Abstract: The "Three Representatives's" are the foundation underlying all our efforts to build the Party, the cornerstone for exercising political power and a source of strength of our Party. In order to remain a representative of the requirements of the development of China's advanced productive forces, it is necessary to push the socialist reform forward, develop science and technology, and raise the people's quality. To represent the orientation of the development of China's advanced culture is to persist in taking Marxism as the guide, strengthen socialist ideological and ethical building, and reflect the people's real life. To represent the fundamental interests of the overwhelming majority of the Chinese people, we must correctly handle the various interests among the overwhelming majority of the people and the relationships between the Party and the mass, the cadre and the mass, the early richness and the late.
