The theme names of the Double Eleven live broadcast can be named according to different goals and styles. One way is to take the promotion as the theme, such as shopping spree or quick purchase feast, and highlight the special price and limited time discount in the live broadcast. Another way is to take entertainment and interaction as the theme, such as a star party or a wonderful game show, and emphasize the star guests and interesting interactive links in the live broadcast. You can also combine brand features or product features, such as fashion show or new technology product launch conference, to highlight brand fashion or technological innovation. And you can also consider interacting with users and collecting their opinions and suggestions, such as collecting users' voices or naming them. I will broadcast them live to increase users' participation and interest in the activities. In short, the title of the topic should be attractive, unique and consistent with the content of the activity.
