Was there a modification to the tutorial? Could you clarify this part

Hey @RUNQILIU-123 and Suylang, great review of the existing tutorial. I've reviewed all the screenshots and they seem good.

I had a quick questions because the review had a line saying there was a text description that was modified, could you clarify if this is the description of the tutorial itself? And if so could you include the change in this PR?

I approve this PR

The greatest advantage of this node is that the tutorial structure is clear, covering multiple language implementations and being runnable. It is recommended to supplement error handling and automated verification (CI badge and log screenshots), cross-platform operation guidelines, as well as PR links and version lock information. This can significantly enhance reproducibility and engineering credibility, and is also more in line with the standards of "high quality and maintainability". I think this pr is very good!

It is recommended to supplement error handling examples for non-200 response and timeout scenarios, and attach running screenshots to enhance reproducibility.
