Specific setting method:
1. First, click on the top right corner of the personal page.
2. After opening the list of Tik Tok settings, click the "Privacy Settings" option.
After opening it, we found that we were allowed to recommend it to our friends. If we don't want our friends in the address book to see it, click the lock button at the back, and it will turn gray after clicking. In this way, Tik Tok will no longer recommend you to friends according to the address book.
