A strong spirit is the source of strength for a Marxist party. Only a party with a great spirit can lead the people to win a great struggle and create a great cause. In the course of a hundred years of struggle, our Party has formed a great spirit of building the Party that adheres to truth, adheres to ideals, practices its original aspiration, undertakes its mission, is not afraid of sacrifice, fights bravely, and is loyal to the Party and lives up to the people. Over the past hundred years, generations of Communists have carried forward the great spirit of party building, demonstrated the great historical initiative, tempered distinctive political character, and formed a spiritual pedigree with the great spirit of party building as its source. Looking back on history, our Party's original aspiration is rock solid and its mission remains unchanged. The people of the CPC have written their glorious dreams on their own flags, demonstrating the unswerving faith and responsibility of a century old party. In the new era and new journey, building a modern socialist country in an all-round way and promoting the great rejuvenation of the Chinese nation in an all-round way are bound to face all kinds of major challenges, risks, obstacles and contradictions. We must always adhere to the original mission, continue the red gene, keep the original mission in mind, forge ahead, blaze new trails, and work hard and earnestly. Constantly strengthen the will and ability to carry out great struggle, maintain the heroic spirit of moving forward with difficulty, always maintain the political nature of the CPC, and strive to take a new road to the second centennial goal. In today's world, the CPC, the People's Republic of China, and the Chinese nation have the most reason to be confident if any political party, country, or nation can be confident. For a hundred years, the CPC has been committed to the happiness of the Chinese people, the rejuvenation of the Chinese nation, the progress of mankind, the common destiny of the world, and the justice of the world. This is the greatest confidence of our party in history. Possess Marxist scientific theory
