# 10

小的时候曾经赶过火车。不能直达，要在中间某站换乘。如果错过，就要去改签等待另外一次。有些错过可能没有这么幸运。错过了，就没有预期。早安，世界。早安，未来。早安，给不等待的你。

# 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/2017/11/10.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.
