National unity is the lifeline of the people of all ethnic groups in China, and the sense of Chinese national community is the foundation of national unity. The Party unswervingly follows the correct path of solving ethnic problems with China characteristics, insists on building a strong sense of the Chinese nation community as the main line of the Party's ethnic work, and promotes the common unity, struggle and prosperity of all ethnic groups. The Party creatively combined Marxist ethnic theory with the specific reality of ethnic problems in China, and established ethnic theories and policies with ethnic equality, ethnic unity, regional ethnic autonomy and common prosperity and development of all ethnic groups as the main contents. All ethnic groups have achieved real equality, unity and progress under the socialist system. Building a strong sense of community of the Chinese nation is an inevitable requirement for safeguarding the fundamental interests of all ethnic groups. We should firmly grasp the main line of building the consciousness of the Chinese nation community, deepen the education of national unity and progress, guide the people of all ethnic groups to firmly establish the community concept of sharing weal and woe, sharing weal and woe and sharing destiny, gradually realize the all-round embedding of space, culture, economy, society and psychology, constantly consolidate the ideological foundation of the Chinese nation community, and promote all ethnic groups to hold together like pomegranate seeds in the big family of the Chinese nation. Cultural identity is the deepest identity.
