As the core of the first generation of our party's collective leadership, Comrade Mao Zedong led the China Productivity Party and the people of all ethnic groups in China under the historical conditions, and combined the universal truth of Marxism with the concrete reality of China's revolution and construction, and made arduous explorations for realizing, consolidating, perfecting and developing China's socialism. I. Mao Zedong's Specific Proposition on the Socialist Construction Road in China In order to explore the socialist construction road suitable for China's characteristics, Mao Zedong has made unremitting efforts to combine the basic principles of Marxism with the concrete reality of China; Based on the reality of China, theoretical analysis and practical experiments are carried out. He left politics; Economic, cultural and other aspects, explored the socialist construction in China; It laid the foundation for Socialism with Chinese characteristics's theory and practice. Politically, Mao Zedong believes that the core of China's socialist politics is the implementation of the people's democratic dictatorship, and the organizational form of state power adopted by the people's democratic dictatorship is the people's congress system organized according to the principle of democratic centralism. At the same time, the system of multi-party cooperation and political consultation under the leadership of China Producers' Party will be implemented. Mao Zedong creatively put forward the class dictatorship with China characteristics-the people's democratic dictatorship by applying the Marxist theory of state and combining with the reality of China. This is Mao Zedong's enrichment and development of Marxist theory of state, and it is a socialist politics with China characteristics. From the economic point of view, it is reflected in his exploration of how to build socialism in China. He stressed that we should not mechanically copy foreign experience, but proceed from the situation that China is a big agricultural country, correctly handle the relationship between heavy industry, agriculture and light industry on the basis of agriculture, and take the road of industrialization suitable for China's national conditions. He creatively put forward the order of "agriculture, light and heavy", which proved its correctness for practice. Mao Zedong put forward the principle of independence and self-reliance in socialist construction, and put the foothold on the basis of self-reliance. This is by no means not wanting foreign aid, but focusing on relying on our own strength. Under the guidance of this policy, China has successfully overcome many difficulties, including those caused by the imperialist blockade. Culturally, Mao Zedong advocated adhering to the policy of "letting a hundred flowers blossom and a hundred schools of thought contend" guided by Marxism, extensively absorbing and critically inheriting all outstanding cultural achievements at all times and in all countries, and establishing his own national, scientific and popular culture. The policy of "letting a hundred flowers blossom" put forward by him has been written into the eight documents of joining the Party, and it has officially become the policy of developing scientific socialist cultural undertakings in China. He pointed out that letting a hundred flowers blossom and a hundred schools of thought contend means that different forms and styles in art can be freely debated. It is harmful to the development of art and science to use administrative power to force one style and genre and prohibit another. But this does not mean that there is an objective standard. Second, Mao Zedong's main viewpoint of consolidating socialism. He first put forward the viewpoint that there are contradictions in socialist society, and divided the contradictions in socialist society into two categories: contradictions among the people and contradictions between ourselves and the enemy. He believes that on the one hand, the contradictions in socialist society are generally non-confrontational, but on the other hand, the contradictions between the enemy and ourselves still exist and may even intensify. Therefore, he proposed not to confuse two different contradictions, but to pay special attention to correctly handling contradictions among the people; But if you can't relax your vigilance and think that you have no contradiction with the enemy, you can rest assured. This is Mao Zedong's great development of Marxism. Mao Zedong put forward the viewpoint that we should be alert to the conspiracy of imperialism to "peacefully evolve" socialist countries, and put forward that the most important thing to prevent "peaceful evolution" is the leaders and leading bodies within the party, especially within the party. Related to this, he has always attached great importance to the emergence of corruption in the opposition party and made unremitting efforts to this end. He has always been vigilant in maintaining China's security and resisted military provocations and various pressures from abroad. Thirdly, it is of practical significance to study the construction theory and practice of Mao Zedong and Socialism with Chinese characteristics. Although Mao Zedong's exploration has both the right side and the wrong side, his rich experience, lessons and ideological wealth provide valuable nutrition and reference for today's socialist modernization. It can be said that Mao Zedong's exploration played a founder role in the formation of Socialism with Chinese characteristics's theory. Under the leadership of Mao Zedong, China has opened up a unique road of socialist construction and made brilliant achievements. The victory and development of China's socialist cause are inseparable from Mao Zedong's leadership. Mao Zedong's contribution is enormous. His theory and practice left an indelible mark on the history of China, especially the history of New China, and played a decisive role in the later historical development of New China. His name is closely related to China's socialist cause. Studying Mao Zedong's theory of socialist construction can affirm its valuable aspects, not only affirming Mao Zedong's historical achievements realistically, but also relating to the future and destiny of socialist China.
