Experience: Adhere to safeguarding the vital interests of farmers, adhere to the indoctrination theory as the basis, adhere to the reality of rural areas and farmers, and the forms are flexible and diverse, which is conducive to farmers' understanding. Supplement: In the early days of the founding of the People's Republic of China, the state reformed capitalist industry and commerce. In the process of transformation, the capitalists as the parties show positive or negative thoughts and psychology, such as acceptance, resistance and worry. Studying the complex psychology of capitalists is helpful to understand the socialist transformation from another angle. With regard to the speed of the three great socialist changes in 1950s, most scholars think that the turning point is a critical movement to Deng Zihui's Walking with Little Feet. However, the author thinks that the deeper reason should be the domestic economic difficulties and the political and military pressure from the international side. It is precisely because of the grim situation of domestic troubles and foreign invasion that the decision-makers of the Communist Party of China have strengthened their strong control over the national economy in an all-round way and mobilized all forces to speed up economic construction in order to enhance the comprehensive strength of the country.
