Correcting mistakes, being brave in cutting the blade inwards and scraping the bone to cure the poison ensure the Party's lasting prosperity and continuous development. "The whole world will be formed when the body is formed, and the whole world will be governed when the body is governed" is said in the article "Lu's Spring and Autumn Annals, Ji Chun Ji, Xianji". The original intention is to say that the ancient Ming Jun accomplished himself and thus the world; Correct yourself, and the world will be in order. It is emphasized that those who govern the world should first cultivate themselves, and self-cultivation is the rule of the family, the rule of the country, and the peace of the world. The chapter of "First Self" focuses on the core issue of how to govern the world. It advocates that "the foundation of everything is to govern the body first", "sages organize and cultivate their body, and write it down in the world", and believes that governing the world should seek all of themselves, and achieve the great cause of governing the country by setting an example of themselves. As a political organization that leads the people of all ethnic groups in the country to comprehensively build a socialist modern country and comprehensively promote the great rejuvenation of the Chinese nation, the success or failure of our Party's own construction is not only related to the life and death of the Party, but also to the national and people's well-being, and the survival of the socialist system. In a word, the party must be run before the country is run. How our Party "becomes its body" and how to "govern its body" need to be traced back in the century-old party history. After a hundred years of ups and downs, our party has developed from only over 50 party members and a few local organizations to the world's major party with more than 96 million party members and more than 4.9 million grass-roots party organizations. It can be said that it has achieved success, but it also faces unprecedented difficulties in party governance. It was pointed out that "how to always remember the original intention and mission, how to always unify the thought, the will and the action, how to always have a strong ruling ability and leadership level, how to always maintain the entrepreneurial spirit, how to always find and solve their own problems in a timely manner, and how to always maintain a clean and healthy political ecology are all the unique problems that our big party must solve." It is a hurdle that must be crossed to realize the Party's mission and task in the new era and new journey. It is a hard bone that must be chewed down to fully and strictly manage the Party and adapt to the new situation and new requirements. It requires Party members and cadres to improve the wisdom of judging the situation, actively responding to the situation, and the ability to see the smallest and prevent risks. It also requires them to strengthen their determination to distinguish right from wrong, reject corruption and respect integrity, and the endurance of combining hardness and softness and perseverance. After a hundred years of building the Party, we are determined to keep the original aspiration of the revolution. The development process of our party is one of perseverance
