 ### 2. Daily Note Attribute Specifications
 
-When creating a diary in SiYuan, a custom-dailynote-yyyymmdd attribute will be automatically added to the document to distinguish it from regular documents.

 > For more details, please refer to [Github Issue #9807](https://github.com/siyuan-note/siyuan/issues/9807).
 
 Developers should pay attention to the following when developing the functionality to manually create Daily Notes:
 
-- If `/api/filetree/createDailyNote` is called to create a diary, the attribute will be automatically added to the document, and developers do not need to handle it separately.
-- If a document is created manually by developer's code (e.g., using the `createDocWithMd` API to create a diary), please manually add this attribute to the document.

 ### 2. Daily Note 属性规范
 
-思源在创建日记的时候会自动为文档添加 custom-dailynote-yyyymmdd 属性, 以方便将日记文档同普通文档区分。

 开发者在开发手动创建 Daily Note 的功能时请注意：
 
-- 如果调用了 `/api/filetree/createDailyNote` 创建日记，那么文档会自动添加这个属性，无需开发者特别处理。
-- 如果是开发者代码手动创建文档（例如使用 `createDocWithMd` API 创建日记），请手动为文档添加该属性。
