To get a sense of that, here is China during the Three Kingdoms period in the third century, shortly after the fall of the Han Dynasty. You see the Jin Dynasty depicted here in the fourth century, still part of what's often known as this Six Dynasties period, this roughly 360 years of a fragmented China. And then you see this North and South Dynasty period here in the sixth century, and eventually China is reunified, and that happens under the Sui. It is unified under Emperor Wen of Sui, for whom the dynasty is known, and similar to the Qin, what the Sui are most known for as taking this chaotic period and finally unifying China. And the Sui are ethnically Han, and they lay the foundation for another Golden Age of China under the Tang and the Song Dynasties. The Tang Dynasty depicted here, it rivals the Han as a Golden Age of China. It's a time where the arts, the sciences, really come about.
