Resolutely safeguarding the authority and centralized and unified leadership of the Party Central Committee is a major party building principle of a Marxist party. Only by resolutely upholding the authority and centralized and unified leadership of the Party Central Committee can we firmly unite the 96 million plus party members and 4.9 million plus grass-roots party organizations of the whole party, and then closely unite the people of all ethnic groups across the country to form an invincible and powerful force with one heart and one mind, so as to win the victory of the great struggle with many new historical characteristics. Today, the decisive significance of the "two determinations" is deeply rooted in the hearts of the people. The whole Party has further enhanced its political, ideological, and action consciousness in "Four Consciousness", strengthened its "four self-confidence", and achieved "two safeguards". Its resolute maintenance of the authority of the party Central Committee and its centralized and unified leadership have been comprehensively strengthened. The development of the party's cause has a stronger political guarantee. Resolutely safeguarding the authority of the Party Central Committee and centralized and unified leadership is the core of upholding the party's leadership. At the beginning of the founding of the party, because there was no strong and powerful leadership core and no unity of the whole party, the cause of the party and the people suffered setbacks and even faced the danger of failure. The Zunyi Conference held in January 1935 established the leadership position of Comrade Mao Zedong in the Party Central Committee and the Red Army, and began to establish the leadership position of the correct Marxist line represented by Comrade Mao Zedong in the Party Central Committee, saving the party, the Red Army and the Chinese revolution at the most critical moment. Our Party United and led the Chinese people to defeat Japanese imperialism, overthrow the reactionary rule of the Kuomintang, complete the new democratic revolution, and establish the people's Republic of China. After reform and opening up, Comrade Deng Xiaoping stressed: "the Central Committee must have authority. To succeed in reform, we must have leadership and proceed in an orderly manner." The party's 100 year history has fully proved that it is precisely because of the authority and centralized and unified leadership of the Party Central Committee that China's revolution, construction and reform can continue to move from victory to victory, our party can always be strong and powerful, and our country can achieve long-term peace and stability.
