Abstract: During the Long March of the Red Army in Sichuan, the Communist Party of China, in order to realize the strategic transfer of the Red Army, centered on the primary task of the Long March, constantly updated and enriched the ideological and political education work with unity as the main content, and played a powerful function of the lifeline of ideological and political work. The Communist Party of China (CPC) has adopted flexible educational methods, carried out targeted education work for different classes, and strengthened the thoroughness and effectiveness of the struggle against the enemy with unity education as the starting point. With the goal of unified struggle against the enemy, we unite and educate not only ethnic and religious leaders but also the masses of ethnic minorities, which not only strengthens revolutionary forces but also gathers revolutionary consensus. The practice of unity education in Sichuan ethnic areas during the Long March period provided valuable experience for the Communist Party of China in the new era to strengthen the consciousness of the Chinese nation community.
