In September 1920, Cai Hesen wrote to Mao Zedong to discuss issues related to the establishment of the CPC. The letter wrote, "The Party's discipline is iron discipline. Only in this way can we form a few extremely conscious and organized elements, adapt to the war era and shoulder the huge transformation cause.". Mao Zedong replied, "Your letter is insightful, and there is not a single word that I disagree with." "The Party's discipline is iron discipline," which has been a prominent symbol and political advantage of our Party since its founding. Strengthening discipline, revolution is invincible. From the First Program of the CPC adopted at the First National Congress of the Communist Party of China to the Constitution of the CPC adopted at the Second National Congress of the Communist Party of China, a chapter of "discipline" was set up; From the "Three Disciplines and Eight Points of Attention" during the Jinggangshan period, to the "Two Musts" and "Six Regulations" before the Party Central Committee's "Entering Beijing to Take the Exam"... One very important reason why our party has been able to continuously develop and grow from victory to victory is that we have always regarded strengthening discipline construction as an important guarantee for promoting the development of our cause. As American journalist Edgar Snow once lamented, "The methods and organization adopted by the Communist Party are strictly disciplined. Since the 18th National Congress of the Communist Party of China, the Party Central Committee with Comrade Xi Jinping as the core has always adhered to a strict tone, incorporated disciplinary construction into the overall layout of Party building, and revised the "Regulations on Disciplinary Actions of the Communist Party of China" three times, continuously sending a strong signal that the comprehensive strict governance of the Party is becoming increasingly strict and the enforcement of discipline is becoming stricter in the future, truly giving force to iron rules and prohibitions. On the new journey, we must place discipline construction in a more prominent position, using iron discipline to unite the will of iron, the style of hammering iron, and the team of forging iron, and unite the whole party into a "hard piece of steel". Strengthen discipline consciousness with 'iron discipline'. The discipline of the Party is mandatory, but at the same time, it must be based on the consciousness of Party members and cadres. For Party members and cadres, strict adherence to discipline relies not only on external discipline, but also on self-discipline; Not passively accepting, but actively practicing. Self awareness of discipline will not naturally form, it must be constantly learned, constantly practiced, constantly advanced, and constantly awakened. We must continue to strengthen the study of party discipline, clarify what the party's rules and regulations are, and understand what we can and cannot do. We must always hold a ruler and know what to do and what not to do, and effectively transform the external constraints of discipline into internal motivation and self-discipline for compliance and discipline. To strengthen the cultivation of party spirit, build a solid ideological defense line, understand the principle of "endless material desires, rules within the party, and bottom lines in interpersonal relationships", and continuously enhance political, disciplinary, moral, and anti-corruption determination. We should pay attention to being vigilant and taking action, take cases as a lesson, learn from them, and promote the transformation of lessons into teaching materials and actions through immersive experiences and immersive reflections, cultivating a high degree of consciousness of compliance and discipline. Standardize daily words and actions with 'iron discipline'. Discipline is a circle, freedom is within. Once a person lacks the constraints of discipline and rules, it is like a glass that has broken free from the box, and is not far from being shattered. In our daily work and life, we should be meticulous and take preventive measures, starting from small things and being strict with them. We should regulate our words and actions according to disciplinary requirements, correct any potential or tendency problems in a timely manner, and prevent small mistakes from turning into big ones. We must be consistent and cautious from the beginning, realizing that discipline can only be carried out when it is ongoing and not completed. We must always maintain a clear and firm sense of "rushing to the exam", tighten the string of discipline at all times, have a sense of awe and fear, and never do anything beyond the boundaries under any circumstances. Leaders and cadres are at the forefront of abiding by discipline, and they must lead by example, lead by example, and give full play to the "leading goose effect". They should measure themselves with stricter standards, demand higher standards of themselves, take the lead in strictly following the principles, discipline, and rules of the Party, consciously purify their social circle, life circle, and friends circle, cultivate the habit of working and living in a supervised and constrained environment, and use their own exemplary discipline to drive the "vast majority" to ensure the rigid implementation of Party discipline and reach the end. Promote responsibility with 'iron discipline'. President Xi Jinping emphasized that "by abiding by rules and regulations, one will have full freedom and broad space for work and entrepreneurship." The discipline of the Party and work and entrepreneurship are inherently unified, and Party members and cadres should not only strictly abide by the "iron discipline", but also have an iron like sense of responsibility. We need to have a correct understanding of the relationship between strict management and supervision, and encouraging responsible behavior. We should regard discipline as a "safety belt" for our career, rather than a "shield" for inaction. Under the premise of complying with rules and regulations, we should work hard, work freely, forge ahead, and actively take action. Party organizations at all levels should adhere to the combination of strict management and kindness, and give equal importance to incentives and constraints. They should take responsibility for those in charge, for those in charge, and for those in charge, and strive to create a good environment for entrepreneurship and activation of the "spring water" of responsibility. With the "iron discipline", they should provide strong guarantees for Party members and cadres to work and start businesses. (New Society)
