Improve the media literacy of teenagers, guide them to use the internet reasonably, and actively discover beauty while refusing to indulge in the internet when facing short videos. Currently, the impact of short videos on teenagers is gradually deepening. Through short videos, some students follow experts, scholars, and science bloggers to discover the "sea of stars" of their interests and hobbies; Some students are attracted by funny videos and popular jokes, and their phones are gradually becoming more affordable and difficult to put down. What distance and relationship should teenagers maintain with short videos? This has become a problem that many teachers and parents have to face. According to the 2021 National Research Report on Internet Usage among Minors, over 60% of underage netizens often watch short videos among students in middle school, high school, and secondary vocational education; The most commonly watched short video content among underage netizens is humorous content, accounting for 66.4%, followed by leisure content. A sampling survey shows that 33.4% of teenagers agree to varying degrees with 'I can't tolerate not having a phone', and more than one-third of teenagers may have an impact on their learning and life due to using a phone. Why do short videos make some teenagers "addicted"? On the one hand, the magnified visuals, exaggerated soundtracks, and dramatic editing of short videos create an immersive viewing experience for users. Algorithm recommendation functions such as "Guess You Like" have formed a push cycle where the longer the usage time, the more accurate the user information, and the more similar content. On the other hand, teenagers have a strong curiosity and exploration desire, and a large number of novel and interesting short videos meet their psychological needs. Watching short videos at close range for long periods of time not only damages vision and affects physical health, but may also lead to distraction and make it easier for minors to become accustomed to instant gratification while neglecting learning, exercise, etc. This is worth our vigilance. In recent years, short video applications have launched "youth mode" one after another. However, the survey found that the utilization rate and satisfaction of this model need to be improved. The reason is that some "Teenager Mode" passwords have too few digits and do not need face recognition. It is not difficult for teenagers who are familiar with their parents' ID number numbers and setting habits to crack them. More importantly, some "youth mode" content pools are relatively single, unable to meet the viewing needs of adolescents of different age groups. Preventing teenagers from becoming addicted to short videos requires joint efforts from all parties. While upgrading the 'youth model', it is also necessary to strengthen 'youth care'. From the perspective of family education, parents should lead by example, put down their phones first, strengthen parent-child communication, and create a loving and interesting family atmosphere through high-quality ways of getting along, such as exercising and reading together. From the perspective of campus education, schools should vigorously recommend extracurricular reading materials and video materials suitable for teenagers, and guide students to actively lead a spiritual and cultural life. From the perspective of platform responsibility, the truly useful "youth mode" is not the "simplified version" of ordinary browsing mode. Short video applications should actively add and produce and recommend more high-quality puzzle content according to the diverse interests and hobbies of young people, fully meeting their viewing needs. Today's teenagers are indigenous people in the internet age, and their learning and life are inseparable from the internet. The lively knowledge Q&A in the short video, compared to
