guarantee for the great struggle. This aspects XI General Secretary of speech main including exercise thrift, against extravagance mass line is party of lifeline and fundamental work route accurate grasp party of mass line education practice activities of guideline and target requirements set and develop "three strict three real" of style put power shut into system of cage in using history wisdom advance anti-corruption construction in-depth advance style clean government and anti-corruption struggle develop nail nail of spirit, a Zhang good of blueprint 9. other aspects. 18 big yilai, XI General Secretary also respectively on diplomatic, and military, and ecological construction, aspects published has important speech, covers has construction ecological civilization, and advance defense and army modern, and rich "one country, two systems" practice an
d advance country unified, and go peace development road, and promoted building new powers relationship, and go good around diplomatic work, and strengthening and developing countries solidarity cooperation, and active participation multilateral affairs, and science of thinking and work method, many aspects. XI Jinping, Secretary of a series of important speeches, and further enrich and develop the party's theory, line, principles and policies, the party puts forward new requirements for more contemporary features, the latest achievement of Marxism in China, is a guide to persisting and developing socialism with Chinese characteristics. Four methods. To address the relationship between comprehensive and focused on science. In the process of learning, we should follow as a good study and carry out the "wise men" to conduct a comprehensive collaborative learning; and with their own jobs, focus research and understanding spirit, grasp the potential requirements. For example, every party member should be according to the various branches of learning program, an article does not go into a link, no leakage of conducting a comprehensive study, and combined with their own duties and responsibilities, be focused and targeted Geoscience. Like, leaders to highlight learning XI on ruling acting political know of deep love of cut dry in practice go in forefront of river new language out poverty XI on coordination advance "four a full" strategy layout discusses excerpts XI on full deepening reform discusses excerpts XI on full law ruling discusses excerpts 18 big yilai XI on major economic problem discusses excerpts, discipline to highlight learning XI on strict party of di
scipline and rules discusses excerpts XI Jinping, on the construction of clean and honest Government and fight against corruption discussed excerpts, technology to highlight the learning of the XI Jinping on technological innovation and discusses excerpts, XI Jinping, education should highlight the important excerpts of work on education and so on. To address the relation between stage and often science. Phase has the advantage of time to focus on fast, to highlight the theme, focused, result; often learn the advantages of flexible fit, form, subtle, continues to
deepen. In General, periodic high priority on learning, easy to grasp and practice: recurrent learning factors, long time, prone to "sluggish". Learning programmes are explicitly required to learn education is not an event, but to highlight the normal education, differentiated levels, heart, catch a fine practice, the real party's ideological and political construction in the everyday, often. This requires that we do a good job phase focused learning based on knowledge contests, comments on rewards in the form, pay special attention to recurring studies. To handle the relationship between solid strong to learn and a lot to learn. For any unit or individual, objectively speaking, in the process of carrying out the party Constitution Party rules and spirit, there is a problem with strong and weak, which we need to pay attention to the actual learning content, and handle the relationship between solid strong to learn and a lot to learn. On one hand, we must always keep a humble attitude, good d
eal, Continue the hardening. The other hand, always keep the spirit of energetic, pegged to the weak link to find gaps, fill the short Board. Short Board issues should not be underestimated, the saying goes, have short Board, add a short. This tells us, there are weaknesses shortcomings and do not be afraid, fear is a blind eye and not to repair, the result is poor is worse and the weak weaker. United States politics home zhamusi, and Wilson and prevention crime learn experts qiaozhikailin proposed has a famous of broken window theory, that, if a building House has a fan window of glass broken has, and this fan Windows no get timely repair, others on May to broke more of window glass, time a long, these damaged of window on to people caused a disorder, and matter of feel, results in this mass errors think no attention, and no management of atmosphere Xia, some bad culture, and violations behavior on will breeding and spread. Reality life in the is such, clean of wall Shang, suddenly was posted has a Zhang ad, if didn't people management, not out days this wall Shang on will appeared greatly small many of advertising; private take mess built phenomenon is so, began circle a small block to built a small shed put things, if didn't people timely stop, he on dare built a hut live people, time long has didn't people tube, wants to tube Shi on difficult has. Therefore, the solid strong is important, a lot to learn is also important. Third, key, grasp the learning objective of education is to train a qualified party member "two" study and education to its core essence is learning and doing. Learning and doing are mutually reinforcing, if optical can't do, study leave, real l
化工复合软管earning deficiency, while sweating, wind and water, "one fishing white" became "fake words and not the mules". Learning party rules did not comply with the party Constitution, address the learning series is not used, instead, learn and do, imagine this "learning", how do you meet the eligibility requirements of party members. Therefore, the "two" basic learning, the key is in use, do, line. In particular, is a qualified party members to grasp the following three points. To strengthen "four ------------------------------------------------- 3
