In the important discourses on inheriting and promoting the great spirit of the Communist - Party of China, General Secretary Xi Jinping has put forward a series of original and landmark concepts. The "great founding spirit of the Communist Party of China" holds a very important position among them. In 2021, at the special historical node of the 100th anniversary of the founding of the Communist Party of China, General Secretary Xi Jinping officially proposed the great founding spirit of the Communist Party of China and summarized its profound connotations in the important "July 1st" speech. General Secretary Xi Jinping pointed out that "one hundred years ago, the forerunners of the Communist Party of China founded the Communist Party of China and formed the great founding spirit of adhering to truth, upholding ideals, fulfilling the original aspiration, shouldering the mission, fearing no sacrifice, fighting bravely, being loyal to the Party, and living up to the people. This is the source of the spirit of the Communist Party of China". He put forward the important requirement of "always inheriting and carrying forward the great founding spirit of the Communist Party of China". In November of the same year, the Sixth Plenary Session of the Nineteenth Central Committee of the Communist Party of China, in the form of a historical resolution of the Party, further discussed this important new - understanding of the Party, and established the source position of the great founding spirit of the Communist Party of China in the spiritual pedigree of the Chinese Communists. The source means the root, the beginning, and the cause. To deepen the understanding of the original and landmark concept of the "great founding spirit of the Communist Party of China", it is necessary to focus on the fundamental issue of the "source of the spirit". ### In - depth Understanding of the Party's Own Spiritual Essence The connotation of the great founding spirit of the Communist Party of China was formed in the process of the founding of the Communist Party of China more than 100 years ago, and has been continuously carried forward in the history of the Party's unremitting struggle in the past 100 - plus years. The process of the founding of the Communist Party of China was a process of the combination of Marxism - Leninism and the Chinese working - class movement, and also a process of the formation of the great founding spirit of the Communist Party of China. The lofty spiritual demeanor shown by the forerunners of the Communist Party of China in the process of Party - building and the long - term revolutionary struggle, such as Li Dazhao's "advancing bravely", "following with one's head cut off and blood shed", and "accomplishing with painstaking effort" for the belief in Marxism, Mao Zedong's far - sighted political vision, unwavering revolutionary belief, extraordinary courage to pioneer, perfect struggle art, outstanding leadership ability, sincere feelings for the people, magnanimous mind, and excellent style of hard work, Zhou Enlai's regarding himself as the "chief servant" of the people and his dedication until death, all gave birth to, formed, and vividly reflected the great founding spirit of the Communist Party of China. They are the personifications of the great founding spirit of the Communist Party of China. The formation of any scientific concept is closely related to historical practice and the revelation of the essence of things. The proposal of the great founding spirit of the Communist Party of China is an inevitable result of the Party's continuous deepening of its understanding of its own spirit on the basis of a century of historical accumulation. General Secretary Xi Jinping has made unique and outstanding contributions in this regard. The Communist Party of China has always cherished its precious spirit and defined its own spirit as "revolutionary spirit". During the New Democratic Revolution period, Mao Zedong pointed out that "this army has the spirit of pressing forward indomitably. It will overwhelm all enemies and will never be subdued by the enemies. No matter how difficult and hard the situation is, as long as there is still one person left, this person will continue to fight" and "make up one's mind, fear no sacrifice, surmount all difficulties, and strive for victory". These all reflect the fundamental requirements of this revolutionary spirit. After the founding of the People's Republic of China, in the face of the problem of the decline of revolutionary will of some Party members and cadres, Mao Zedong seriously demanded that "we should maintain the same drive, the same revolutionary enthusiasm, and the same fighting spirit as in the revolutionary war period, and carry out the revolutionary work to the end". During the new period of reform, opening up, and socialist modernization, Deng Xiaoping required all Party members to devote themselves to the great cause of reform and opening up with a firm revolutionary spirit and a high - spirited fighting will, just like in the revolutionary war period. He believed that "if a Communist Party member does not have these spirits, he can never be regarded as a qualified Communist Party member". Deng Xiaoping summarized the Party's revolutionary spirit as the "five revolutionary spirits" and pointed out that "in the long - term revolutionary war, under the guidance of the correct political direction, starting from the analysis of the actual situation, we carried forward the spirit of revolution and struggle, the spirit of strict discipline and self - sacrifice, the spirit of selflessness and putting others first, the spirit of overwhelming all enemies and difficulties, and the spirit of adhering to revolutionary optimism and surmounting all difficulties to strive for victory, and achieved great victories". General Secretary Xi Jinping is the main representative of the Communist Party of China in tracing the origin of its own spirit. As early as June 2005, in the important article "Carrying Forward the 'Red Boat Spirit' and Marching at the Forefront of the Times", Xi Jinping, then Secretary of the Zhejiang Provincial Party Committee, pointed out that "the 'Red Boat Spirit' is the source of the Chinese revolutionary spirit. The fine traditions and revolutionary spirits formed in the history of the Communist Party of China are all directly related to it", which is a preliminary exploration of the "source of the Party's spirit". In March 2007, Xi Jinping's first public appearance after taking