Through a distinctive dual-perspective narrative, this book places Chinese civilization and the contemporary Western world within the same historical frame. Following the intertwined fates of a hundred pairs of ordinary people, it portrays not only the spread of technology, the evolution of ideas, and the rise and fall of institutions, but also reveals how Eastern and Western civilizations made different choices when facing similar challenges, and the lasting echoes created by their collisions. This is an epic about how humanity shaped empires, faith, and the modern world.
