党性是共产党员的立身之本,没有党性的人不会是一个真正的共产党员,党性不强、不纯的人不可能成为一名合格的共产党员。党性修养就是共产党员按照党的性质、宗旨、纲领路线和指导思想等要求,通过学习、改造和锻炼,磨砺品格和意志,以保持政治上的坚定性和思想道德上的纯洁性,其 Party spirit is the foundation of the party members. People without the party spirit will not be a true communist party. It is not possible for an honest party character and an impure person to become a qualified party member. Party spirit cultivation means that party members, in accordance with the requirements of the Party’s nature, purpose, program line and guiding ideology, sharpen their character and their will by studying, reforming and exercising in order to maintain political firmness and ideological and moral purity.
