Emphasizing the importance of constructing an autonomous knowledge system for foreign language education in the context of globalization and intensifying international competition, for the high-quality development of China's education, enhancing its international influence, and strengthening cultural soft power. It points out the long-standing issue of "prioritizing introduction over originality" in China's foreign language education, which has resulted in a lack of autonomy and uniqueness in the knowledge system. Localization is proposed as the key to constructing this system, including the localization of value stances and theoretical core, emphasizing that it is not about exclusion but about integrating Chinese educational traditions with international experience. Five key pathways for achieving localization are proposed: integrating ideological and political education into the curriculum, localizing teaching content, adapting teaching methods, emphasizing practice-oriented approaches, and engaging in international dialogue, all aimed at cultivating talents with cross-cultural communication skills and cultural confidence.
