Parent-child relationship issues of middle school students are important issues that affect their individual physical and mental development. As a result of the COVID‐19, large‐scale online education is taking place across the country. To understand the parent‐child relationship status of junior high school students in the home online education environment, this study conducted an empirical investigation on junior high school students and their parents. The results of the study showed that the parent‐child relationship of middle school students in the home online education environment changed significantly under the influence of various factors, including parent‐child time, parent‐child communication and interaction, parents' tendency to care, parents' guidance and assistance to their children, and children's learning status. It is expected that the research study will propose empirical‐based countermeasures for educational administrators, teachers, parents, students, and other practice subjects, to promote a healthier and more harmonious development of parent‐child relationships among junior high school students.
