This is a randomized, parallel-group, two-arm study design registered with the Chinese Clinical Trial Registry. The study divides participants into an intervention group and a control group in the same ratio. The participants in the intervention group will receive a series of game-based activities and treatment. Firstly, we will distribute the recruitment advertisements for this intervention program in the school, including the project introduction, registration code, and contact details. Secondly, if students are interested in this project, they need to screen the code, and completely fill in personal information, and the screening questionnaire. Thirdly, students reaching the inclusion criteria and their parents will be invited to participate in a project briefing session and obtain their informed consent. Lastly, three times assessments in the whole process will be conducted, preintervention(T0), post-intervention(T1), and at a three-month(T3) follow-up. Importantly, participants can quit the project at any time during the whole process.
