If you want to add books to your Douyin video, before shooting the video, you can place the books that appear in the video in the shooting area in advance, and then shoot the video. When shooting, you need to pay attention to the placement and angle of the books to avoid affecting the video effect.

1. Open the Douyin application and select the video to be published.

2. In the video editing page, click the sticker button in the lower left corner, select "icon" or "emoji", and then enter "book" or search for relevant keywords.

3. Select the relevant sticker and drag it to the appropriate position, adjust the size and angle, and ensure that the book can be clearly seen.

4. If you want to add text content, select the "subtitle" function in the editing page, enter the relevant text, and you can also select parameters such as font and color to adjust.

5. After editing, you can preview and adjust the video, and then confirm the release.
