As of 2022, over 97% of minors in China use the internet. Major platforms have launched dedicated features to prevent urgent issues such as internet addiction among minors. To bridge the "last mile" of these features, enabling young people, families, and schools to use them correctly and consciously, the China Internet Network Information Center has organized systematic research to understand young internet users, aiming for positive social attention, policy improvement, and platform optimization. This study is based on annual surveys since 2018 of over 100,000 primary and secondary school students nationwide, their parents, and hundreds of teachers. The project helps society understand the situation and challenges of online protection for minors, promotes improvement of protective measures, and helps youth, families, and schools build confidence in using ICT. Through surveys, the project received effective feedback. Policy-wise, it provided useful assistance in revising the "Regulations on the Protection of Minors Online" regarding cyberbullying, privacy protection, and internet addiction, sparking social discussions. Commercially, it guided platforms like Tencent to introduce features addressing gaming, live streaming, and short video addiction in youth, along with privacy protection and mechanisms to prevent excessive online spending. Socially, the proportion of surveyed students free from any cybersecurity incidents in the past year rose from 66.0% in 2019 to 72.4% in 2022; the proportion of students aware of online rights protection and reporting increased from 69.1% in 2018 to 78.9% in 2022. This is a Lightning Talk without online sector, not a hybrid meeting.
