[Question] Who are the worthwhile non-European pre-Industrial thinkers?

At some point I became decently widely read in “Western philosophy”, of the tradition that goes from Athens through Italy and Germany and Britain to the U.S. [ forking off into Philosophy and Science only after the Industrial Revolution ]. But somehow, I never acquired any operational sense of any of the corresponding “shadow” networks of writings that were only discovered by ‘Western’ philosophers to be published in Greek, German, Latin, or English after industrialization. Centrally, I’m thinking of East Asian, Indian, and Islamic authors, although there could be more philosophically productive pre-industrial cultures of which I’m ignorant.

I know there are compendia out there, but starting as I am from a position of almost total helpless ignorance on the object level, I trust random sources almost not at all to be discriminating on the actual value of people’s ideas.

My anemic existing context: I wouldn’t be a LessWronger if I hadn’t read Musashi, but as far as I know he just didn’t write much and wasn’t very much in dialog with the rest of “his” culture [like a Socrates who was never succeeded]. Years ago I tried to read Confucius and bounced, due to disagreeing with all of his opinions. I also tried Sun Tzu, but only bounced off him because I found tactics boring at the time, and might try him again. I’ve heard that both pre-Industrial India and 11C-13C Islam were expert at medicine and [more in Islam’s case] calculation, but I haven’t retained any specific names [other than al-Khwarizmi, who didn’t sound any more interestingly-idealist to read than, say, Blaise Pascal, though I could have misapprehended].

I’ve asked around and so far been recommended Mozi, who looks promising, and Xunzi. If you care to humor a cultural [& linguistic] monoglot’s embarrassingly Knightian uncertainties: wrt wherever your locality of expertise is, where should I start? What should I know first?
