大爱最近在用的这把公道杯。它有漏斗，不会使茶汤四溅，还可以过滤掉茶渣，又容量巨大，杯口合适，易于分享。我们学习知识也是这样。早安，世界。早安，未来。早安，学习中的你。

# 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/2017/07/04.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.
