Ask HN: Is there a whole universe of Chinese software that we don't see?

China is obviously a major world player, but we rarely see articles/repos/posts/etc., that seem to originate from there, translated or not, or simply referred to. Are we missing out on lots of cool advancements from China? Or do Chinese engineers generally publish in English? Is there some massive Chinese GitHub with cool stuff we don't know about? Science is science and I can't shake the feeling that we're missing out on stuff, but I really have no idea. Would love to hear people's thoughts.
