Today, we will hold the 9th collective learning session of the 20th Central Political Bureau, which aims to strengthen the awareness of the Chinese nation as a community. The purpose of arranging this collective learning is to summarize the significant achievements in ethnic work since the establishment of the People's Republic of China, especially in the new era, analyze the new situation and challenges faced by ethnic work, and study the issue of further strengthening the awareness of the Chinese national community and promoting the high-quality development of the Party's ethnic work in the new era. Since ancient times, the people of all ethnic groups in China have jointly created a brilliant and dazzling Chinese civilization, and forged the great Chinese nation. Since its establishment, our party has attached great importance to ethnic issues and ethnic work, and correctly handled ethnic relations. After the establishment of the People's Republic of China, the Party established ethnic theories and policies with ethnic equality, ethnic unity, regional ethnic autonomy, and common prosperity of all ethnic groups as the main content. All ethnic groups achieved true equality, unity, and progress under the socialist system. In the new era of reform and opening up, our party adheres to the common unity, struggle, and prosperity of all ethnic groups, adopts a series of major measures to support the economic and social development of ethnic regions, and has achieved significant achievements. Since the 18th National Congress of the Communist Party of China, our party has emphasized the concepts of the Chinese nation as a big family, the Chinese nation as a community, strengthening the awareness of the Chinese nation as a community, and promoting the construction of the Chinese nation as a community. We have clearly proposed that strengthening the awareness of the Chinese nation as a community should be the main line of the party's ethnic work in the new era, as well as the main line of work in ethnic areas, to further expand the correct path of solving ethnic problems with Chinese characteristics, The important ideology of the Party on strengthening and improving ethnic work has been formed, and a new realm of sinicization and modernization of Marxist ethnic theory has been opened up. The Party's ethnic work has achieved new historic achievements. To strengthen the sense of community among the Chinese nation is to guide people of all ethnic groups to firmly establish the concept of a community that shares weal and woe, honor and disgrace, life and death, and destiny. Taking the strengthening of the sense of community among the Chinese nation as the main line of the Party's ethnic work and various work in ethnic areas in the new era is a significant theoretical and practical achievement that our Party adheres to the "two combinations" and focuses on the "two overall situations", deeply summarizes the experience and lessons of ethnic work at home and abroad, and deeply understands the development trend of the Chinese nation community. This major concept enriches and develops Marxist ethnic theory, consolidates and expands the correct path of solving ethnic problems with Chinese characteristics, and points out the direction of the Party's ethnic work. After the 20th National Congress of the Communist Party of China, the people of all ethnic groups across the country embarked on a new journey to comprehensively promote the construction of a strong country and the great cause of national rejuvenation with Chinese path to modernization. The Party's national work is facing new situations and tasks. To comprehensively build a socialist modernized strong country, no nation can be left behind. We must vigorously promote the common unity and struggle of all ethnic groups, and gather tremendous strength for the construction of a strong country and the rejuvenation of the nation; To comprehensively achieve the common prosperity and development of all ethnic groups, and to enable people of all ethnic groups to share the great glory of building a strong country and national rejuvenation. We must fully implement the deployment of the 20th National Congress of the Communist Party of China, accurately grasp the new stage characteristics of the Party's ethnic work, consolidate a good situation, solve the contradictions and problems in actual work, continuously strengthen and improve the Party's ethnic work, and solidly promote the cause of ethnic unity and progress. Firstly, based on the long history of the Chinese nation, strengthen the theory of a Chinese national community
