Nationalism: opposing national oppression and Manchu aristocratic rule; Democracy: overthrow the absolute monarchy and establish a national government; People's livelihood: equal land rights. Evaluation:

Progressiveness: The Three People's Principles is a relatively complete program of bourgeois democratic revolution, which comprehensively reflects the main contradictions in China's semi-colonial and semi-feudal society and tries to solve them by revolutionary means; It expresses the political and economic interests and demands of the bourgeoisie, reflects the common desire of the people of China for national independence and democratic rights, and promotes the development of the bourgeois revolution; Limitations: The Three People's Principles is an incomplete revolutionary program. It did not explicitly put forward the anti-imperialist requirements, nor did it have a thorough agrarian revolutionary program, which determined that the bourgeois revolutionaries could not completely complete the anti-imperialist and anti-feudal democratic revolutionary tasks.
