The publication of People's Daily was written by Sun Yat-sen, the leader of the League, who put forward the Three People's Principles for the first time: nationalism, civil rights and people's livelihood. This was the highest goal of the political revolution at that time-the three programs of the bourgeois national democratic revolution, and became the banner of the progressive political groups (including literary groups) at that time.

Although People's Daily is a political publication, it is also an indispensable guiding reading for progressive literary and art workers. Its editorial policy carries out Sun Yat-sen's three basic principles and advocates internally: subverting the current bad government, building a political system and state-owned land. The articles included in it are mainly political essays, with occasional comments and a few translated novels published. As an editor-in-chief and writer, Zhang often publishes his academic papers.

One of the important functions of People's Daily at that time was to have a sharp debate with Xinmin Cong Bao initiated by Liang Qichao and other reformers, refuting the reformers' ideas of constitutional monarchy, enlightened autocracy and opposition to public ownership of land, resisting the political influence of the reformers, promoting the development of the revolutionary movement and guiding the struggle direction of the broad masses of revolutionary people. For a time, it became the horn of the revolutionary struggle and played an important role in progress.
