The nickname of Tik Tok guest account usually requires real-name authentication, so it may not be changed directly. If your nickname needs to be changed, you may need to unbind the guest first, and then change the nickname in Tik Tok. When editing nicknames, it is suggested that the names should be as simple as possible, and 3-8 words are appropriate. At the same time, we should consider whether it can reflect personal settings and positioning.
