To ensure the overall leadership of the Party through comprehensively governing the Party with strict discipline embodies the law of the modern construction of Chinese socialism and reflects the internal logic of the "four greats". It would be impossible to strengthen the overall leadership of the Party in the new era without comprehensively governing the Party with strict discipline. High standards and drastic measures must be systematically and comprehensively applied in the entire process and all aspects of strictly managing and governing the Party. We must make strictly governing the Party entirely function to improve the Party's leadership. We must create upright and honest political ecology to provide a sound environment for comprehensively governing the Party with strict discipline. We must prevent the formation of interest groups to preserve the advanced nature of the Party. We must prevent and eliminate various dual-character phenomena to eliminate blind areas of comprehensively governing the Party with strict discipline.
