(1) The widespread spread of Marxism in China provided an ideological basis for the establishment of the China * * * production party.

(2) The growth of the working class and the development of the workers' movement laid a class foundation for the establishment of the China * * * production party.

(3) After the May 4th Movement, a group of intellectuals with the initial thoughts of * * * productivism grew up, and they began to publicize Marxism among workers, and on this basis, they established a * * * productivism group, which further promoted the integration of the Marxist workers' movement in China.

(4) The external conditions were mainly the help of the * * * production international led by Lenin, which promoted the establishment of the * * * production party in China. Therefore, the establishment of the China * * * production party is the result of the economic and political development and ideological evolution of modern China, and the product of the combination of Marxism and the China workers' movement.

The combination of Marxism and the workers' movement is the general law of the emergence of working-class political parties and the basic principle of Lenin's theory of party building. ? Before the founding of the Party in China, China had developed the workers' movement and spread Marxism to a certain extent, and had the class and ideological conditions for the founding of the Party. Before the May 4th Movement, Marxism–Leninism spread in China, mainly among a few revolutionary intellectuals. The working class in China showed great strength in the May 4th Movement. Revolutionary intellectuals know the strength of workers through sports, which not only makes them pay attention to socialist theory and explore Marxist theory, but also urges them to take the road of combining with workers. Therefore, after the May 4th Movement, intellectuals with preliminary thoughts walked out of their study, spread Marxism-Leninism to the workers, and began the initial combination of Marxism-Leninism and the workers' movement in China. After the establishment of local * * production groups, it was made clear that engaging in the workers' movement was an important task, and Marxism-Leninism was spread to workers more consciously, organized and planned, so that Marxism-Leninism was further integrated with the workers' movement in China. First of all, we should publish popular publications to publicize Marxism among workers, publicize to workers that labor creates the world, expose the secret of capitalists exploiting workers' surplus value, and call on workers to organize. Secondly, establish workers' schools, labor cram schools, workers' night schools and workers' literacy classes to instill revolutionary ideas in workers, publicize why workers should organize trade unions and mobilize workers to fight for their own liberation. Third, organizing trade unions to lead workers against capitalists has effectively raised the consciousness of the working class. In addition, * * * capitalists also fought resolutely against various anti-Marxist ideological trends. Intellectuals with the initial thought of * * * productism, through combining with workers, further studied Marxism-Leninism, great changes have taken place in their political thoughts, and their world outlook has further changed, forming a group of early Marxists, which prepared the conditions for cadres for the establishment of the * * * Production Party in China. They put forward a series of party building ideas and prepared a theoretical program for party building. The party announced the official birth of China * * * Production Party, which marked the real combination of Marxism–Leninism and China workers' movement.
