# 27

山或许远其实近\
城或许旧其实新\
人或许流传或许登临\
或许在山顶\
收获来自未来的信\
云一点一滴\
路过或者遥望\
这一群\
那一群

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://www.oulan.com/2025/04/27.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
