Will Tik Tok display the previous phone number?

Tik Tok will display the previous phone number. Not all the friends in Tik Tok's address book are very talented. As long as the other party's phone number exists in the mobile phone, it will appear in Tik Tok's address book list, but only if the other party is allowed to recommend me to friends in the privacy settings, and the previous phone number will be displayed in Tik Tok.
