If I keep chatting, does Tik Tok know if I will change my name?

Yes When chatting with other users on Tik Tok, the chat record will be saved in Tik Tok's server and associated with personal data, including user name or nickname, avatar, personalized signature and other information. When the user name or nickname changes, the personal data will also be updated, including the name displayed in the chat history. During the chat, a new user name or nickname will be used, and the other party will be able to see this new name.
