Implementing the three major democracies of politics, economy, and military within the military is a unique political advantage that sets our military region apart from other armies, and it is also an important weapon for the people's army to overcome the enemy and win. In the era of revolutionary war, one of the very important reasons why our army was able to win more with less, stronger with weakness, and better with inferiority was to achieve the three major goals of "high political unity, improvement in life, and military advancement in technology and tactics" by extensively and deeply carrying out the "Three Great Democracy" movements. In the new era and new journey, to achieve the centenary goal of building the military as scheduled and accelerate the construction of the People's Army into a world-class military, it is necessary to inherit and promote this fine tradition, and let the "three major democracies" accelerate the development of a strong military, injecting new momentum into winning battles. The implementation of the "three major democracies" is the unique political advantage of the people's army. The implementation of the "three major democracies" within the people's army is a great initiative of the CPC. It fundamentally changed the management system and leadership methods of officers oppressing soldiers in the old army, established a new relationship between officers and soldiers, maximized the enthusiasm and creativity of all officers and soldiers, and ensured the CPC's absolute leadership over the army and the unity of the army. At the beginning of the establishment of our army, the personnel were composed of various complex identities. Influenced by feudal traditional concepts and the style of old military warlords, the phenomenon of indiscriminate beating, scolding, and corporal punishment of soldiers was severe, greatly affecting the unity and combat effectiveness of the army. At the same time, the military cannot compare with the Kuomintang army in terms of manpower, material resources, financial resources, and weapons and equipment. In the face of a powerful enemy, in order for the People's Army to win the struggle, it not only needs strong leadership from the Party, but also needs to fully mobilize the fighting enthusiasm of the vast number of officers and soldiers, stimulate their fighting will, and form a winning advantage of "those who share the same desire from top to bottom win". The implementation of democratic system within the army is an important principle of building and running the army gradually formed in the struggle practice under the leadership of the CPC. Comrade Mao Zedong once proposed, "Not only do the people in China need democracy, but the military also needs democracy." In 1927, Comrade Mao Zedong led the Autumn Harvest Uprising on the Hunan Jiangxi border to reorganize the Three Bays and announced the implementation of a democratic system within the military, stipulating equal treatment for officers and soldiers, open economy, and the freedom of soldiers to speak at meetings; Soldier committees shall be established at all levels below the regiment level, representing the interests of soldiers and participating in military management. In 1929, the Resolution of the Gutian Conference stipulated that there was only a distinction between officers and soldiers based on their positions, and no distinction based on class; Implement a democratic life under centralized guidance, resolutely abolish corporal punishment, prohibit verbal abuse, give soldiers the right to speak, and oppose retaliation; Overcoming extreme democratization and ensuring the normal development of democratic life. During the War of Resistance Against Japan, various units used the method of rectification, held democratic meetings to check the relationship between officers and soldiers, corrected warlordism tendencies, carried out the movement of respecting cadres and loving soldiers, enhanced close friendship, strengthened internal unity, and further developed the democratic life of the troops. During the War of Liberation, the entire army launched a new type of military integration movement, which generally adopted democratic methods, implemented class education, reorganized organizations, inspected work, and evaluated party members and cadres; During combat, mobilizing the masses to discuss how to complete combat tasks further strengthens the democratic atmosphere of the military. 1948
