One of the main contents of nationalism is "anti-Manchu". "Expulsion of Tatars and Restoration of China" has always been the battle slogan of bourgeois revolutionary democrats in the late Qing Dynasty. This is not only because the Qing Dynasty was a feudal autocratic regime dominated by Manchu nobles, but also because it has become a "foreigner's court". This is why the slogan of "anti-Manchu" has extensive mobilization significance. Avoiding the bad luck of China being divided and ruled by * * and striving for national independence and liberation is another main content of nationalism. In the People's Daily article, Sun Yat-sen listed "forced by foreign countries" and "forbidden by foreign countries" as the basic reasons of nationalism. "Non-revolution cannot save us from death", but the revolution must "overthrow the Manchu government first", and the significance of nationalism against imperialist oppression is contained here.

Civil rights are the core of the Three People's Principles. It reflects another major contradiction in modern China society, namely, the contradiction between feudalism and the masses of the people. The basic contents of democracy are: exposing and criticizing feudal absolutism, pointing out that the feudal social and political system deprived human rights, so it is by no means "unbearable for equal citizens"; It is necessary to overthrow the feudal monarchy by means of "national revolution" and replace it with "democratic constitutionalism" to end the serious state of "being confused by the poison of Millennium autocracy" In line with the "transformation" of this "state system", the division of political system also constitutes an important content of civil rights.

People's Livelihood is Sun Yat-sen's "social revolution" program, and the task it hopes to solve is the modernization of China, that is, to develop the capitalist economy and make China become rich from poverty; At the same time, it also contains the content of caring for the life and welfare of working people, as well as the criticism of capitalist social and economic ulcers and the resulting "sympathy for socialism." Sun Yat-sen summed up the main contents of people's livelihood as two major issues: land and capital. "Land equalization system"-"State-owned land" is Sun Yat-sen's land plan. The main content is "when improving the social and economic organization, the land price in the world is approved." Its existing land price still belongs to the original owner, and the price increase of social improvement and progress after the revolution belongs to the state and is enjoyed by the people. Sun Yat-sen believes that the implementation of this plan can prevent monopoly, make the public richer and promote "social development". On the issue of capital, Sun Yat-sen affirmed that "China needs industrialism". He believes that the modernization of China is an inevitable trend of history, and the book Industrial Plan is a grand blueprint for developing social economy. He summarized the way to develop social economy as "controlling capital" and developing "national socialism", that is, "exclusive large industries that cannot be entrusted to individuals" (such as railways, electricity and water conservancy) are all owned by the state, because this can not only "prevent the abuse of capitalist monopoly" but also "combine the resources of the whole country". People's livelihood is essentially a plan to maximize the development of capitalism, although it is painted with the color of subjective socialism.
