The specific method is as follows: 1. Open the "Props Popular" interface in Tik Tok, then click "Mirror Props", and then click the blank area of the screen to close the list of props.

2. Open the recording interface of Tik Tok, and then click the "Record" button directly. Because when you let your face appear in the mirror, you will become ugly and trigger the demon mirror.

3. After the special effects video starts recording, the mobile phone makes your face appear in the mirror, and then you become ugly. Then open your mouth, the mirror becomes a big mirror, and you become beautiful.

4. Open the video release interface after recording the mirror video, and the topic "# monster will appear soon" will be automatically added to the edit box. Do not delete, continue to edit the text, and then click "Publish".
