Chinese Discoveries Thru History

Amazing and eye opening list of discoveries made by folk in the realm of modern day China. I was clued on to this by my 6yo getting homework question about "how is he inspired by Li Shanlan". I had not heard of this person but diving into his history and finding about a 9 Arts of Mathematica written 2000 years ago and then happening on this list on Wikipedia. I am stunned.

Makes me wonder how many other amazing discoveries and thinking remains to be known globally and is just hidden due to culture, language, politics or repression. The libraries of Africa, scrolls of Tibet and Burma, and on and on.
