Learning the history of the Party means learning the history of the Party, carrying forward the fine traditions, inheriting the red genes, enhancing the Party's consciousness and party member consciousness, consciously practicing the socialist core values, vigorously carrying forward the national spirit with patriotism as the core and the spirit of the times with reform and innovation as the core, establishing political morality, being upright in conduct, abiding by public morality, being strict with private morality, always maintaining loyalty to the Party and childlike innocence to the people, and always maintaining the Party's advanced nature and purity.
