You have significant advances in math, science, and technology. This is an image of the nine chapters on the mathematical art, where ideas like Gaussian elimination and Cramer's rule, things that wouldn't be explored in Europe for over a thousand years, are documented during Han China. You have the famous paper-making emerge during Han China, and as you can see, it lasts for over 400 years. There's a brief period right over here where you have the Qin Dynasty gets established, and that separates the Western Han from the Eastern Han, but this is a significant period of development of Chinese philosophy, Chinese writing, Chinese technology that lasts even until today. And to get an appreciation of the Confucian philosophy, remember, Confucian lived over several hundred years before the Han Dynasty, but this is when it really becomes the philosophy, or even you could think of the religion of China. I'll leave you with a few quotes from Confucius, and I'll do a whole video on him later on, but these are some of my favorite. Real knowledge is to know the extent of one's ignorance, and this is a version of the Golden Rule.
