Our Party created and developed mass viewpoint of Marxism, put forward and persisted the mass line to do everything for the masses, believe in them, rely on them, from the masses to the masses and maintain close ties with them in the long-term struggle and practice. The Party's historical experience shows: the growth of the Party and the victory and development of the revolutionary are both closely related to the mass line. The mass line is the effective way for the Communist Party of China to have constructed our country, the "life line" of the Party and the country, and the Party's tradition and advantage. The theory and practice, history and reality, persistence and development of the mass line is a project we will study and explore forever. Learning the lessons and carrying out the experience of mass line need us to deal with some relationships properly.
