party. No party Comrade. XII of the rules and regulations, the law is difficult to guarantee. "Bring order out of chaos at the beginning, our party began to amend the constitution, to the party promulgated the current constitution, it is our party is in office the best since the party constitutions. Comrade Jiang Zemin pointed out:" we discuss the strengthening of political discipline, the most basic is to abide by the constitution, according to the constitution of the provisions to do. The constitution of the provisions, all Party members must abide by, senior cadres should take the lead in compliance. Comrade Hu Jintao pointed out: "the state laws, the party constitution of the party constitution is to regulate and control the party constitution. For me this has nearly 70 million Party members of the party, the party's thought Unified constitution, selfAnd sleep in accordance with the constitution, has the extremely significant significance. Our party has always been high degree of attention to the party constitution, has always been to develop and perfect party constitution, study and implement the party constitution as the party's construction of a basic work and unremitting efforts to push forward. Our party has always attached great importance to the Party Chapter, is because they can not effectively learning the party constitution, abide by the Constitution and implementation of the party constitution, safeguard Party Constitution, to enhance the party's creativity, cohesion and combat effectiveness, to consolidate the party's ruling status and keep the party's advanced nature, related to the Party's cause success or failure of the party's life and death survival. We must from such a strategic height to recognize the problem. "The Party of ten Invariant are from a total of eight years, Xi Jinping, general secretary of the high degree of attention to play the Constitution's basic guiding role. Became general secretary, he published the first article in a signed article is < conscientiously study the party constitution strictly abide by Party Constitution. In the eighteenth session of the Central Commission for discipline inspection of the second plenary session of the 16th Central Committee, he again pointed out: "the constitution is the party's constitution, general rules for the strict political discipline to observe and safeguard the constitution of." "every Communist Party member especially cadre of leaders to firmly establish the constitution of awareness, and consciously with the constitution to regulate their own words and deeds, in any case have to do political belief, political stand, political direction without bias." in the eighteenth session of the Central Commission for Discipline Inspection Put, everything are extremely important in the construction of the party in the Fifth Plenary Session of the important speech, he and a stressed: "the constitution is the party must follow the general rules and general rules. Xi Jinping, general secretary of the exposition, profoundly expounded the partyyuan, an increase of 17.5%; local government general budget revenue of 500 million Yuan, .

The Party Constitution of the party and the party construction of the basic norms of behavior, which is the whole Party must follow the general rules and general rules. How seriously study the party constitution strictly abide by Party Constitution seriously study the party constitution, strictly abide by the constitution, is Xi Jinping, general secretary of the Party issued a call to arms. He pointed out:" to seriously study the party constitution, strictly abide by the constitution, is to strengthen the Frequently in the party's construction of a basic work, but also all comrades in the party should do our duty and solemn responsibility to strengthen the party constitution consciousness, enhance the party's creativity, cohesion and combat effectiveness has a very important role to the Party of 18 big party constitution amendment promulgated as an opportunity, in the party rise study party constitution, abide by Party Constitution of the boom. "The constitution as the foundation for building the party being in charge of the party constitution, general rules, the condensation of the party for a long time the formation of valuable experience and wisdom, on behalf of the party's fundamental volition is standard within the party political life, the adjustment of inner party relations, norms and constraints of the whole party behavior of the fundamental law of the party construction of fundamental Tube through the guiding role, which is to strengthen the party's construction of the "Outline". To strengthen the party's construction, the most fundamental task is to study and implement the party constitution, the basic way is to study and implement the party constitution. Therefore, it is necessary to put serious study party constitution, strictly abide by the constitution to the party's ideological construction, organizational construction, style construction, corruption and advocating honesty construction and system construction of the whole process and all aspects. Comprehensive strictly, from where the "strict", how to "strict"? The most important is to seriously study the party constitution, strictly abide by the constitution. The constitution is the party constitution, general rules that now exist within the party all sorts of problems, in the final analysis is a violation of the provisions of the constitution. The education of learning party constitution learning "is not the implementation of the provisions of the Constitution and carrying out the ineffective implementation caused. If the constitution the provisions of specific, practical and effective implementation of all comrades in the party and the party organizations at all levels, a comprehensive strictly and to basically achieve the central decision, 2016 in all Party members to carry out learning the party constitution, party rules, a series of speech, do a qualified party member education, and to study the Constitution in the first place, the truth in here. To do a good job ofnew measures to promote work, the courage to take responsibility, dare to break hard to ensure district, Government decisions and arrangements to implement. (B) strengthening supervision, severely punish acts of violation. One is to open the channels of supervision. Vigorously promote the party affairs public, open, widely accepted supervision by the masses, pay attention to social groups and public opinion supervision, the powerful force formed to urge party members and leading cadres properly exercise their powers. Second, strong supervision and inspection. Democratic life into full play, important briefings, reports related to personal matters and evaluation of cadres ' study of inner-party supervisory system, a comprehensive grasp of guidelines for the implementation of the independent Commission against corruption-related cases of leading cadres of party members, focus on strengthening key areas of project selection, funding, officials monitor, detect and rectify the problem, promote honesty in poli
