In the party's mass line education practice, leading cadres are both organizers, participants and instructors. As the activities enter the stage of cross-checking and criticism, they will touch more on some deep-seated and substantive issues, which require the unremitting efforts of the whole party. In particular, it is necessary for leading cadres at all levels to implement the responsibility of "the first responsible person", strengthen their confidence, cheer up their spirits, truly put themselves in three aspects: correcting their thoughts and checking out problems, actively seize the "bull's nose" of educational practice activities, take the lead, and truly "put in" their correct thoughts. Thought is the forerunner of action. Only when thinking, understanding and attitude are in place can action be in place. Driven by the demonstration of the new central leading collective, the practice activities of mass line education in various localities and departments started well and progressed smoothly. There will be more difficulties and deeper problems in the "front" of continuing to promote practical education activities. Therefore, in the next stage of educational practice, leading cadres should first really "invest" in correct ideological understanding, correct wrong ideas, clarify vague understanding, strengthen their confidence, and promote educational practice with high standards and high quality with the belief of "sticking one pole in the end", strong sense of responsibility and serious work attitude. In particular, it is necessary to prevent negative thoughts and attitudes derived from "activities for the sake of activities", find out and effectively solve outstanding problems that affect and restrict the in-depth promotion of educational practice activities from ideological understanding and working ideas, so that educational practice activities can be carried out smoothly and orderly according to the established goals. Really "put it in" on the issue of investigation. The problem of checking and arranging is the core link of educational practice. Whether we can identify the problems, dig deep into the root causes and deeply analyze the reasons is directly related to the unclear thinking of the activities, the false rectification measures and the good results of the activities. Whether leading cadres, especially the "top leaders" really "invest" in the analysis and search is related to whether educational practice activities will become a mere formality and achieve due results. Therefore, leading cadres should "put" the problems strongly reflected by the masses in party member, and lead the team to go deep into the grassroots, the frontline and the masses, listen to the truth and touch the truth. Seriously organize special democratic life meetings, sort out and analyze the collected opinions, and fully and thoroughly talk about the heart-to-heart activities. We should seriously carry out criticism and self-criticism, dare to touch the truth, expose shortcomings, highlight ugliness, and truly touch the mind and soul. In particular, we should look for problems from "four winds", carefully analyze the root causes, find out the truth, dare to face problems directly, do not avoid contradictions, put an end to "good people's doctrine", and lay a foundation for party member cadres' self-purification, self-improvement, self-innovation and self-improvement. Really "put it in" in the implementation of rectification. Doing a good job in rectification and implementation is the key to ensuring the effectiveness of the party's mass line education practice and winning the satisfaction of the masses. The final result of educational practice activities is mainly reflected in the implementation of rectification, the effectiveness of activities and the satisfaction of the masses. Therefore, leading cadres should really "invest" in the rectification of the problem, take the lead in setting an example and take the lead in rectification. For the problems found out, dare to expose their own shortcomings, expose their own ugliness, and are not afraid of getting burned. They should first rectify themselves, ask others to do what they want to do, stand firm and take a firm attitude, start from themselves, start from now on, take the initiative to correct immediately, seek truth from facts, face it seriously and not perfunctory. In particular, it is necessary to intensify the special rectification of the "four winds" problem existing in the Party, seriously solve specific problems, strengthen discipline enforcement, severely punish those who disobey the wind and discipline, ensure that educational practice activities produce results and see actual results, and let the people truly feel the gratifying changes brought about by educational practice activities. It should be said that the orientation of leading cadres' words and deeds is clear, and the promotion of "number one" is a powerful guarantee for educational practice activities. Whether leading cadres can, are willing and dare to "put themselves in" reflects their attitude towards educational practice and their determination to change their style of work. Therefore, leading cadres should keep the educational practice firmly in mind, hang it in their hearts, grasp it in their hands, spend time and energy, ask questions and do it in person, implement the responsibility of "the first responsible person", further tighten the "screw buckle" and ensure good quality in future activities, ensure that the activities are not empty, empty, impartial and do not go through the motions, and win the trust of the people with tangible results.
