Abstract: Mutual conformity does not mean that the basic principles of Marxism and the excellent traditional Chinese culture have the same ideological concept, but refers to the unity of the two in the contradictory movement of commonness and individuality. In the “second combination”, commonness promotes thought empathy and mutual understanding, while individuality promotes theoretical complementation and mutual learning. The basic principles of Marxism and the excellent traditional Chinese culture can be combined because of their commonness,and just because it has individuality, it needs to be combined. Commonness and individuality are inseparable and dialectically unified in the “second combination”. In the contradictory movement of commonness and individuality, the basic principles of Marxism and the excellent traditional Chinese culture have internal commonness and complementary advantages, realizing discourse and theoretical innovation, and forming an organic and unified new cultural life entity.
