Party history:

China is an advanced political party under the guidance of Marxism. In the past 100 years of practice, we have constantly summed up the historical experience of self-construction, promoted the overall construction of the party's politics, ideology, organization, style, discipline and system, and grown into one of the few mature political parties with strong political leadership in the world.

China has also suffered historical setbacks, but he can face up to and solve practical problems, make himself more correct and powerful, and become the highest political leading force worthy of the great rejuvenation of the Chinese nation.

History of New China:

It is the history of China that promotes the construction of new China. Since its establishment, China has taken the pursuit of people's happiness and national rejuvenation as its own responsibility, and led the people to realize the great historical leap of the Chinese nation from standing up, becoming rich and becoming strong.

The history of reform and opening up:

After the Third Plenary Session of the Eleventh Central Committee of the Communist Party of China, the CPC Central Committee made a historic decision to implement reform and opening up based on a profound grasp of the future and destiny of the party and the country and a scientific insight into the historical development trend, which opened a new historical period of reform, opening up and socialist modernization. We will continue to promote the healthy development of various undertakings in China and make socialist China stand tall in the east of the world.

History of socialist development:

Carrying ideals and missions, socialism has experienced the development from fantasy to science, from theory to reality, from one country to many countries, and also experienced the dramatic changes from the Soviet Union and Eastern Europe to the vigorous rise of Socialism with Chinese characteristics. Along the way, there are both triumphs and twists and turns.

The history of world socialism development is the exploration history of mankind to get rid of the unequal, unfair and unreasonable exploitation system and realize a better social system. It is also the struggle history of the proletariat for its own liberation and the liberation of all mankind, which always represents the direction of mankind and always promotes the continuous development and reform of society.
