Red culture embodies the epic narrative of the Chinese nation's journey from hardship to glory, carrying within it a profound sense of patriotic sentiment. It constitutes both a precious spiritual legacy of the Chinese people and an indispensable dimension of youth education in the new era. By virtue of its distinctive temporal scope and rich humanistic content, history as a discipline provides fertile ground for cultivating students' patriotism. The high school years represent a critical period in the formation of students' worldviews and value systems, and therefore a particularly important stage for patriotic sentiment education. In recent years, accelerating globalization and the expansion of the information environment have exposed adolescents to a multiplicity of cultural influences, contributing to blurred historical consciousness, a weakened sense of national identity, and a diminished sense of social responsibility among some young people. Against this backdrop the effective integration of red culture into high school history instruction has emerged as a pressing challenge for educators.
