Methods: A total of 443 junior high school students were surveyed by questionnaire survey and interview, and 9 of them were interviewed. Results: 39.73% of junior high school students chased stars, and junior high school students had more substantive appreciation for stars than superficial appreciation. Star-chasing has brought many positive effects to junior high school students, such as improving learning motivation and relieving stress. Based on the above survey results, suggestions are put forward for the guidance of junior high school students’ star chasing, such as positive guidance and setting boundaries.展开更多
