The two regulations supporting each other, the code adhere to a positive advocate, focusing on morality is of Party members and Party leading cadres can see, enough to get a high standard。 the second part is the interpretation of the two fundamental principles of the revision of laws and regulations in the party。 the fourth part on how to grasp the implementation of the two regulations of the party. code and Regulations revised the necessity and revised 17 history of the CPC Central Committee the amendment to the Chinese Communist Party members and leading cadres honest politics several guidelines and Chinese Communist Party discipline and Punishment Regulations column 1 by 2020 to strengthen party laws and regulations focus. Two party regulations revision work lasted a Years, pooling the wisdom of the whole party, ideological consensus, draw historical experience, respect for the wisdom of our predecessors, which reflects the unity of inheritance and innovation。s leadership, to solve the masses of the people reflect a focus on the problem. The new revision of the code and rule , reflects the party39。s eighteen years prehensive strictly practice. (a) revised two regulations of the party need of the ICAC guidelines in in 1997 Leaders as members of the Communist Party of China clean politics certain criteria (Trial) based on revised, the promulgation and implementation of January 2020, to strengthen the construction of the contingent of leading cadres play an 18 important role. But with the party to manage the party strictly administering the deepening, has not been able to fully meet the actual needs. Content is too plicated, eight prohibition, 52 are not allowed to hard to remember, and also difficult to put into practice。 the third is banned terms and discipline law, both with the party discipline, disciplinary regulations repeat and Criminal law and other laws and regulations repeat。 two is the political discipline regulations is not prominent, not specific, for violation of the party constitution, damage the 19 authority of Party Constitution of misconduct lack necessary and serious responsibility to pursue。s eighteen, ten eight plenary, the spirit of the Fourth Plenary Session of the Eleventh Central Committee and General Secretary Xi Jinping important instructions on the revised low political criterion and Regulations , highlighting the ruling party characteristics, serious discipline, the discipline quite in front of the law, based on the current, a longterm, advance as a whole, with Bu Xiuding independent rule and rule . Main principle is: first, adhere to the party constitution to follow. The constitution about discipline and selfdiscipline required specific, awaken the party constitution of party passes party consciousness, maintaining the authority of the constitution. General Secretary Xi Jinping pointed out that no rules, no side round. Party constitution is the fundamental law, the party must follow the general rules. In early 2020 held the eighth session of the Central Commission for Discipline Inspection Fifth Plenary Session of the 16th Central Committee, Xi Jinping again pointed out that constitution is the party must follow the general rules, but also the general rules. the revision of the 22 code and rule is Method in adhere to the regulations established for the purpose of bining rule of virtue is to adhere to the party constitution as a fundamental to follow, the constitution authority set up, wake up the party constitution and party rules the sense of discipline, the party constitution about discipline and selfdiscipline specific requirements. 4 second is to adhere to in accordance with the regulations governing the party and the party. The Party of rule of virtue de, mainly refers to the party39。s eighteen years strict political discipline and political rules, anization and discipl
