The Douyin details page can contain advertisements, but it is not necessarily pure advertisements. The Douyin details page is the page that users enter when they click on a video or actively search for it. It displays the creator information of the video, interactive content such as likes and comments, and related recommended videos. Although brand advertisements or commercial promotions may appear on the details page, it also provides users with an opportunity to gain in-depth understanding and interaction, allowing users to have a more comprehensive understanding of the content creators and share their own opinions and feelings. Therefore, the Douyin details page can be considered a platform for content display and promotion, which includes both advertisements and user-generated content.