office as Secretary of the Shanghai Municipal Party Committee was to lead the relevant leading - group members of Shanghai to pay homage to the sites of the First and Second National Congresses of the Communist Party of China, aiming to receive revolutionary traditional education, review the glorious course of the Party, cherish the great achievements of the Party, learn the lofty spirit of the revolutionary forerunners, further stimulate the enthusiasm and fighting will for the unremitting struggle for the cause of the Party and the people, and build Shanghai into a better place. On the occasion of the 95th anniversary of the founding of the Communist Party of China in 2016, General Secretary Xi Jinping further put forward the important requirements of "maintaining the fighting spirit of the Chinese Communists at the time of the founding of the Party" and "remaining true to the original aspiration". On the basis of in - depth thinking, in the important speech at the celebration of the 100th anniversary of the founding of the Communist Party of China in 2021, General Secretary Xi Jinping solemnly proposed the great founding spirit of the Communist Party of China and summarized its profound connotations, pointing out that "the great founding spirit of the Communist Party of China is the source of the spirit of the Communist Party of China". This important discourse, from the new historical height of the 100th anniversary of the founding of the Communist Party of China, deeply analyzes the "meta - problem" of the Party's great spirit, and deeply understands the original spirit of the Party from the whole process of the forerunners' founding of the Party, rather than from a specific time and space, which is highly general and has a historical depth. General Secretary Xi Jinping's definition of the connotation of the great founding spirit of the Communist Party of China is not only a profound revelation of the historical connotation of the fighting spirit at the time of the Party's founding, but also a profound revelation of the common essence of the great spirits cultivated and the spiritual wealth accumulated by the Party over the past 100 - plus years. It centrally reflects the Party's firm belief, fundamental purpose, and fine style, condenses the great qualities of the Chinese Communists, such as hard - work, sacrifice, dedication, and pioneering, and contains the profound truth of "why the Communist Party of China can" that has been tested by more than 100 years of historical practice. The "source of the Party's spirit" is the origin, source, and fountain of the generation and existence of the Party's great spirit and other spiritual wealth, and is the fundamental source that the Party's great spirit and other spiritual wealth run through and reflect. The proposal of the great founding spirit of the Communist Party of China and other related concepts is the fundamental symbol of the Party's reaching a new realm in understanding its own spirit, which enriches and develops the theoretical treasure - house of Marxist party - building, and opens up a new vision for understanding the history of the Communist Party of China. "Adhering to truth and upholding ideals" indicates the Communist Party of China's firm belief in Marxism and its firm belief in the grand ideal of communism since its birth. This is the political soul of the Chinese Communists and the spiritual pillar for the Chinese Communists to withstand various tests. "Fulfilling the original aspiration and shouldering the mission" indicates the Communist Party of China's firm spiritual pursuit of faithfully practicing the original aspiration of seeking happiness for the people and shouldering the historical mission of rejuvenating the nation since its birth. "Fearing no sacrifice and fighting bravely" indicates the powerful spiritual force of "daring to fight and daring to win" that the Communist Party of China has had since its birth, highlighting that the courage to fight is the innate political gene of the Communist Party of China and a distinct character tempered over more than 100 years. "Being loyal to the Party and living up to the people" indicates the noble spiritual quality that the members of the Communist Party of China have been unconditionally loyal to the Party's belief, the Party organization, and the Party's theories, lines, principles, and policies since the founding of the Communist Party of China, and have always adhered to the fundamental purpose of serving the people wholeheartedly. From the moment of its founding, such an advanced political party with a solid spiritual pillar, a strong spiritual pursuit, a powerful spiritual force, and noble spiritual qualities will inevitably radiate a strong historical initiative to transform the world, lead the people to strive unremittingly, move forward bravely, and continuously push the great cause of building a strong country and rejuvenating the nation to new heights. The Party's theory develops while adhering, and the Party's spirit is carried forward while adhering. Under different historical conditions, the great founding spirit of the Communist Party of China is given different connotations and requirements of the times. Facing the new situation and tasks in the new era and on the new journey, to carry forward the great founding spirit of the Communist Party of China, we must firmly establish confidence in Xi Jinping Thought on Socialism with Chinese Characteristics for a New Era, unremittingly use the latest achievements of the Party's innovative theory to gather the mind and strengthen the soul, and continuously consolidate the common ideological foundation for the unity and struggle of the whole Party and the people of all ethnic groups across the country. We must adhere to the people - centered development ideology, highlight the people - oriented nature of China's socialist modernization, and comprehensively promote the great cause of building a strong country and rejuvenating the nation with Chinese - style modernization. We must dare to fight and be good at fighting, and open up a new world for career development through tenacious struggle. We must adhere to the overall leadership of the Party, firmly safeguard the authority of the Central Committee of the Communist Party of China and its centralized, unified leadership, and be more conscious of maintaining a high degree of consistency with the Central Committee of the Communist Party of China with Comrade Xi Jinping as the core in ideology, politics, and action.
