Tiktok is a visual and audio communication forum containing a variety of videos used by mostly millennial teenagers. How to use TikTok is similar to other social media: first create an account, then play by scrolling from the top to the bottom of the screen, and the current information will be displayed as a video. Tiktok has many fans, especially teenagers. The rise of this application may cause a change in the values of civility in social media.
