1954 September 15, the first session of the first national people's congress opened. The meeting adopted the first socialist constitution in the history of China, formulated the basic law of state institutions, and laid the basic framework of the people's congress system in China. The first National People's Congress can be said to be a milestone in the construction of democracy and legal system in China. The National People's Congress embodies the fundamental principle that all rights belong to the people and the people are masters of their own affairs. The National People's Congress (NPC) has become the highest authority in People's Republic of China (PRC). The people's congress system, as the most fundamental political system, has been systematically established from the central government to the local government in the land of new China, and a new era of people being masters of their own affairs has arrived. Eight contents: after the socialist transformation is basically completed, the main contradiction in China is no longer the contradiction between the working class and the bourgeoisie, but the contradiction between the people's demand for the establishment of an advanced industrial country and the reality of a backward agricultural country, and the contradiction between the people's need for rapid economic and cultural development and the current situation that the economy and culture cannot meet their needs. The solution to this contradiction is to develop social productive forces and implement large-scale economic construction. On the basis of summing up China's experience in implementing the First Five-Year Plan, the Congress continued to adhere to the policy of anti-conservative and anti-aggressive economic construction, that is, to make steady progress in a comprehensive balance. Significance: The Party's line formulated by the Eighth National Congress is correct, and many new principles and ideas put forward are full of creative spirit. Of course, due to the short practice time, it is impossible to be mature in theory and thought, and many new concepts and policies cannot be firmly established at the Eighth National Congress, thus realizing the profound exploration of China's own socialist road. After all, initial achievements have been made, and history has proved that these achievements have long-term significance for the development of the party's cause. 1At the end of 978, the Third Plenary Session of the Eleventh Central Committee of the Party was held in Beijing. The plenary session completely denied the "two whatevers" and re-established the ideological line of emancipating the mind and seeking truth from facts; Stop the slogan of "taking class struggle as the key link" and make up your mind to shift the focus of work to economic construction to implement reform and opening up; Form a collective leadership of the CPC Central Committee with Deng Xiaoping as the core; Review and solve a number of major problems left over from history and the merits and demerits of some important leaders.
