Although young, the problem is not small. "Just uninstalled the software, the child secretly installed it again! What should I do?" Wang Lihua, a resident of a parent group in a community in Xiamen, Fujian Province, sent a message for help. These days, the first thing children do when they come home from school is to play short videos, which not only delays sleep but also leads to a sharp drop in academic performance. What makes Wang Lihua even more headache is that the short videos pushed by the platform are not suitable for elementary school students to watch. After confiscating the phone, the child cried incessantly and had no intention of studying. She began to worry about her child falling into "short video addiction". Such children are not uncommon. The National Mental Health Assessment and Development Center of the Institute of Psychology of the Chinese Academy of Sciences conducted a survey of primary and secondary school students across the country, which showed that 33.4% of teenagers agreed with "I can't stand not having mobile phones". Addiction to the internet not only affects learning. It may seem like "brushing" during leisure time, occasionally "taking a look", and casually "taking a photo", which may contain multiple risks - in order to make huge profits, some applications spread superstitious violence, pornography, and vulgar information to minors through short videos, game equipment, emoticons, etc. Recently, Beijing resident Wang Peng discovered that his son, who was studying in high school, was browsing an online forum with several links on the screen. He needed to register and pay to log in. Out of concern, he paid a "membership fee" of 60 yuan and found that all of them were vulgar videos. These negative information not only affect the physical and mental health of minors, but also induce them to go astray: 10 year old elementary school students reward online anchors, spending 170000 yuan on their mother; 15-year-old boy addicted to online gambling, stealing 27000 yuan from his parents; A 14-year-old boy who jumped out of a building after being scolded for playing games, resulting in lifelong disability and still struggling to quit internet addiction... These shocking cases have frequently sparked social discussion. Xian Jie, Director of the Ninth Procuratorate of the Supreme People's Procuratorate, provided a set of data: from January 2020 to September this year, procuratorial organs prosecuted 11600 adults suspected of using telecommunications networks to commit crimes against minors. There are still loopholes in "anti addiction". In recent years, with the strong promotion of relevant national departments, various short video and game platforms have launched "youth mode" or "anti addiction system". The reporter opened a certain short video platform and found that in the "Settings" menu, "Youth Mode" can be activated, with a maximum usage time of 40 minutes per day, and operations such as rewards, recharging, and withdrawals cannot be performed. Users need to enter a password to activate or deactivate youth mode. Many parents have expressed that the anti addiction system has a certain effect, and children's online time has indeed decreased. But for some unruly 'bear kids', they are still defenseless. It's difficult to completely eliminate children's dependence on the internet with just one system setting, "said Liu Yang, a resident of Haidian District, Beijing, At present, some large network platforms have established active triggering mechanisms for anti addiction systems - which can screen and screen underage users through technical means such as geographical location determination and user behavior analysis, and then self
