Industrial location factors constitute the fundamental basis for industrial development and spatial distribution. Regionally distinctive industries, grounded in unique local resource endowments and cultural heritage, possess signifi cant market competitiveness and development potential. Using the "Sour Soup" (Suantang) industry in Danzhai County, Guizhou Province, as a local pedagogical context, this study integrates the industry's history with its comparative advantages to construct a learning progression for regional geographic reasoning. By vertically articulating core curriculum concepts across middle and high school levels, the instructional design guides students to examine the integration of primary, secondary, and tertiary sectors through real-world inquiry. Ultimately, this approach aims to deepen students' understanding of industrial upgrading, foster higher-order thinking skills, and eff ectively cultivate geographic key competencies.
