China was hardly feudal since the Zhou dynasty. Even if so, it's definitely not grug ooga booga tier; also, of course China and Japan weren't &quot;equal&quot; for most of their history, are you retarded? China has some periods of technological advancement like Song and Tang, Ming to some extent. Japan meanwhile was always a stagnant feudal shithole (a civilized, literate shithole) that copied everything from its neighbor uncle until sometime into sakoku and then Meiji. <|endoftext|> There was barely any substantial difference between who was more advanced during medieval times. They were both equally living out the grug ooga booga-tier feudal system, until the 1800s arrived, and then we see the introduction of modern science. I'm not saying this because I'm ignorant of the subject either; There's basically no scientific innovation during the Heian to Meiji period at all. In the Ancient world, I assume that China was more &quot;advanced&quot; (organized) hence their cultural spread, but everything afterwards is stagnation and very minor in terms of difference. <|endoftext|>
