One thing that happens as we get into the late Tang Dynasty is that there's pushback against Buddhism that we talk about in other videos, and you see Neo-Confucianism begin to take hold, and it really takes hold under the Song Dynasty that we talk about in other videos. Now the Song Dynasty is also known as a time of really putting a lot of energy into the civil service and the bureaucracy, and it really being very meritocratic, based on some of these Neo-Confucian ideals. It's also a time of significant technological innovation. The compass, which has use as early as the Han Dynasty, but it really gets into its fairly evolved or modern form, especially for maritime use during the Song Dynasty. The notion of a Chinese junk boat also gets into its evolved form during the Song Dynasty. Now some of the really far-reaching innovations from this dynasty include building on the Tang use of block printing, but thinking about movable type, which makes printing far more practical. And maybe the biggest single innovation that changed the world, for better or worse, was the use of gunpowder, which there's some use in the late Tang, but it really starts to get perfected during the Song Dynasty.
