Summary
WeChat public-account articles are the entry that matters — that content is effectively invisible to a general web search.
A great deal of Chinese technical and industry writing lives inside WeChat's walled garden, where crawlers do not reach and search engines index poorly. Same for Xiaohongshu. If your questions touch the Chinese market, that coverage is the difference between an answer and a shrug — and it is not something you can substitute with a better prompt. YouTube subtitles are the other quietly useful one: the transcript without watching.
