"Intelligent Answer" function in Huawei Developer website
The original webpage is in Chinese, so better to use Chrome to open, https://developer.huawei.com/consumer/cn/doc/search , and "Translate to English", in the input field with black "search" button, try input "What is node in ArkUI? (in English)", and click "search", you will get reply in "Intelligent Answer" under it. If no full reply, like part of sentence was shown, just try once more.
If you try "What is node in ArkUI?" without "(in English)", it often replies in Chinese.
