The work aims to deeply excavate and comb the local red context with the help of digital technology, design and construct a resource integration platform, so as to provide new ideas for protection and inheritance of red cultural resources in the information technology era and the post-epidemic era. With Chaozhou, an old revolutionary base, as an example, the spatial narrative theory was introduced to explore the information design method of the digital platform of red cultural resources. A regional red narrative framework composed of five elements of "Time-Event-Field-Person-Object" was proposed. With "information extraction-information processing-information presentation" as the steps, multiple digital technologies such as database, TGIS, hyperlink text and cloud platform were used comprehensively, and the three-in-one digital platform construction of "three-dimensional database & multimedia display & public communication" was put into practice. The introduction of spatial narrative theory is helpful to deeply explore the relationship among red cultural resources, sort out its spatial narrative elements, and establish a narrative structure model, so as to build a digital protection and dissemination information system for red cultural resources to provide the public with a digital environment for systematic and in-depth perception of red culture.
