Yep lol, you will sometimes see a lot of neigong texts try and shoehorn modern scientific terms and concepts into it all.No offense, but I have never seen documentation for anyone knowing about genetics in ancient times, nor about the specifics of the immune system. People might have known some basics, like about how being exposed to small amounts of some things can make you resistant to them, but beyond that, they were pretty ignorant.
