of 16 session brought to adhere to people-oriented, all-round, coordinated and sustainable scientific development view, promoting economic and social and human development. The core of the scientific Outlook on development is people-oriented. Implement the scientific concept of development and first implementation of people-oriented requirements. Office of the Party Committee of this year's work, we have to firmly establish the idea of people-oriented philosophy, richness of understanding the people-oriented, seriously implement people-oriented requirements correctly grasping the practice of people-oriented, through people-oriented "three services" working process, pushing the city Party Committee Office work to a new level. Investee (b) investee by people-oriented, in the final analysis is centred, human premise, a human-powered, human purpose. People-oriented thinking long. As early as the spring and Autumn period of more than 2000 years ago, Qi Guan Zhong: "overlord of the beginning, and people-oriented. Principle of the solid. "For thousands of years, traditional Chinese political culture there is a wide variety of people-oriented thought. Pan Geng's "people" to the Duke of Zhou's "protect" and then to Confucius ' "man", from his "your KingLight "to the idea of" Grand boat water "and then to advocate since the Han and Tang dynasties" nation ", these useful idea is, is the country of the people, political sources. The rulers of "people", the "San Zhi bei yan" the rulers of "thin people", then "died suddenly". The West ever since the Renaissance, it is because of the rise of humanism, really started to self awareness, self discovery and self-reflection. Predecessors in criticism of Marx and Engels thought on the basis of the outcome of, according to the great discovery of historical materialism, reveals the true nature of human existence, the ideology was essential and strongly suggests, as provided. In 1894, the Engels from Marx's writings, singled out his favorite passage for the new century weekly solemn inscriptions: "there, the free development of each is the free development of all people". In modern society, people-oriented thinking more and more attention. People generally regard it as a kind of economic and social development, a principle, a requirement, as a need to maintain the interest of the people of, a pursuit, a purpose. This idea was praised, with the profound connotation and practical significance. Investee 1. people answering epistemological questions and answered the questions of methodology. People contains a profound philosophical, epistemological and methodological significance of science. Known as epistemology, refers to the theories on the relationship between knowledge and practice. In the view of Marx and Engels, "man is man's world, is the State, society, and history writers and characters. "In other words, the world is one world, society is human society. We know the society, starting from the people to observe; we know the practice, from the people to study; we knew Office work, from the people who set out to explore.

Methodology refers to methods of knowing the world, transforming the world's theory. Historical materialism tells us that social development, leave is impossible; all social progress, leaving people unable to achieve. We do anything, must first of all take into account the human factor, to find ways to give full play to the initiative and human creativity, mobilizing people's enthusiasm. This is the result of numerous historical practice of most of the scientific method. Emperor Taizong"The world of excellence into my opponent" and "Zhenguan rule", Qing Zeng Guofan to "more aides for the first prerequisite" Zhong XING Ming Chen, are insisting on methodology of successful models. Promoting the reform and development, construction of well-off, more demands that we as a people-oriented scientific method. We do work in the countryside, it is necessary to put farmers first we engage in State-owned enterprise reform, we must regard expanding employment as an important goal we created urban, optimization-Habitat environment must be pursued. Promotion Office, too, only man's subject status, to achieve rapid development. Investee 2. people who responded to the question, and replied to questions depending on who. Who issues, is concerned with the problem of the ruling party; depending on who issues are questions relating to the source of power of the ruling party. Look at the trend of the world, throughout the ages, no party's fate was not to be dominated by people, no Albert is not driven by the people of a nation. Our party has always attached importance to people, caring for people, his people as the coldest winter, parents of people as their own, but there were also some in adhere to people-oriented bias, war "sufan expansion" peacetime "cultural revolution", has caused a great loss to the revolution and construction. Through history, our party proved that when people, caring for people, and along the way there is a powerful force; when to ignore people's thinking, to ignore the interests and needs of the people, the party's cause will suffer setbacks. People-oriented, power for the people, this is the most fundamental rules governing laws, large and small, every aspect is also ruling is the most essential requirements. Set up the people-oriented concept of governance, requires us to establish the main position, everything for the masses, rely on the masses, and consciously do right for the people, show concern for the benefit of people and bring benefit to the people, real people as masters of the country, construction of the main body and the cause of main. From this perspective, adhere to the people-oriented and that is power for the people is to uphold the mass viewpoint and the mass line of the party. Office work is serving the overall work of the party. Only around the service objects, service, relying on the service principal to the service in order to Shun Water push the boat, a long-term perspective, creating impressive performance.
