I'm learning Chinese, and in particular I'm interested in studying university-level mathematics in Chinese. I study Chinese while making YouTube videos; the existence of a (largely imaginary) audience has two language-learning benefits: (a) I tend to pay more attention, thinking that someone is watching, and (b) I tend to recap for the audience what has been said, and give my own thoughts.
I found this Chinese linear algebra course from MIT. This is exactly what I'm after, but there's only 6 videos. I'm hoping there's more videos like this, and ideally with a license like the MIT videos where it's unproblematic for me to make YouTube videos without copyright concerns.
Question: Where can I find recorded mathematics lectures in Chinese?
Searching the MIT website like this didn't give me anything in Chinese.
