Marx's thought of people's press is not rigid but is always keeping pace with the time. From being impulsive to experienced, from the struggling war to the guidance of public opinions, from being radical to positive publicity, from being poetic to real discourse, Marx's thought of people's press has been emphasizing the organic properties of the press as well as the relationship of people's press and people's spirit. Having inherited and developed Marx's thought of people's press, Xi Jinping's thoughts on news publicity emphasize the principle of “running newspaper by politicians”, the unity of the Party spirit and people character, the unification of the positive publicity, and the supervision by public opinions, the people's interests as the highest value. The press must follow the inherent laws of itself.
