 ### Precautions
+
 - Overall Requirements
     - The comment items required for a class or method are as follows: `Summary`, `Args`, `Returns`, and `Raises`. If a function does not contain related information (such as `Args`, `Returns`, and `Raises`), do not write None (for example, `Raises: None`), but directly omit the comment item.
     - When an API is generated by directory, the comments in the \_\_init\_\_ file header are displayed at the beginning of the web page. When an API is generated by file, the comments at the beginning of the file are displayed at the beginning of the web page. The comments must contain the overall description of the corresponding modules.
@@ -90,96 +94,113 @@ Outputs:
     - If the return value type or dimension changes, describe the relationship between the return value and the input.
     - If there are multiple return values, write them in different lines. The line difference is not displayed on the web page. The unordered list supports return values in different lines.
 - `Examples` Comment
-    - For the content in `Examples`, add ```>>> ``` at the beginning of each line of code (including empty lines). It should not be added to the output result.
+    - For the content in `Examples`, add ```>>>``` at the beginning of each line of code, and add ```...``` at the beginning of each line of multiple lines of code (including class or function definitions, artificial line breaks, etc.) or empty lines. No sign is required at the beginning of the output result line.
     - Actual code needs to be provided in `Examples`. If you need to refer to other Examples, use Note.
     - The comments of the ops operator are written in PyNative mode. If the operator can be executed, the execution result must be provided.
     - Import can be omitted in the case of industry consensus, such as np and nn.
     - If the import path is long or a user-defined alias is required, add `from xxx import xxx as something` or `import xxx`. If the import path is short, place it in the code.
 - `Inputs` and `Outputs` Comment
-    
+
     - If the data type is Tensor, describe the shape in the format of :math:`(N, C, X)`.
 - Formula
     - Line formula (in the middle of the singly occupied line)
-      ```
-      .. math::
 
-         formula
-      ```

-      ```
+
+        ```rst
+        xxx :math:`formula` xxx
+        ```
+
     - If the formula contains an underscored variable and the underscore is followed by multiple letters (for example, xxx_yyy) , select one of the following methods based on the site requirements:
         1. Multiple letters are enclosed in braces ({}), for example, xxx_{yyy}. The content following the underscore can be used as the subscript, which is displayed as $xxx_{yyy}$.
         2. If a backslash (\\) is added before an underscore (_), for example, xxx\\_yyy, the complete variable name is displayed as xxx_yyy.
 - Parent Class Method Display
-  - By default, the parent class method is not displayed.
-  - You can add `:inherited-members:` to the module of the RST file in the Sphinx project to specify the parent class method to be displayed. For details, see <https://www.sphinx-doc.org/en/master/usage/extensions/autodoc.html>.
