By examining the dynamic patterns of online search trends related to the film, the study offers valuable insights for stakeholders in the film industry, the education sector, and related decision-making fields. Methods: Utilizing the Baidu Index—an open-access data analysis tool that leverages Baidu’s vast search engine data—this study used The Teacher’s Diary as the primary keyword. Search volume data were collected from March 20, 2014, to March 19, 2025, across China.
