"On the new way to catch up with the examination, whether we can continue to hand over excellent answers depends on whether we have firm historical self-confidence." *** It also stressed that "let the official history become the consensus of the whole Party and society, and educate the majority of Party members, cadres and all the people, especially the majority of young people, to strengthen their historical self-confidence, build a solid historical memory and move forward with confidence". "I am confident that if I live for 200 years, I will hit 3000 miles." Historical self-confidence is a deep and lasting force of a nation and a political party. Over the past 100 years, our party has been committed to working for the happiness of the Chinese people, the rejuvenation of the Chinese nation, the progress of mankind, the unity of the world, the public and the right path in the world. This is the greatest strength of our party's historical self-confidence, the historical self-confidence of our party's governance and long-term governance in China, and the historical self-confidence of our party in uniting and leading the people to move forward. History eloquently shows that without the Communist Party of China, there would be no new China, no happy life for the Chinese people, and no great rejuvenation of the Chinese nation. History and the people have chosen the Communist Party of China, and the Communist Party of China has lived up to the choice of history and the people. *** "Its beginning is also simple, and its completion will be huge." At the beginning of the birth of our party, few people expected to achieve such a great historical cause as today. The Centennial struggle of the party and the people has written the most magnificent epic in the history of the Chinese nation for thousands of years. The Sixth Plenary Session of the 19th CPC Central Committee comprehensively summarized the major achievements and historical experience of the party's hundred years of struggle. This impressive hundred year report card is written by generations of Chinese Communists with ideals and beliefs, forged with blood and life, and won with struggle and dedication. Every Chinese Communist has reason to be proud. The historical confidence of the Communist Party of China is not only the confidence in the achievements of struggle, but also the confidence in the spirit of struggle. "It seems to be the most unusual, but it is as easy as it is difficult." The reason why our party has experienced vicissitudes and is in its prime and full of hardships and vitality depends on the firm pursuit of ideals and beliefs and the persistent adherence to the original mission of the majority of Communists. The officers and men of the whole army should draw on the wisdom of the party's historical experience, deeply understand why the Communist Party of China can, why Marxism works, and why socialism with Chinese characteristics is good, constantly strengthen the "four self-confidence" and summon up their energy to march towards a new journey and forge ahead into a new era. At the same time, we should inherit the red gene from the glorious military history, understand the way to win the war, and better gather the willpower of military training and preparation. Historical cognition is an important basis of historical self-confidence. We should establish a correct view of history, adhere to using historical materialism to understand and record history, and deeply understand the great process of the development and growth of our party, country and army from official history. We should take a clear-cut stand against historical nihilism and any wrong tendency to distort and vilify the party's history, better straighten out the source, consolidate the foundation and cultivate the yuan, and win greater victory and glory in the new era and new journey with firm historical self-confidence.
