The editor of the WeChat public platform dialog box cannot be set. You can use third-party online editors such as 135 editor, big e-commerce editor and new media typesetting. These editors provide many styles for direct selection. Taking new media typesetting as an example,

1. Baidu searches for new media typesetting and enters the editor interface.

2. Click on the classification format on the left, and various pre-stored formats will be listed for selection.

3. After clicking a style, it will be automatically inserted into the editor on the right. After the overall editing is completed, copy and paste it directly into the editor of WeChat official account.

4. Other styles can be edited in the same way. You can also copy and paste the entire graphic message content into the editor of WeChat official account once after editing, save it and send it to the group.
