historical responsibility of people's liberation and country's prosperity. In the struggle against imperialist powers, bureaucrat-comprador bourgeoisie and feudal landlord class, China * * * once formed a united front with the Kuomintang, launched a vigorous great revolutionary movement, endured the bloody baptism of the Northern Expedition, initially mastered some revolutionary armed forces and made a unique contribution to the Great Revolution. After the failure of the Great Revolution, China * * * profoundly realized the importance of establishing revolutionary armed forces from the lessons of blood. The Nanchang Uprising started the first shot of the people's armed forces against the Kuomintang reactionaries. The Autumn Harvest Uprising publicly carried the banner of China, and carried out the great practice of creating a new people's army that can start a prairie fire.

From the Northern Expedition to the failure of the Great Revolution, from the establishment of the Jinggangshan Revolutionary Base to the Gutian Conference, a generation of pioneers, represented by proletarian revolutionaries such as Mao Zedong, Zhou Enlai and Zhu De, searched up and down in the long history of Xiu Yuan and dared to explore, and finally found the correct way to establish a new type of people's army. A heroic people's army led by our party with the interests of the people as its own responsibility was born. With the continuous development of the people's army, China has embarked on the road of national liberation, national independence and increasing prosperity.
