What exactly does the Three People's Principles refer to? and explain.

(1) Nationalism opposes national oppression and the rule of the Manchu aristocracy. The Chinese nation seeks its own liberation and opposes imperialist aggression. All ethnic groups in China are equal

(2) Civil rights Doctrine overthrows the autocratic monarchy and establishes a national government. All citizens are equal and civil rights are enjoyed by ordinary people. Individuals and groups that truly oppose imperialism are entitled to all freedoms and rights

(3 ) People's Livelihood Principles Equalize Land Rights and Control Capital

One of the main contents of nationalism is "anti-Manchu". "Drive out the Tartars and restore China" has always been the battle cry of the bourgeois revolutionary democrats in the late Qing Dynasty. This was not only because the Qing Dynasty was a feudal autocratic regime "dominated" by Manchu nobles, but also because it had become a "foreign court." This is why the "anti-Manchu" slogan has broad mobilizing significance. Avoiding the fate of China being partitioned and communist and striving for national independence and liberation is another main content of nationalism. In an article published in Minbao, Sun Yat-sen listed "forced by foreign countries" and "remnated by alien species" as the basic reasons why nationalism "cannot be delayed even for a moment." "There is no way to save the dying without revolution," and revolution must "first overthrow the Manchu government." This is where the significance of nationalism's opposition to imperialist oppression lies.

Democracy is the core of the Three People's Principles. It reflects another major contradiction in modern Chinese society, that is, the contradiction between feudalism and the masses of the people. The basic content of civil rights is: to expose and criticize feudal despotism, pointing out that the feudal social and political system deprives human rights and is therefore by no means "bearable by equal citizens"; it is necessary to overthrow the feudal monarchy through the "national revolution" and replace it. With the "democratic and constitutional" democracy and system, we will put an end to the serious state of "the poison of a thousand years of autocracy that has not been cured". In line with this "reform" of the "state system", the planning of the political system also constitutes an important part of civil rights.

People's Livelihood Principle is Sun Yat-sen's "social revolution" program. The issue it hopes to solve is China's modernization, that is, developing a capitalist economy and making China rich and powerful from poverty and weakness; it also includes caring for the lives of working people. the content of welfare, as well as a critique of the socioeconomic ulcers of capitalism and the resulting “sympathy for socialism.” Sun Yat-sen attributed the main content of people's livelihood doctrine to the two major issues of land and capital. "Equal land rights" - "state-owned land" is Sun Yat-sen's land plan. The main content is "We should improve the social and economic organization and determine the price of land in the world. The existing land value will still belong to the original owner, and the increased value of social improvements and progress after the revolution will belong to the country and be enjoyed by the people." Sun Yat-sen believed that the implementation of this plan could prevent monopoly and make "the public wealthier", thus promoting "social development". On the issue of capital, Sun Yat-sen confirmed that "industrialism is necessary for China." He believes that China's modernization is an inevitable trend in history, and the book "Industrial Plan" is the grand blueprint for social and economic development. He attributed the way to develop the social economy to "controlling capital" and developing "state socialism", that is, "big industries" (such as railways, electricity, water conservancy, etc.) that "cannot be left to individuals and have an exclusive nature" "are all state-owned ", because this can not only "prevent the abuses of capitalist monopoly", but also "combine the resources of the whole country." People's Livelihood is essentially a plan to develop capitalism to the maximum extent, although it is colored by subjective socialism.
