I'm trying out LanguageCrush which tracks your vocabulary while reading and watching videos (kind of like LingQ, but I'm able to use the free version). The feature I like is how it keeps track of how much I've read. However, there's not much Chinese content on LanguageCrush. I can upload plaintext content, but I shouldn't violate copyright (NB. I don't have a deep understanding of international copyright laws).
So...
Question: Where can I get Chinese reading materials to copy/paste into LanguageCrush?
I've thought to copy/past Chinese Wikipedia pages, but I'm not sure how useful the content is (and I hear a lot of it is "translatese" anyway). Another option would be to get e.g. ChatGPT to generate content.
Ideally the content would be useful for someone studying for the HSK6, so using a semi-formal style, and including uncontroversial topics such as pop science, Chinese ancient history, architecture, geography, or those kind of "chicken soup for the soul" style stories.
