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. "" What I did is summed up these new things, be promoted. "This is a vivid manifestation of the Deng Xiaoping's mass. Deng also put people "support does not support", "agreed not to agree", "happy happy", "promise not to promise" as a starting point and 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 "created and 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", can always 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 cadres should develop a democratic style of work, come from the masses, to the masses, together, stick to the mass line.
