Help Us

We need you

Kuaiyizhi has a lot of content: courses, experiments, interview questions, articles… We want all of it to be accurate, clear, and useful.

But the more content there is, the harder it is to make sure every part is perfect. We keep reviewing, checking, and revising, yet the site is genuinely large. Reviewing everything on our own takes a great deal of time and effort, and mistakes are still inevitable.

So we sincerely hope you can help us make it better.

How to help: find a problem, tell us

If you notice anything wrong while reading, you can tell us directly.

• On any page, scroll to the bottom and you will see a “Send feedback” button. Click it, describe the issue, and submit.
• You can also submit feedback through the “Feedback” link in the footer, which takes you to the feedback page.
• If you prefer GitHub, you can file an issue at CofficLab/FeedbackHub.

What kind of feedback is helpful

Anything that makes you think “this doesn’t look right” is worth telling us, for example:

• Content errors: typos, incorrect formulas or code, inaccurate explanations;
• Unclear explanations: something is hard to follow, key steps are missing, examples are not enough;
• Broken links: links on the page do not work or point to the wrong place;
• Display issues: broken layout, missing images, problems on mobile.

Feedback does not need to be formal. A sentence or two is fine. Point out where the problem is and briefly describe what you encountered—that already helps us a lot.

What happens after you submit

We see every piece of feedback, note it down, and do our best to address it.

However, we are a small team and much of this work is done in our spare time, so fixes may take a while. If your feedback is not handled immediately, please be patient—we have seen it and written it down. The pace may just not be as fast as a mature commercial product.

Slow work produces fine work. We want every fix to be careful, not hasty.

Thank you

The few minutes you spend writing a piece of feedback may save countless future readers from the same confusion. Making knowledge more accurate and clearer is something we do together.

Thank you for your help.
