What lies at the heart of Chinese culture? How have the Chinese people and their government changed over time? The "Understanding China through comics" series answers these questions and more. "Division to unification in imperial China" explores the Age of Division, a period of civil wars and foreign invasions, through to the Golden Age of the Tang dynasty, at the time the most powerful empire in the world, and its ultimate collapse. This same era saw the spread of new ideas and religions, like the profound learning movement, Buddhism, and Taoism.
