The history of the Red Army’ s Long March with hardship and suffering is a history of self-revolution of the Communist Party of China. Duning the long March, the Chinese Communists dared to turn blades inward. In terms of the direction of advance, we resolutely abandoned the original marching line and chose the direction in which the enemy’ s strength was relatively weak; in terms of central leadership, we promptly replaced the “left” adventurist leaders and established the central leading collective represented by Comrade Mao Zedong; in terms of operational policy, we decisively abandoned the dogmatic and rigid tactics and implemented flexible and flexible tactics; in terms of strategic choices, we resolutely opposed Zhang Guotao’ s erroneous proposition of going south 34 and carried the banner of going north to resist Japan; in terms of political life, we resolutely opposed separatist activities, and applied the principle of unity to solve the present urgent problems; in terms of the mental state, we resolutely overcomed pessimism and disappointment and built up revolutionary optimism. It can be said that self- revolution is an important factor of the victory of the Red Army’s Long March.
