Under the background of deep integration of culture and tourism and the upgrading of study tourism, micro-performance becomes an important path for activating traditional culture and iterating study tourism products. From the perspective of the dramaturgical theory of tourism, this study takes the Hongdong Big Locust Tree Scenic Area as a case to build a four-dimensional analysis framework of “script, stage, performance, and front and back stage.” This study analyzes the application mechanism of micro-performance in root-ancestor culture research, points out the existing problems in its narrative, performance, technology, and management, and put forward optimization strategies such as cultural narrative innovation, double qualification system construction, digital technology integration, effect evaluation system construction, etc. It provides reference ideas for the development of similar cultural heritage research tourism.
