From the perspective of cultural and tourism integration, thispaper investigates and evaluates the red cultural resources in Yimeng old revolutionary base area, analyzescombined with the development status of red tourism, and puts forward targeted suggestions on thedevelopment of Yimeng red cultural resources through the investigation and analysis of tourists’ feelingsabout red tourism in Yimeng region.展开更多
