Theoretical maturity is the foundation of political maturity, and political firmness stems from theoretical sobriety. Persisting in arming the entire Party with the latest achievements in the sinicization and modernization of Marxism, guiding practice, and promoting work is an important experience for our Party to create history and achieve brilliant achievements. Every time the Party advances in theoretical innovation, its theoretical arm must follow suit. Consciously arming the mind with the latest achievements in the sinicization and modernization of Marxism, and guiding new practice with the developing Marxism, are valuable experiences for our party and country to continuously move from victory to victory.

After the Third Plenary Session of the 11th Central Committee of the Communist Party of China, our party adhered to the combination of the basic principles of Marxism with China's specific realities, established Deng Xiaoping Theory, formed the important thought of "Three Represents", and the scientific development concept, constantly promoting the modernization of Marxism in China, maintaining the guiding ideology of the party to keep pace with the times, and constantly promoting the great cause of socialism with Chinese characteristics.
