Ethical review
Ethics approvals were obtained from two institutions: the Human Ethics Office at The University of Queensland in Australia (approval number: 2021/HE000791) and the Research Ethics Office at Tianjin Normal University in China (approval number: 2021041901). Informed written consent forms were obtained offline from both the participants and their guardians as most of the participants were under the age of 18 at the time of the trial. Participation was voluntary, and all students were informed that their answers would remain confidential. Only the first author had access to identifiable information during and after data collection. All participants were anonymized prior to data analysis.
