Social media today exerts a substantial impact on how people view various social issues, especially among secondary students, the heaviest users of social media. This paper, based on empirical studies on the time and frequency of teenagers’ social media use, as well as the way they use social media to "follow" certain topics, attempts to address how social media influences the levels of empathy in secondary students. First-hand data of questionnaires and interviews are collected among secondary students in Foshan, Guangdong, China. The data is used to analyze the extent to which using different media platforms or following different content can result in different empathy levels.
