1. First, open the Tik Tok application and create a birthday greeting video: use Tik Tok's shooting function to record a video specially made for birthday greetings. You can choose to express your blessings in the video, sing a song and do some interesting or creative actions.

2. Secondly, add birthday-related labels and music: Before the video is released, add birthday-related labels to the video, such as "Happy Birthday" and "Birthday Blessing", to make the video easier to find. You can also choose a music suitable for the birthday atmosphere as the background music.

3. Then edit and release the video: use the editing function provided by Tik Tok to edit the video simply, such as editing and adding filters. After editing, choose a suitable time to release the birthday greeting video.

4. Finally, share and tag: When posting videos, you can choose to share them with designated friends or post them to your personal Tik Tok account. You can mark the Tik Tok account of the birthday person in the video description to ensure that you can receive the blessing.
