problems that cannot be ignored. Some leaders unwilling to do masses work, masses concept weak, on masses feelings not deep, pendulum not are with masses of relationship, think masses work is revolutionary war era of things, now obsolete has, buried business work, ignored masses work of situation compared General; some leaders not do masses work, old method regardless of with, new not with, not understand masses psychological, not understand masses wishes, not said masses language, work method simple stiff, caused masses of conflict and antipathy; some leaders can't do masses work, Faced with a lot of contradictions among the people worry about fear, panic set in encounter group events, and some are even mismanaged, inflame, so work has suffered heavy losses, and so on. These problems we are soberly aware, enhancing the party's ruling capability, the maintenance and development of the party's advanced nature and purity, and to enhance the ability of party committees and leading cadres are good people. Attach great importance to and is good at doing mass work, has become the new urgent situation strengthening the party's governing capacity-building tasks. Combined practice of maintaining flesh-and-blood ties with the masses, urged the broad masses of party members and cadres, especially all levels ... Processing to improve as a guide to the country. \se new things, be promoted. \d manifestation of the Deng Xiaoping's mass. Deng also put people \s not support\not to agree\happy\omise\nd destination of developing guidelines, policies, and as the only standard for measuring compliance with the wishes of the masses of the people. Under the guidance of Deng Xiaoping theory, Central Government adopted a series of important measures to strengthen links with the masses. In December 1989, the CPC Central Committee made on adhering to and perfecting the system of multi-party cooperation and political consultation under the leadership of the Chinese Communist Party, closely for CPC and the democratic parties and the relationship between the part of the masses that they contact, effectively carrying out the mass line, played a positive role. In March 1990, the 13 plenary session adopted the decision on strengthening contacts with the masses of the Party noted that \nd developed in the long struggle of the party's mass line, is to realize the party's ideological line, the fundamental political and organizational work route\s maintain flesh-and-blood ties and development of the masses, is directly related to the rise and fall of the rise and fall of the party and State. In September 1994, 14 adopted by the plenary session of the Party on strengthening decision on several major issues of party building. The requirements of the decision of the party's leading bodies and leading cadreshould develop a democratic style of work, come from the masses, to the masses, together, stick to the mass line. Party of 13 session four in the plenary yihou, to Jiang comrade for core of party常用玻璃量器检定操作规程（衡量法）

f third generation Central led collective, banner Deng Xiao-ping's theory great flag, insisted liberation thought, and facts, and times, in both at home and abroad political storm, and economic risk, severe test before, relies on party and people, defended China features Socialist, created socialist market new system, created full open new situation, advance party of construction new of great engineering, founded \sentative\nt thought, Continue to steer the ship of reform and opening up forward on the right. Comrade Jiang Zemin said: \ngthening and improving the party's mass work in the new situation, it is of decisive significance to consolidating the ruling Foundation of the party. \hrough our party and some of the world's major lessons learned from the success of the old party of the party, Comrade Jiang Zemin pointed out:\political advantage of our party is in close contact with the masses, the most dangerous after the ruling party was divorced from the masses. %uction, only the understanding, support and participation of the people, people's enthusiasm and creativity into full play in order to advance; the leadership of the party, only the tie and win the masses embraced, can be consolidated and strengthened. \d out that strengthening and improving the party's work style construction, maintaining the party's flesh-and-blood ties with the masses is the core problem, the key is to do solid work, implement, resolutely oppose and overcome formalism. Comrade Jiang Zemin stressed that all the work and policies of the party, are in compliance with the fundamental interests of the overwhelming majority of the people to the highest degree, to the majority of people are not satisfied with the fundamental guidelines, strive to make our workers, farmers, intellectuals and other people enjoy ... Single, everyone seemed to know. But well known does not mean perfect. Some party members and leading cadres, consider contacting their small departments, within a small circle of people, or contact individual owners, the entrepreneur, is the masses, this idea is obviously not correct. The Communist Party of China, people should have three characteristics. First, the people should be the most social, is a Department within the scope of the majority. Specific to the party and Government departments, especially the cadres working in the Central and State organs, mass is the 1.3 billion Chinese people, work for the party members and cadres, masses are the land within the jurisdiction of the common people. The second characteristic of the masses, is that we have common interests. Masses are manifestations of each specific people, but the crowd is a comprehensive political concept, refers to people with common political and economic interests in the period of social transformation, social differentiation between the interests of the masses is large, if you do not find the interest in doing mass work, the party members and cadres, will be in a passive position. The third characteristic of the masses
